Thanks and I agree, but how can you be sure I am not a zombie? (really, have you seen the state I am in?) Not all zombies are bad. (some are preserved well).
a word of thanks to you. never sell yourself short. as many of us here watched your presentation it was well understood, not boring at all. you may not believe it your system works as well as any other devices out there. keep sharing your knowledge with the world, we are listening. there will always be room for improvement in anything man does. do not stop,
Hello Giesbert Nijhuis: I've been an electrical engineer for 20 years, And I have some advise for improving the function and efficiency of your ceiling fan turned wind turbine. 1st: I like to say you have a firm foundation for creating your own free energy device. I believe that you're on the right track with this project. 2nd: I think that You needed to Keep those inner coils so that you could use them as a magnetic governor, to prevent over speeding the turbine, and thus keeping the raw input voltage from getting too high. "A simple 10 Mega-ohm power resistor" across the inner coils, would provide a semi-regulated load. and thus cause enough rotational resistance, to prevent an over speed event. A wire wound Variable resistor, or a rheostat used, instead of a straight resistor, would allow you to adjust the governor strength by adjusting the the inductive current flow caused by your magnets acting on the inner coils. Changing the resistance will in turn change the inductive load. allowing the turbine to spin faster or slower, depending on the load resistance on the inner coils. This is how to keep this wind turbine from frying your step down circuit(s) which will fail before anything connected to it will. Your power regulator, and DC converter are the weak links here. But if you can regulate the raw input voltage from your coils before it even gets to your power circuits, that weakness will be a non-issue. 3rd and finally: I would suggest some sort of storage medium, like a battery or Capacitor bank. this will further assist you in regard to voltage regulation. Just make sure the voltage capacity of either your battery and/or Capacitor bank is not exceeded by the input voltage. The storage medium will also allow a you to have power buffer to keep your devices running, while there is a low wind situation.
One question on the 3rd option, isn't the aim here to say 'charge a battery' on a phone safely, so then how do you connect another battery safely? or doesn't it really care, and is it mainly when the battery is limited compared to the input (so 5V for the phone) that problems may arise… aka. as long as 'he' would say add a large battery or capacitor bank (say 100V, which will never be exceeded by the generator) there isn't really an issue anymore? ps. Really liked your nr.2 that to me read like a genius solution, would be even greater if one could have a software regulated resistance that is controlled by something that can measure the rotation speed of the turbine. That way there can be as little resistance on the breaks during low winds, while higher winds would engage the break.
As a mechanic I would say start with an old style ceiling fan and eliminate 3/4 of the bs because it is already the proper kind of motor with beefer everything. Install a 1 way clutch, install a large capacitor often found in old TV and CRT Monitors, because you installed this and what is coming down the line you would need to install diodes due to flyback voltage, Install your transformer from an old style welder, then another diode, then a AGM Deep Cycle Battery (Blue top would do nicely). Or you could do what the engineer said and make it less efficient, cost more and blow apart your capacitor, fry your transformer and boil over your battery due to flyback voltage and/or the fan spinning backwards. But, trust him he went to school for 4+ years for this kind of stuff and never gets feedback from customers. Unlike us stupid mechanics who have to re-engineer their screw ups to make the customer happy or explain ourselves in court.
@Phil Weatherley The governor idea only nonsense if he plans on never seeing a windstorm big enough to damage the blades. The governor idea is interesting but probably not required, but hardly nonsense.
@Phil Weatherley Your comments use negative jabs like "nonsense" and "worthless" so a lot of people didn't hear a thing you said. Congratulations for showing your insecurities and losing face.
I've learned more about electricity in this 15 minute video than I ever have in school. I've always heard the terms and definitions, but seeing them in practice really glued together my understanding.
Interesting! There's a guy in Far North Queensland who converts induction motors into generators by milling out the rotor and installing magnets. His rectification system is basically identical to yours in architecture. We are using one of his systems at work. The machine is driven by a PTO and the output at full speed exceeds 2000W, at approx 110v. The DC current feeds into a Victron Solar Charge Controller (MPPT), which charges a large battery bank. Replacing a truck alternator, the system has proved more reliable, more powerful, and far more suitable for battery charging. Its also quieter. Thanks for your video!
The ideas, the effort, the investment of your time , energy and money all makes you a valuable human being. I learnt a lot from your video and rate it high
This is awesome! This is what RUclips should be used for. Great effort! Just think of what we could accomplish if we all shared ideas and worked together!
Thank you AutoTechTeacher. I aim to keep my videos real & calm. If it didn't work out, the why-so is interesting also, so other can improve upon/learn from my attempt. If there is an update I will post it!
Hello Rob. So: I looked at your ceiling fan generator videos. Cool: you went deep into it as well! And no, it sure ain't easy. Why did you get tired of my video though? I showed all the many steps that have to be taken, and how the generator and electronics are still not good enough. If I may, I have 2 suggestions for you: measure the output of the inner coils separately from the outer coils. I have not done that. My guess is that using the outer coils only is better than combined, but I am not sure. And, man; your videos are too long! -I saw them all, but while skipping a lot. Keep up the research!
i enjoyed this immensely despite knowing i will never do it myself...i enjoyed the calmness of the voice ,and the lack of thumping music ....very impressive
I must say for your first time that is very impressive. Your demonstration was well presented and truthful. It gives food for thought. Thank you and don't stop. Thinking outside the box is what makes great Inventions. It provides opportunity for someone else. Sorry I have nothing to add as far as technical advice. But I have learned a very old motor that I have been saving is a prime candidate for a generator. What you showed me kept me from wasting my time on the other type of motor.
My father held two masters degrees in electro acoustic engineering and acoustic architectural engineering two minors in electrical engineering and petrochemical engineering it was also ECM reconnaissance Vietnam 1965 to 1968 combat veteran he would disagree as he went to a pass fail as in 4.0 or nothing they drop you School of Engineering called Kresky School of Engineering I'm not sure on the spelling he died when I was about in my 20 years old from agent Orange so yes I think he would disagree he also held seven us patents having to do with omnidirectional spherical speaker enclosures with a Parabolic reflector dish that reduced ear fatigue by 86% over conventional box speaker why is fear simple the inner dynamics of the speaker diaphragm and voice coil works like a piston if you can mitigate shimmy and sway by not having extra sandwich bounce around radically on the diaphragm then you get perfect piston movement that's why it's fear this was confirmed by war department research and development 1946 infrasonic Warfare among other projects dad hacked the war departments classified information using an Atari and a dial-up internet connection in 1986 I was just 5 years old when the van that parked in the boonies that was bright white sat there for hours upon hours apparently wondering how the hell somebody could break into National security files using an Atari and a dial-up connection but he did it...
@@mjolnirswrath23Very interesting read! I mean he would probably disagree because he actually got to apply theory in a practical environment. The problem is the way they teach in university where it's all theoretical and you don't understand because you don't learn applications but instead you just know how to calculate specific questions like a robot.
Aside from the improvements you've already presented in this video, I think a gearbox for the turbine, to generator drive shaft would greatly enhance efficiency. Also, a battery for power storage would help. Lastly, a variable pitch turbine rotor, which would be controlled by an anemometer, would complete the system. Thanks for the video.
@@teezyizeazy6261 it must be, as it turns faster, the direction of the wind changes relatively to the wings. I haven't tried it, but I think it could be done with a linear motion in the axis
take a look at variable pich boat props the shaft is hollow wherein there is a rod interconnected with a flange on each blade that either takes machinework or 3D printer the problem i see is that hub axel and blades on a effetive turbine is already under considerable load why weaken them more for a small gain ,,if you want a good turbine it can be had for about 500 bucks istabreeze 1500 watt 24v dont buy the china stuff as their outout is 1-10 of their rating the blades hub and mousing is okey for parts tough @@teezyizeazy6261
I respect the fact your conclusion was unbiased. You tried an idea and you concluded other alternative approaches might be better.. Look forward to see the alternative options here.
Hello Ehab. Thanks for your comment. Yea: at first I was very positive about using a ceiling fan as base for a DIY wind turbine generator, but I even though I could make a better version now, I now don’t think this is the smartes base to build upon. But it was fun to explore & share, and I am working on a new experiment.
@ROB'S FREE ELECTRICITY DEVICES AND TINKERS "Take it to the limit!" - The Eagles I was thinking about this exact thing as I watched this. I learned about electronics a bit through tinkering and repairs. I have never studied the field. However, my interest is increasing more and more and I feel like a ceiling fan generator can be a good device. My main objective is a the strong strator base and shaft. Personally, I'd redo the coils, magnets, and then aim for a better electronic set up. Someday if I am interested enough, I'll go through all my everyday items to start making random things. Sidenote: Recently, I made a input/output bluetooth adapter that will connect any two 3.5m audio jacks together. One of the two devices connects to your audio source, and the other connects to your audio output (speakers) Both run off of 5v battery or can be USB powered, or DC powered. I prefer DC powered on more permanent set ups, for example, your input would be DC powered, and your output would be battery. Lastly, my input bluetooth adapter is able to do the "broadcast" feature, meaning other devices, like a persons smartphone, could connect to it. This is handy for my home surround sound system, as I can have other friends bluetooth into it. No cables or getting up needed! -Tim
Connect the windings in parallel instead of series. You could connect them so it outputs 25V instead of 50V, and you would not have to waste power in the regulator IC. Connect every other one for half the voltage or every fourth one for 1/4 the voltage.
This is the best way. Fix mechanically from the ground up for the system you have in mind if you want efficiency. Fix afterwards with cheap electronics if you want conveniance.
There's a ceiling fan in my room put in by my late brother when he was living here. It wobbles to much plus I don't like or need it anyway. Thank you for showing me a productive use for it as a generator. Most electronic devices run any where from 3 volts DC to 12 volts DC (lights,radios,portable TVs,cellphones,tablets and computers. This device could power them and/or charged batteries that could power electronic devices. If a device can be plugged into a lighter socket of a car,this generator should be able to power it.
This is a PMA , i made one very similar in my "Doomsday exercise bike generator" video about 1 year ago. i utilized both windings and i got over 110V AC which i powered a shop light. i attached a household outlet to the output which allows me to simply plug in a cellphone charger or battery charger, and use the PMA to charge batteries.
Many thousands of people have had your idea. You actually put it to the test. Thanks for convincing me not to try this with the broken fan I found at the dump!
Replace the linear regulator and dc-dc converter with a solar charge controller with an input voltage capability of 75V, the input is connected to the bridge rectifier output. The solar charge controller output can be used to charge a 12V battery, from this battery you can use your dc-dc converter if necessary to provide a lower voltage such as 5V.
Yes, I agree, that is a better/easier solution. Though inside a solar charge controller are: a rectifier, capacitor, and dc-dc converter... Almost the same, expect for: also containing other smart/necessary electronics, and well balanced.. so yes, your simple solution is better. As for better: I don't want to use the old lead acid batteries anymore. Thus instead Li-ion or LiFePO4. Thanks for comment!
Can be purchased or built is a DC to DC converter that can handle all the power output depending on what you are doing they are at about 80% efficiency, no need for an inefficient solar charger or the resistance regulator. The aim was to charge a phone ? Using just two DC converters would be better than the resistance regulator
SG Buckley's suggestion is the absolute best! Output from the Bridge rectifier, and into the Solar Charge Controller. These are quite cheap on Ebay, and the Solar Charge Controller does everything in one small compact unit, and also gives via the LCD readout the Amps / Volts, state of charge - if connected to a 12v Deep Cycle battery. Some Solar Charge Controllers also incorporate two(2) 5vdc regulated outputs for phone charging. The best 'generator' appears to be the main Motor from a Fisher & Paykel Smart Drive washing Machine. Motor would need reconfiguring. Finally, if you decide to use the F&P Washing Machine Motor, be aware that some of these motors have aluminium wire coils. Avoid these and select copper windings as your first option.
A solar charge controller starts with DC voltage from the PV panels. He is starting with an AC voltage, a better suggestion would be to research the switching diodes and phase shift for DC to AC conversion but that is later on. Stick with the bridge rectifier, and nice work on the magnets and the understanding of how they work with electrical generation. I wonder what this would do attached to a tesla coil?
This video was very helpful. I’ve never taken on a project like this. I’m now more confident I can do the same with this hvac blower. The copper strands are very nice. Thank you so much
Personal opinion though, it would be allot less work getting one of the windmills that's meant for yard art and using it with a pully on a car alternater.
@@oldbatwit5102 use a big sprocket or belt pully on the turbine and a small one on the alternator. You can also use a gear box to further ensure you are getting good rpm
@@starkie1990 Trust me that I am fully familiar with the concept and application of gearing. I don't think you grasp the power loss of gearboxes, pulleys, chains and sprockets etc.
I have Duchenne Muscular Dystrophy and I am 45 years old. I can't move my arms. I love making electronic projects, but my problem is I don't usually have people I can help with this kind of hobby. But I have made some things.
For a solution/cure for that specific type of MS by all means please check out Dr. Niel Riordan PhD.(right here on RUclips for a starter) I then highly suggest that you contact his organization directly. God has given you a keen mind and fine good heart and done likewise for Dr. Riordan. May God continue to bless you both ...together for His honor & glory.
Hi Timothy I live in Mexico city I'm an industrial designer very able with my hands but sometimes lack electronic know_how keep us in mind maybe someday we can help each other!
Wish i lived near ya. Id love to have someone just to bounce ideas off off, much less actual do builds. Im making a water cooled 100w LED work light in an ammo can right now, just for the heck of it. Best of luck! Hope you find some help!!! :D
After you figure out the electroncs more, I suggest you also modify for VWAT. Mount your motor back to the original vertical alignment like it was for a ceiling fan, then mount something like a bike rim to the axel and install vertical blades. This will mean it is omni-directional to wind and will turn in far lighter winds and be less subject to overspeed forces. Since the base is now stationary (omnidirectional) you will not need complicated slip rings to transfer the power or have the cord wrapping around the mount pole.
they only really work i big format , the resistance of the blades going upwind always make them slow but torqey , to make it work a direct drive washing machine moter (rewired in star 24v) and a hefty gearing might be the way to go
This was a great video. Informative and you, the host, are quite charming. I appreciate your straightforward and honest approach. No bluster. No hype. It was great! I'm a fan.
Nice video. My only suggestion might be to keep the inner windings as a regulator. It may be that at a certain speed, your input is at max. At that level, apply braking to regulate the blades at max, for instance, during a storm. It may be used to disable the vanes from spinning. Possibly, this braking energy could be collected as well, using a secondary system that only functions at max wind.
I don't understand why this video got so many dislikes. I thought he did a great job. He tells you right from the beginning that its an experiment, and he explained everything as he did it. Great video! 👍
While I havent watched the vid yet, What I did was use multiple ( to be exact) LM338k voltage regulator controlled outputs feeding a cheap 5 input solar regulator which then fed a bank of 5 deep cycle batteries. The fifth input on the regulator was fed by the cheap Harbor Freight Solar panels. One other thing I did is I mounted a cheap plastic bowel, carefully cut, and fitted, over the hub of the fanwith a rubber "seal" to keap rater out when it rained. this was the hardest part since this seal couldnt induce any drag on the motor.
Ha, yes, or just buy a charge controller ánd a wind turbine and be ready to run in no time! These modern little wind turbines for on boats for example are amazing. But this is a DIY & re-use project. But you are are right and this is my plan: Make a better DIY version 2 of the generator, then focus on the DIY rotor & the turning on a pole, then maybe DIY electronics. Up to that time, a could just use a MPPT charge controller. Everything at once is a bit too much.
@Electrical equipment TAO thank you very much for the information. Many continue to deny the ether although it has been scientifically known to exist for at least a century.
@Electrical equipment TAO no. Good try, but no. I don't think so. I guess were all allowed to differ by our opinions.. While I do believe in a certain type of "Aether" (derived from Latin...) I don't think it's as complicated as you do.
Great teaching video, extreamely interesting. It makes such a difference when a qualified person does a project like this. If you decide to make your own from scratch I'll be looking for that video for sure. Thank you!
My interest in this is much greater than my brain power to understand it. You helped me understand more than others. I believe you are a great teacher.
the coils have shims that raise them away from the core. Why not try to trim those and physically push down on the coils to reduce the gap (@~10:40) ? Very nice video. Your calm voice tone helps :-)
I liked the video...it was very helpful and inspiring. I noticed you had many comments so don’t know if my idea has been used already. The way the fan coils are wired, I believe, is in series. One of the things you could do is wire some of the coils in parallel to help lower the voltage but raise the current. That way when charging a battery, you won’t overshoot the voltage but with higher current the battery will charge the battery faster. I am going to see if I can pick up some ‘trashed’ fan motors and see what I can come up with. Again, good video.
Anything for teaching and learning into the public domain is a gift and a GOD given talent you are blessed to be a blessing a gift isn't a theft good job 😎
I'm not an electrical engineer and don't pretend to be one. However, I see that the center of the ceiling fan stator had larger/smaller holes drilled to balance the difference of weight caused by the wiring used from the factory. When you removed all that useless wire, it offset the once balanced stator. You would need to drill the smaller holes out to the same size as the larger holes to get a balance. Also, the use of neodymium magnets would improve efficiency (which you may or may not have used- it wasn't discussed). A good voltage limiter can be made using op-amp and resistors.
I do not remember having seen this before, but it is really good effort and well done to you, is how we all must learn to walk before running. 10 out of 10.
A very intriguing and informative video, had me glued on to it till the end. You say that you don't have an electronics background, I'd say whatever knowledge that you have is more than that of a beginner. You have a clear understanding of the concepts and know-how of electrical components. Great video. Loved watching it.
I Don’t know much about electricity Giesbert, however your working knowledge is inspirational and educational. Also like you said, there is always room for improvement and fine tuning of good ideas.

You should use an arduino with a hall sensor to read the frequency/speed of the rotor and the secondary coils that you cut off as an magnetic brake. You can collegate the two wires to an relay that is comanded by the arduino. On this way if there are strong winds you can control the max speed with the arduino avoidind on overcharge on the capacitors and dc-dc converters
This is essentially a "Magnetic Governor" Arduino is fairly inexpensive, but a resistor across the second/inner coil would have a steady, and consistent inductive load, kind of like regenerative brakes on a car. Only this won't be charging any batteries, just providing rotational resistance. to prevent over speed, and thus over voltage. The resistor is also cheaper than a micro-controller board, for those budget minded DIY hobbyists. Which based On what I saw in this video, he was trying to do this as cheaply, but reliably as possible. at least it was implied, but not specifically stated.
Projects like these were very common in the 1800’s... just like the explosion of electric vehicles/trams. You literally can’t take the media’s word for anything these days. Keep it up 👍
You haven't elaborated as to the "stronger magnets". Neodymium is the way to go. With respect to reliability of your generator, the use of capacitor with a voltage rating of 50V even though your output can rise above 50V is unwise. The general rule of choosing electronic component specifications is to double the realistic rating, e.g., if the maximum voltage likely to be seen is 50VDC, the capacitor should be at least 100V. Your 50V RMS voltage would hit a peak of about 70 V after being rectified and filtered with the capacitor. So, 50VAC output would lead to 70 VDC. This will kill the capacitor in short order. I suggest a capacitor rated at 100V as the absolute minimum, with 150V being preferable. Mechanically, the bearings concern me. Ceiling fans are meant to be hung from the ceiling and to be installed level. This is to minimize side forces on the bearing in the fan, which aren't designed to take the side forces present in a fan that is installed off-level. Since you are likely to install this in its final location with the shaft of the fan parallel to the ground, I suspect the bearing life will be short as well. That said, I realize that this sort of thing has been done by others. It's not clear if they suffer from a shortened bearing life or if I'm over-dramatizing the effects of installing the fan horizontally.
Neodynium are what are used on these projects. These have ratings and the consideration is the price you would like to spend. Experiance with those. The shiny coating is very brittle and if you bang the square ones together the coating will chip off in sharp shards.
Kinda foolish thing to do, put a lot of time into converting an old, 3/4ths worn out motor for some continuous duty application. Life is too short, if you're bothering at all you should at least get a new, quality motor, or find some other hobby where the outcome was at least worth the time.
@@Standbackforscience Yeah man sometimes we just do things purely to see if we can and to see what happens. We humans love cause and effect. We love testing it just to see what will happen it ads a dimension of exitement to life. Slap a cop and just enjoy the thrill of the moment. If any one asks just say it was a social experiment.
Having built several wind turbines over the last 40 some odd years, don't sell yourself short my friend. You took a product that someone obviously didn't want and found another use for it. That's what we creative engineers do. You were definitely on the right track with your switching regulator setup and you should have dumped the output into a storage battery and then you could have used that to drive an inverter to produce the AC voltage whichever is standard in your country either 110-120 vac or 220-240 vac depending on where you live. You could have then easily charged your phone or any other USB device for that matter! I'm a HAM operator and I fly RC models, and with the advent of inexpensive brushless motors, building wind turbines just became a whole lot simpler, especially when you look at some of the larger motor sizes that will easily produce 90 to 160 amp of current. Use your imagination my friend! Vertical Axis Wind Turbines are extremely easy to construct and can easily be mounted a lot higher up and don't produce the noise that conventional bladed models do. Try using the rotor from an old squirrel cage fan. Best of luck to you !
Great video. Never thought about it before, but I wonder if the inner coil you removed could be used as a brake in the event the wind wanted to spin the blades too quickly. Seems like slowing the blades might be better than burning off the extra electricity produced... although I have no idea how hot the coils might get trying to fight mother nature. Fun project!
Yes that is a good idea: keep the inner coil (=easier too) and use it for A) power and B) a brake for when windspeeds are too high. If it is still turning too fast, the main coils can also act as a brake. And next things could get hot.. It needs electronics and software really. Arduino project for small wind turbine anyone?
Having a battery to charge would be good. The power can be stored & regulated slightly this way. I used to experiment some time back. The wear seemed more a problem. There are better options as you mentioned which I did not have then. I will get to it someday & record it too. Thank you for it.
This is the type of video that inspires people to explore engineering as a possible profession. Even if it only serves this purpose, it is a tremendous success and well worth the time/effort it took to create.
I can't get over what a great video this is of a failure. Great work seeing it all the way to the end. Knowing what not to do saved me from going down that path.
There is a way to use an induction machine as a generator, namely by connecting a capacitor in parallel with it to generate the reactive current which will magnetise the airgap. Many old wind turbines use this. Maybe you could even use the inner coils for this purpose: connect a capacitor to those. I like the idea of using this fan because of its low rpm. Great idea. Why not use the original winding, accept that it's made to generate high voltage and chop that down to a value acceptable to you? It would generate the same power as lower voltage with higher current.
I've done 3 of these. Here is the secret. Don't put north on one coil and south on the next. Use smaller magnets and put 2 magnets on each coil BUT put them ns ...sn ...ns...sn. The other way is to turn the magnets on their side the same way south facing south and north facing north. This doubles the power and spins easier. Try it. You will be amazed. I'm lighting 45 watt bulbs AC with slight breezes.
That is an interesting and apparently good idea, to place the magnets like that. And you don't close the gap (makes it easier). Did you use a 120V or 240V model? Problem with possibly both (I have only 240V) is the output voltage can go too high. What voltage do you get out of yours? And how do you get it down to a practical level? Thanks for sharing!
i like your idea, but a few years ago i wanted to make a turbine. My thought was similar to yours but i went with a car alternator to convert. not a lot was needed to make it work and i was able (at the time) to purchase cheap old alternators from a auto wreckers salvage shop. it cost me about $15 for an alternator of a 6 cylinder car. once i had wired the alternator and added fan blades i made from sheet aluminium, my generator was able to charge a car battery in a day from dead flat. my fan was only 80 cm in diameter and the whole thing cost me me under a hundred dollars once all costs were counted (excluding the battery). my plan was to have a bank of 10 x 24 volt truck batteries in line to produce 240 volts as my mains power to my house is 240 volt. i was going to ad solar panels to the charging process to double the charge charge rate, and eventually set the battery bank under the house. i could not complete the hobby as i became injured and unable to continue. but to me, in my head, it was a breakthrough for suburban free energy. funnily enough, the solar thing took off some years after and i believe now it will be cheaper to have professional companies to supply and install solar panels and a Tesla battery. but i had fun back in the day thinking i was going to be rich with my design of wind and solar energy for individual houses. ironically, all my neighbors have professionally installed solar panels and free electricity, while i am still connected to the power company and paying the HIGHEST electricity prices in the world. Yes, i am in Australia, where elderly ppl die each year from the cold and the heat as they cant afford to use electricity. it is 5 times higher to buy electricity here than europe or asia. hence, i wanted to build a home made free power generator (Solar and wind)
Australia has plenty of clean coal and uranium and a ban on nuclear power. We closed down coal powered stations, could have converted the to nuclear by replacing steam generated by coal fired burners with steam generated by new gen nuclear power. The power generators could have been utilised and not destroyed. Alas, the Green Party has had too much influence and scaremongering due to the major parties requiring their coalition to remain in power and remain too short sighted to realise that their appeasement hurts average working Australians for a goal that will do nothing toward Global Warming as what we produce is but a mosquito ‘s fart in a cyclone. We had one bushfire here a few years back, started by lightning, that emitted enough carbon dioxide in 1 week as all the coal fired power stations and vehicles in Australia emitted in 5 years.
FUCK RUclips no problems there as solar batteries only produce DC as well. All you do is generate a sine wave at 50 hz and amplify to 240v through parallel current limiters and a transformer. Switch the current limiters on and off according to required power. This is done commercially through the solar panel inverters anyway
@@AJHyland63 "Clean coal" is a myth. It doesn't exist. Anytime you burn anything made of carbon, you are taking that "stored" carbon and putting it into the atmosphere. At least you understand that this action contributes to global warming. Just because a brush fire (unverified amount by the way) contributes to global warming dosen't mean coal fired power plants are a good thing. As far as nuclear power plants go, we've all seen what a fucking disaster those things can turn into. And no insurance company in the world will insure them. Think about that.
Hey man I really appreciate people like you and love the content, even if it wasn’t as efficient as we hoped it was still a learning experience especially for me so I appreciate the potential life saving knowledge.
A dc motor with permanent magnets is cheap, and requires none of the major engineering... not as much fun, perhaps, but if your goal is a working 12 volt system, that is the easiest way... it can be regulated by a automobile 12 volt regulator for cars that use a generator, rather than an alternator... Bosh for the old VWs is my personal preference... they can be used with either wind or water to generate electricity all day and night... That being said, I think the effort was a great learning experience... that is how new technology comes about. . Excellent video sir
sir; Please don’t kick yourself. In my case this is exactly what I want to do. Your instructions and explanation was fantastic. I wish my professor at the university did as good of a job as you.
@@saranjimable One challenge with the alternator is that it must spin relatively quickly, so you would need some drive system (belt and pulleys, etc..) to increase the shaft speed relative the wind turbine part, which can eat some of the energy. By starting with a motor that has many poles (the hoverboard motor looked interesting) you can produce more power at lower RPM, potentially eliminating any drive line parts and therefore the parasitic losses that goes with them, potentially generating more electrical power for the same amount of wind.
It has always bewildered me why, when someone takes the trouble to share their experience and knowledge in an open way, expressing what they are learning, inviting comment and suggestions so they and others can learn, is given dislikes and negative and demeaning comments. Why is that. Negative suggestions that are disguised as personal attacks on people who are simply trying to establish a relationship with like minded people do not deserve this and it accomplish nothing but to close people off. I was an engineering manager for many years. In my world, there were no such thing as bad ideas because whatever was put forward became a stepping stone to something better. These negative type people very seldom contributed anything of worth to projects. On the other hand, cooperation, contribution, respect, flexibility and the like always lead to better outcomes and a sense of accomplishment for Everyone. Thank you for sharing! Excellent!
Turbines can spin too fast in high winds and unloaded. It is potentially dangerous to have a load shut off in high wind just because the voltage is high.
Yeah, it would have been nice to see the feasibility of using those inner coils used as part of a braking system to stop the turbine from flying apart... maybe another video, or explanation on why that isn't a good idea?
@@pfeerick Not a bad idea. Connect a voltage dividing network of resistors to the output of the rectifyed and smoothed DC before the dc to dc converter. One 3k and one 21k with the 21k connected to + and the 3k connected to - and the middle is fed to a comparator. The comparator is powered by 5v from the dc to dc converter. A 3v reference voltage is made with a 100k resistor and zener diode. Then if the voltage rises to 24v, the 4k resistor drops 21v and the 1k drops 3v sending that 3v to the comparator to compare against the reference voltage. If the voltage from the voltage dividing network goes higher than the comparator, the comparator turns on switching a relay that dumps that power into a nichrome wire dissipating the power as heat. All that's needed is a few turns of thick wire on the stator. For that coil. So now if the smoothed and recitified DC goes over 24v, the load dump coil feeds power to the load dump. The turbine will not spin any faster than when it puts out about 25-26V
The time I spent in Iowa, gave me an opportunity to sit in a dinner when a group of wind turbine company techs sat down at the next table. Conversation turned to the inner working of a commercial wind turbine. (Talking shop) They explained the largest expense inside the box is the transmission system. While some use electric braking to stabilize rotor speed, but variable pitch blades, hydraulically controlled shifting to the generator. So as wind speed increased, the calculated load increased the gear selection to add 3 sets of windings on the generator. Each produced a load to the rotor, but also increased output wattage with wind speed. Servicing the hydraulics, bearing blocks, electronics including sensors were most of the maintenance they had to perform. Then the rotor housing turns 360 degrees on a captured roller bearing system and it alone required constant maintenance. They estimate that 14 of 100 wind turbines are down at any given time due to service, waiting on parts (Most from Germany) and other issues. They have wind farms all over Iowa and now Starting in NE Nebraska in 2021 after study. Wind still produces only less than 0.2% of all the power produced in the US as of 2018. So much work to get so little with too much effort.
Could you arrange the magnets in a Halbach array to double the magnetic flux? How does mounting it as a horizontal wind turbine affect the bearings given that ceiling fans are vertical axis? If the induction motor was already on an AC supply, the speed would be fixed but any wind power would still be added to the AC grid. However should there not be enough wind, the induction motor would pull power from the grid. Unfortunately inverters don't work very well to provide the initial power source, you pretty much need actual alternators controlled by a regulated mechanical prime mover to regulate the voltage and frequency and of course an actual load. This is actually how power plants work on the grid so induction motors without magnets can be used to generate power just not without an already operating grid.
For everyone who brought up the problems of a horizontal-axis wind turbine...Google or search on RUclips to find vertical-axis wind turbines! Both designs exist.
@@LiveHappy76 Far less efficient, and the most common designs will not start rotating on their own from a dead stop. For the dynamo you're much better using one of the many self-built designs than with putting almost the same amount of effort into converting an existing device into a lesser machine.
I had been contemplating this project for a while. Thanks for saving me the trouble of seeing if it works. Looks like it was a fun attempt nonetheless! Good job Giesbert.
Enjoyed video. If you want to learn more watch Gerard Morins videos. These work great. The best motors in my experience are the Scotter motors and the Wheel chair Motors the Torque is amazing in the wheelchair motor.Also the washing machine motors are what Mr Morin uses.Gez in the UK
Halbach array will give you almost 2x as much magnetic force in the direction of the strator. Also to regulate the over voltage store it or use it but don't let it heat the coils or it won't last long.
I found your alteration interesting. It reminds me of what many of our Bushmen do here in Alaska. Here we get a GE or Chevy alternator. It is fasted to a stand. Sometimes a home built tower. Sometimes a post. Like a flag poll. Only it is flanged so you can bolt onto the top a windmill. On the shaft of your wind blades is a corresponding pully so you can connect the rotation of the windmill to a GE Alternator by an appropriate automotive fan belt. This transfers wind into mechanical energy via the belt & pullies. In turn the mechanical energy is converted into electrical energy by the alternator. In a GE Alternator there is an internal bank of diodes. These diodes convert the 130’ish volts of a typical low end alternator or about 160’ish to 190’ish ac volts of a high output alternator into useable 12 volt via the diode bank. The only maintenance is changing the brushes inside the alternator ever so often. Also, if one of the diodes open ( think like turning off the light switch ) then you will have to replace the diode bank, but this is unusual. This is an easy setup after your tower or post is set. It is also low typically low maintenance. Now you can use a Ford Alternator or even an old cars generator to do the same thing; however, you will need some additional components to regulate the out-put of voltage. In comparison of these two options. The GE Alternator is easer to hook up to a battery bank for simple lighting. With the Ford Alternator you can get a different independent regulator rather than the automotive ones. So long as it is compatible. This will require a better set-up, but the extra effort yields more power output. Build it strong to service a wind storm and both become virtually maintenance free. Cheers everyone. I did like this video though, because I have often wondered about what this man did. Now I know. Thank you for this demonstration.
Treadmills have variable-speed dc motors, not generators. I imagine that's a good basis for a generator, but I dunno for sure. I'm looking for an article on adapting a treadmill motor to my bandsaw and my drill press...
The wire size was chosen to run at 120volts and less than 0.5 amp, with some resistive loss in the wire. So if you ever want to get 60 watts out, the voktage would be high (120v) and the wire would be lossy... So, yes, that wire is too thin!
Oh, the coil makes AC. It has no "commutator" on the spinning shaft, or electronic parts "rectifier" to change it to DC. We can add the rectifier if we want to. Specifically a "full-wave bridge", which is a square of 4 diodes.

Thanks and I agree, but how can you be sure I am not a zombie? (really, have you seen the state I am in?) Not all zombies are bad. (some are preserved well).
Alexander Gray II so in lieu of an apocalypse EE’s are worth ‘bout tree fidy.
I'll steal an actual wind generator, and probably eat the engineer.
Or worth their weight in copper.
a word of thanks to you. never sell yourself short. as many of us here watched your presentation it was well understood, not boring at all. you may not believe it your system works as well as any other devices out there. keep sharing your knowledge with the world, we are listening. there will always be room for improvement in anything man does. do not stop,
Hello Giesbert Nijhuis: I've been an electrical engineer for 20 years, And I have some advise for improving the function and efficiency of your ceiling fan turned wind turbine.
1st: I like to say you have a firm foundation for creating your own free energy device. I believe that you're on the right track with this project.
2nd: I think that You needed to Keep those inner coils so that you could use them as a magnetic governor, to prevent over speeding the turbine, and thus keeping the raw input voltage from getting too high. "A simple 10 Mega-ohm power resistor" across the inner coils, would provide a semi-regulated load. and thus cause enough rotational resistance, to prevent an over speed event. A wire wound Variable resistor, or a rheostat used, instead of a straight resistor, would allow you to adjust the governor strength by adjusting the the inductive current flow caused by your magnets acting on the inner coils. Changing the resistance will in turn change the inductive load. allowing the turbine to spin faster or slower, depending on the load resistance on the inner coils. This is how to keep this wind turbine from frying your step down circuit(s) which will fail before anything connected to it will. Your power regulator, and DC converter are the weak links here. But if you can regulate the raw input voltage from your coils before it even gets to your power circuits, that weakness will be a non-issue.
3rd and finally: I would suggest some sort of storage medium, like a battery or Capacitor bank. this will further assist you in regard to voltage regulation. Just make sure the voltage capacity of either your battery and/or Capacitor bank is not exceeded by the input voltage. The storage medium will also allow a you to have power buffer to keep your devices running, while there is a low wind situation.
One question on the 3rd option, isn't the aim here to say 'charge a battery' on a phone safely, so then how do you connect another battery safely? or doesn't it really care, and is it mainly when the battery is limited compared to the input (so 5V for the phone) that problems may arise… aka. as long as 'he' would say add a large battery or capacitor bank (say 100V, which will never be exceeded by the generator) there isn't really an issue anymore?
ps. Really liked your nr.2 that to me read like a genius solution, would be even greater if one could have a software regulated resistance that is controlled by something that can measure the rotation speed of the turbine. That way there can be as little resistance on the breaks during low winds, while higher winds would engage the break.
Great question
As a mechanic I would say start with an old style ceiling fan and eliminate 3/4 of the bs because it is already the proper kind of motor with beefer everything. Install a 1 way clutch, install a large capacitor often found in old TV and CRT Monitors, because you installed this and what is coming down the line you would need to install diodes due to flyback voltage, Install your transformer from an old style welder, then another diode, then a AGM Deep Cycle Battery (Blue top would do nicely). Or you could do what the engineer said and make it less efficient, cost more and blow apart your capacitor, fry your transformer and boil over your battery due to flyback voltage and/or the fan spinning backwards. But, trust him he went to school for 4+ years for this kind of stuff and never gets feedback from customers. Unlike us stupid mechanics who have to re-engineer their screw ups to make the customer happy or explain ourselves in court.
@Phil Weatherley The governor idea only nonsense if he plans on never seeing a windstorm big enough to damage the blades. The governor idea is interesting but probably not required, but hardly nonsense.
@Phil Weatherley Your comments use negative jabs like "nonsense" and "worthless" so a lot of people didn't hear a thing you said. Congratulations for showing your insecurities and losing face.
I've learned more about electricity in this 15 minute video than I ever have in school. I've always heard the terms and definitions, but seeing them in practice really glued together my understanding.
Interesting! There's a guy in Far North Queensland who converts induction motors into generators by milling out the rotor and installing magnets. His rectification system is basically identical to yours in architecture. We are using one of his systems at work. The machine is driven by a PTO and the output at full speed exceeds 2000W, at approx 110v. The DC current feeds into a Victron Solar Charge Controller (MPPT), which charges a large battery bank. Replacing a truck alternator, the system has proved more reliable, more powerful, and far more suitable for battery charging. Its also quieter. Thanks for your video!
Although you weren't satisfied with your final results, you made a very useful presentation here. Kudos!
The ideas, the effort, the investment of your time , energy and money all makes you a valuable human being. I learnt a lot from your video and rate it high
It's basic EE knowledge that motors make bad generators. Good presentation and demonstration as to why.
This is awesome! This is what RUclips should be used for. Great effort! Just think of what we could accomplish if we all shared ideas and worked together!
Now the energy companies are ripping us off, looks like these videos will be more useful.

Hello Rob. So: I looked at your ceiling fan generator videos. Cool: you went deep into it as well! And no, it sure ain't easy. Why did you get tired of my video though? I showed all the many steps that have to be taken, and how the generator and electronics are still not good enough. If I may, I have 2 suggestions for you: measure the output of the inner coils separately from the outer coils. I have not done that. My guess is that using the outer coils only is better than combined, but I am not sure. And, man; your videos are too long! -I saw them all, but while skipping a lot. Keep up the research!
5 years ago and i can say this is one the best videos i came across on RUclips. Perfect Explanation by the way.👍
i enjoyed this immensely despite knowing i will never do it myself...i enjoyed the calmness of the voice ,and the lack of thumping music ....very impressive
I must say for your first time that is very impressive. Your demonstration was well presented and truthful. It gives food for thought. Thank you and don't stop. Thinking outside the box is what makes great Inventions. It provides opportunity for someone else. Sorry I have nothing to add as far as technical advice. But I have learned a very old motor that I have been saving is a prime candidate for a generator. What you showed me kept me from wasting my time on the other type of motor.

@@mjolnirswrath23Very interesting read! I mean he would probably disagree because he actually got to apply theory in a practical environment. The problem is the way they teach in university where it's all theoretical and you don't understand because you don't learn applications but instead you just know how to calculate specific questions like a robot.
Aside from the improvements you've already presented in this video, I think a gearbox for the turbine, to generator drive shaft would greatly enhance efficiency. Also, a battery for power storage would help. Lastly, a variable pitch turbine rotor, which would be controlled by an anemometer, would complete the system. Thanks for the video.
Can you do a video on the variable pitch turbine rotor please?
Is that to automatically change the angle of the blades?
@@teezyizeazy6261 it must be, as it turns faster, the direction of the wind changes relatively to the wings. I haven't tried it, but I think it could be done with a linear motion in the axis

Hello Ehab. Thanks for your comment. Yea: at first I was very positive about using a ceiling fan as base for a DIY wind turbine generator, but I even though I could make a better version now, I now don’t think this is the smartes base to build upon. But it was fun to explore & share, and I am working on a new experiment.

"Take it to the limit!" - The Eagles
I was thinking about this exact thing as I watched this. I learned about electronics a bit through tinkering and repairs. I have never studied the field. However, my interest is increasing more and more and I feel like a ceiling fan generator can be a good device. My main objective is a the strong strator base and shaft.
Personally, I'd redo the coils, magnets, and then aim for a better electronic set up. Someday if I am interested enough, I'll go through all my everyday items to start making random things.
Sidenote: Recently, I made a input/output bluetooth adapter that will connect any two 3.5m audio jacks together. One of the two devices connects to your audio source, and the other connects to your audio output (speakers) Both run off of 5v battery or can be USB powered, or DC powered. I prefer DC powered on more permanent set ups, for example, your input would be DC powered, and your output would be battery. Lastly, my input bluetooth adapter is able to do the "broadcast" feature, meaning other devices, like a persons smartphone, could connect to it. This is handy for my home surround sound system, as I can have other friends bluetooth into it. No cables or getting up needed!

Don't sell yourself short. You know how to improve on designs, this information is very valuable. Thanks for the information!
💯 on your comment 🤔🙋😎.
Outstanding video. The substance, pacing, and tone are spot on. Well done!
Connect the windings in parallel instead of series. You could connect them so it outputs 25V instead of 50V, and you would not have to waste power in the regulator IC. Connect every other one for half the voltage or every fourth one for 1/4 the voltage.
This is the best way. Fix mechanically from the ground up for the system you have in mind if you want efficiency. Fix afterwards with cheap electronics if you want conveniance.
I'm a "fan" of ElectroBoom, I'm here to thank you for using the FULL BRIDGE RECTIFIER :)

Beats the try-on hauls which usually clog my feed. 4 million views restores my hope for humanity.
There's a ceiling fan in my room put in by my late brother when he was living here. It wobbles to much plus I don't like or need it anyway. Thank you for showing me a productive use for it as a generator. Most electronic devices run any where from 3 volts DC to 12 volts DC (lights,radios,portable TVs,cellphones,tablets and computers. This device could power them and/or charged batteries that could power electronic devices. If a device can be plugged into a lighter socket of a car,this generator should be able to power it.
This is a PMA , i made one very similar in my "Doomsday exercise bike generator" video about 1 year ago. i utilized both windings and i got over 110V AC which i powered a shop light. i attached a household outlet to the output which allows me to simply plug in a cellphone charger or battery charger, and use the PMA to charge batteries.
Many thousands of people have had your idea. You actually put it to the test. Thanks for convincing me not to try this with the broken fan I found at the dump!
Replace the linear regulator and dc-dc converter with a solar charge controller with an input voltage capability of 75V, the input is connected to the bridge rectifier output. The solar charge controller output can be used to charge a 12V battery, from this battery you can use your dc-dc converter if necessary to provide a lower voltage such as 5V.
Yes, I agree, that is a better/easier solution. Though inside a solar charge controller are: a rectifier, capacitor, and dc-dc converter... Almost the same, expect for: also containing other smart/necessary electronics, and well balanced.. so yes, your simple solution is better. As for better: I don't want to use the old lead acid batteries anymore. Thus instead Li-ion or LiFePO4. Thanks for comment!
Can be purchased or built is a DC to DC converter that can handle all the power output depending on what you are doing they are at about 80% efficiency, no need for an inefficient solar charger or the resistance regulator. The aim was to charge a phone ? Using just two DC converters would be better than the resistance regulator
SG Buckley's suggestion is the absolute best! Output from the Bridge rectifier, and into the Solar Charge Controller. These are quite cheap on Ebay, and the Solar Charge Controller does everything in one small compact unit, and also gives via the LCD readout the Amps / Volts, state of charge - if connected to a 12v Deep Cycle battery. Some Solar Charge Controllers also incorporate two(2) 5vdc regulated outputs for phone charging. The best 'generator' appears to be the main Motor from a Fisher & Paykel Smart Drive washing Machine. Motor would need reconfiguring. Finally, if you decide to use the F&P Washing Machine Motor, be aware that some of these motors have aluminium wire coils. Avoid these and select copper windings as your first option.
I would like to see that setup done, it sounds interesting and MAYBE doable for us non-electrically inclined. Please do a video of it.
A solar charge controller starts with DC voltage from the PV panels. He is starting with an AC voltage, a better suggestion would be to research the switching diodes and phase shift for DC to AC conversion but that is later on.
Stick with the bridge rectifier, and nice work on the magnets and the understanding of how they work with electrical generation. I wonder what this would do attached to a tesla coil?
This video was very helpful. I’ve never taken on a project like this. I’m now more confident I can do the same with this hvac blower. The copper strands are very nice. Thank you so much
Your mind and expressive gift are great. I am Canadian. Also a Power Engineer for 30 years. 😎👍
Convert the generated electricity into DC to charge a preferably good size battery. Then use a power inverter to power home electronics.
Personal opinion though, it would be allot less work getting one of the windmills that's meant for yard art and using it with a pully on a car alternater.
@@starkie1990 Car alternators need a lot of wind power to turn them. Pulleys waste power.
@@oldbatwit5102 use a big sprocket or belt pully on the turbine and a small one on the alternator. You can also use a gear box to further ensure you are getting good rpm

After you figure out the electroncs more, I suggest you also modify for VWAT. Mount your motor back to the original vertical alignment like it was for a ceiling fan, then mount something like a bike rim to the axel and install vertical blades. This will mean it is omni-directional to wind and will turn in far lighter winds and be less subject to overspeed forces. Since the base is now stationary (omnidirectional) you will not need complicated slip rings to transfer the power or have the cord wrapping around the mount pole.
Great idea
When you say vertical, do you mean the axis of rotation?
they only really work i big format , the resistance of the blades going upwind always make them slow but torqey , to make it work a direct drive washing machine moter (rewired in star 24v) and a hefty gearing might be the way to go
How about keeping the inner windings for the regulator to dump excess power into providing a brake when the wind blows to hard.
that's why electric cars get better mileage in the city than the highway. nice!
Good job sir
You explained things clearly
I really appreciate how you criticize your own project only few people will do that.
This was a great video. Informative and you, the host, are quite charming. I appreciate your straightforward and honest approach. No bluster. No hype. It was great! I'm a fan.
I too would like to compliment your video production skills. It moved right along, had great graphics and was very instructional.
Nice video. My only suggestion might be to keep the inner windings as a regulator. It may be that at a certain speed, your input is at max. At that level, apply braking to regulate the blades at max, for instance, during a storm. It may be used to disable the vanes from spinning. Possibly, this braking energy could be collected as well, using a secondary system that only functions at max wind.
I don't understand why this video got so many dislikes. I thought he did a great job. He tells you right from the beginning that its an experiment, and he explained everything as he did it. Great video! 👍
At the end you asked for suggestions about improving the electronics. I have a suggestion. Use a MPPT charge controller and done!
While I havent watched the vid yet, What I did was use multiple ( to be exact) LM338k voltage regulator controlled outputs feeding a cheap 5 input solar regulator which then fed a bank of 5 deep cycle batteries. The fifth input on the regulator was fed by the cheap Harbor Freight Solar panels. One other thing I did is I mounted a cheap plastic bowel, carefully cut, and fitted, over the hub of the fanwith a rubber "seal" to keap rater out when it rained. this was the hardest part since this seal couldnt induce any drag on the motor.
Ha, yes, or just buy a charge controller ánd a wind turbine and be ready to run in no time! These modern little wind turbines for on boats for example are amazing. But this is a DIY & re-use project. But you are are right and this is my plan: Make a better DIY version 2 of the generator, then focus on the DIY rotor & the turning on a pole, then maybe DIY electronics. Up to that time, a could just use a MPPT charge controller. Everything at once is a bit too much.

Magnets Make Me Merry!
I liked the video...it was very helpful and inspiring. I noticed you had many comments so don’t know if my idea has been used already. The way the fan coils are wired, I believe, is in series. One of the things you could do is wire some of the coils in parallel to help lower the voltage but raise the current. That way when charging a battery, you won’t overshoot the voltage but with higher current the battery will charge the battery faster.
I am going to see if I can pick up some ‘trashed’ fan motors and see what I can come up with. Again, good video.
Anything for teaching and learning into the public domain is a gift and a GOD given talent you are blessed to be a blessing a gift isn't a theft good job 😎

Nicely done video on an interesting topic. Speaker was clear and well-spoken. Thanks for the diligent effort.
I'm not an electrical engineer and don't pretend to be one. However, I see that the center of the ceiling fan stator had larger/smaller holes drilled to balance the difference of weight caused by the wiring used from the factory. When you removed all that useless wire, it offset the once balanced stator. You would need to drill the smaller holes out to the same size as the larger holes to get a balance. Also, the use of neodymium magnets would improve efficiency (which you may or may not have used- it wasn't discussed). A good voltage limiter can be made using op-amp and resistors.
That part doesn't spin, no need to be properly weighted
I do not remember having seen this before, but it is really good effort and well done to you, is how we all must learn to walk before running. 10 out of 10.

A very intriguing and informative video, had me glued on to it till the end. You say that you don't have an electronics background, I'd say whatever knowledge that you have is more than that of a beginner. You have a clear understanding of the concepts and know-how of electrical components. Great video. Loved watching it.
I Don’t know much about electricity Giesbert, however your working knowledge is inspirational and educational. Also like you said, there is always room for improvement and fine tuning of good ideas.

You should use an arduino with a hall sensor to read the frequency/speed of the rotor and the secondary coils that you cut off as an magnetic brake. You can collegate the two wires to an relay that is comanded by the arduino. On this way if there are strong winds you can control the max speed with the arduino avoidind on overcharge on the capacitors and dc-dc converters
Wow that's an great idea using one of the windings for control speed.
This is essentially a "Magnetic Governor" Arduino is fairly inexpensive, but a resistor across the second/inner coil would have a steady, and consistent inductive load, kind of like regenerative brakes on a car. Only this won't be charging any batteries, just providing rotational resistance. to prevent over speed, and thus over voltage. The resistor is also cheaper than a micro-controller board, for those budget minded DIY hobbyists. Which based On what I saw in this video, he was trying to do this as cheaply, but reliably as possible. at least it was implied, but not specifically stated.
@@alien200049655 Isn't that like dynamic breaking on a locomotive?
Projects like these were very common in the 1800’s... just like the explosion of electric vehicles/trams. You literally can’t take the media’s word for anything these days. Keep it up 👍
You haven't elaborated as to the "stronger magnets". Neodymium is the way to go. With respect to reliability of your generator, the use of capacitor with a voltage rating of 50V even though your output can rise above 50V is unwise. The general rule of choosing electronic component specifications is to double the realistic rating, e.g., if the maximum voltage likely to be seen is 50VDC, the capacitor should be at least 100V. Your 50V RMS voltage would hit a peak of about 70 V after being rectified and filtered with the capacitor. So, 50VAC output would lead to 70 VDC. This will kill the capacitor in short order. I suggest a capacitor rated at 100V as the absolute minimum, with 150V being preferable.
Mechanically, the bearings concern me. Ceiling fans are meant to be hung from the ceiling and to be installed level. This is to minimize side forces on the bearing in the fan, which aren't designed to take the side forces present in a fan that is installed off-level. Since you are likely to install this in its final location with the shaft of the fan parallel to the ground, I suspect the bearing life will be short as well.
That said, I realize that this sort of thing has been done by others. It's not clear if they suffer from a shortened bearing life or if I'm over-dramatizing the effects of installing the fan horizontally.
Neodynium are what are used on these projects. These have ratings and the consideration is the price you would like to spend. Experiance with those. The shiny coating is very brittle and if you bang the square ones together the coating will chip off in sharp shards.
In the US, you can get these super magnets at your local hobby shop. Mine has them.
I heard some washing machines were built with permanent magnet motors. These motors might work nicely.
yeah there are videos on this topic, people using old washing machine motors for hydro elec
Kinda foolish thing to do, put a lot of time into converting an old, 3/4ths worn out motor for some continuous duty application. Life is too short, if you're bothering at all you should at least get a new, quality motor, or find some other hobby where the outcome was at least worth the time.
@@stinkycheese804 you really are a sticky cheese. Just like your opinion.

Having built several wind turbines over the last 40 some odd years, don't sell yourself short my friend. You took
a product that someone obviously didn't want and found another use for it. That's what we creative engineers
do. You were definitely on the right track with your switching regulator setup and you should have dumped the
output into a storage battery and then you could have used that to drive an inverter to produce the AC voltage
whichever is standard in your country either 110-120 vac or 220-240 vac depending on where you live. You
could have then easily charged your phone or any other USB device for that matter!
I'm a HAM operator and I fly RC models, and with the advent of inexpensive brushless motors, building wind
turbines just became a whole lot simpler, especially when you look at some of the larger motor sizes that will
easily produce 90 to 160 amp of current. Use your imagination my friend! Vertical Axis Wind Turbines are
extremely easy to construct and can easily be mounted a lot higher up and don't produce the noise that
conventional bladed models do. Try using the rotor from an old squirrel cage fan.
Best of luck to you !
The DC to DC converter with the regulator: WHOA~! Thanks for sharing your big brain with us, Jason.
Wow, this is the kind of detailed instruction in electricity that I've been needing. AND a great wind power DIY! Thanks
Great video. Never thought about it before, but I wonder if the inner coil you removed could be used as a brake in the event the wind wanted to spin the blades too quickly. Seems like slowing the blades might be better than burning off the extra electricity produced... although I have no idea how hot the coils might get trying to fight mother nature. Fun project!
Yes that is a good idea: keep the inner coil (=easier too) and use it for A) power and B) a brake for when windspeeds are too high. If it is still turning too fast, the main coils can also act as a brake. And next things could get hot.. It needs electronics and software really. Arduino project for small wind turbine anyone?
@@GiesbertNijhuisI've never heard L.E.Ds pronounced your way that's weird
a dump load would do ,also the a30 voltage relay along with a solid state relay is a decent way of controlling a turbine @@GiesbertNijhuis
Having a battery to charge would be good. The power can be stored & regulated slightly this way. I used to experiment some time back. The wear seemed more a problem. There are better options as you mentioned which I did not have then. I will get to it someday & record it too. Thank you for it.
Try converting a brush-less motor from an exercise treadmill. They are readily available and much more robust than the motor from a ceiling fan.
Mo expensive though
Tek Smash Depending where you live there are lots for free available. People can't sell them so,they are plentiful
top drawer all the way. not a fake video. just straight talk by a smart well spoken man. thanks
Great work. You can feed the AC to some kind of battery charging circuit and then use stable DC from the battery.
This is the type of video that inspires people to explore engineering as a possible profession. Even if it only serves this purpose, it is a tremendous success and well worth the time/effort it took to create.
I can't get over what a great video this is of a failure. Great work seeing it all the way to the end. Knowing what not to do saved me from going down that path.
There is a way to use an induction machine as a generator, namely by connecting a capacitor in parallel with it to generate the reactive current which will magnetise the airgap. Many old wind turbines use this. Maybe you could even use the inner coils for this purpose: connect a capacitor to those.
I like the idea of using this fan because of its low rpm. Great idea.
Why not use the original winding, accept that it's made to generate high voltage and chop that down to a value acceptable to you? It would generate the same power as lower voltage with higher current.
This was your first electronic experiment? Awesome.
I've done 3 of these. Here is the secret. Don't put north on one coil and south on the next. Use smaller magnets and put 2 magnets on each coil BUT put them ns ...sn ...ns...sn. The other way is to turn the magnets on their side the same way south facing south and north facing north. This doubles the power and spins easier. Try it. You will be amazed. I'm lighting 45 watt bulbs AC with slight breezes.
I can send you video. GIVE me your text number
That is an interesting and apparently good idea, to place the magnets like that. And you don't close the gap (makes it easier). Did you use a 120V or 240V model? Problem with possibly both (I have only 240V) is the output voltage can go too high. What voltage do you get out of yours? And how do you get it down to a practical level? Thanks for sharing!
i like your idea, but a few years ago i wanted to make a turbine. My thought was similar to yours but i went with a car alternator to convert. not a lot was needed to make it work and i was able (at the time) to purchase cheap old alternators from a auto wreckers salvage shop. it cost me about $15 for an alternator of a 6 cylinder car. once i had wired the alternator and added fan blades i made from sheet aluminium, my generator was able to charge a car battery in a day from dead flat. my fan was only 80 cm in diameter and the whole thing cost me me under a hundred dollars once all costs were counted (excluding the battery). my plan was to have a bank of 10 x 24 volt truck batteries in line to produce 240 volts as my mains power to my house is 240 volt. i was going to ad solar panels to the charging process to double the charge charge rate, and eventually set the battery bank under the house. i could not complete the hobby as i became injured and unable to continue. but to me, in my head, it was a breakthrough for suburban free energy. funnily enough, the solar thing took off some years after and i believe now it will be cheaper to have professional companies to supply and install solar panels and a Tesla battery. but i had fun back in the day thinking i was going to be rich with my design of wind and solar energy for individual houses. ironically, all my neighbors have professionally installed solar panels and free electricity, while i am still connected to the power company and paying the HIGHEST electricity prices in the world. Yes, i am in Australia, where elderly ppl die each year from the cold and the heat as they cant afford to use electricity. it is 5 times higher to buy electricity here than europe or asia. hence, i wanted to build a home made free power generator (Solar and wind)
Your idea with the truck batteries would produce DC voltage when you need AC voltage for the house.
Australia has plenty of clean coal and uranium and a ban on nuclear power. We closed down coal powered stations, could have converted the to nuclear by replacing steam generated by coal fired burners with steam generated by new gen nuclear power. The power generators could have been utilised and not destroyed.
Alas, the Green Party has had too much influence and scaremongering due to the major parties requiring their coalition to remain in power and remain too short sighted to realise that their appeasement hurts average working Australians for a goal that will do nothing toward Global Warming as what we produce is but a mosquito ‘s fart in a cyclone.
We had one bushfire here a few years back, started by lightning, that emitted enough carbon dioxide in 1 week as all the coal fired power stations and vehicles in Australia emitted in 5 years.
FUCK RUclips no problems there as solar batteries only produce DC as well. All you do is generate a sine wave at 50 hz and amplify to 240v through parallel current limiters and a transformer. Switch the current limiters on and off according to required power. This is done commercially through the solar panel inverters anyway
@@AJHyland63 "Clean coal" is a myth.
It doesn't exist.
Anytime you burn anything made of carbon, you are taking that "stored" carbon and putting it into the atmosphere.
At least you understand that this action contributes to global warming.
Just because a brush fire (unverified amount by the way) contributes to global warming dosen't mean coal fired power plants are a good thing.
As far as nuclear power plants go, we've all seen what a fucking disaster those things can turn into.
And no insurance company in the world will insure them.
Think about that.
Wrong. We capture the carbon and bury it in a landfill, or sell it to concrete companies. The air out of our stacks is very clean.
Hey man I really appreciate people like you and love the content, even if it wasn’t as efficient as we hoped it was still a learning experience especially for me so I appreciate the potential life saving knowledge.
Greetings from Canada. Thanks for the very clear and concise narration and your good work.
A dc motor with permanent magnets is cheap, and requires none of the major engineering... not as much fun, perhaps, but if your goal is a working 12 volt system, that is the easiest way... it can be regulated by a automobile 12 volt regulator for cars that use a generator, rather than an alternator... Bosh for the old VWs is my personal preference... they can be used with either wind or water to generate electricity all day and night...
That being said, I think the effort was a great learning experience... that is how new technology comes about. . Excellent video sir
What about using a car alternator with a pulley system? With a big enough fan blade setup, it might make up for the pulley system?
What about a variable bearing on the alternater shaft to do away with the pulley system?
sir;
Please don’t kick yourself. In my case this is exactly what I want to do. Your instructions and explanation was fantastic. I wish my professor at the university did as good of a job as you.
nice. very interesting.
Would be interested to see how you could use a quad copter motor (or lots of them) to create power
Glad someone is doing this. I think you can do similar easier with a car starter
You can use an alternator to produce energy to run your home
Alternator also
Using an alternator works best if you include an inverter.
But you need to make some modifications to the car alternator, not very complicated but still not easy for everyone.
@@saranjimable One challenge with the alternator is that it must spin relatively quickly, so you would need some drive system (belt and pulleys, etc..) to increase the shaft speed relative the wind turbine part, which can eat some of the energy. By starting with a motor that has many poles (the hoverboard motor looked interesting) you can produce more power at lower RPM, potentially eliminating any drive line parts and therefore the parasitic losses that goes with them, potentially generating more electrical power for the same amount of wind.
It has always bewildered me why, when someone takes the trouble to share their experience and knowledge in an open way, expressing what they are learning, inviting comment and suggestions so they and others can learn, is given dislikes and negative and demeaning comments. Why is that. Negative suggestions that are disguised as personal attacks on people who are simply trying to establish a relationship with like minded people do not deserve this and it accomplish nothing but to close people off. I was an engineering manager for many years. In my world, there were no such thing as bad ideas because whatever was put forward became a stepping stone to something better. These negative type people very seldom contributed anything of worth to projects. On the other hand, cooperation, contribution, respect, flexibility and the like always lead to better outcomes and a sense of accomplishment for Everyone.
Thank you for sharing! Excellent!
Turbines can spin too fast in high winds and unloaded. It is potentially dangerous to have a load shut off in high wind just because the voltage is high.
Yeah, it would have been nice to see the feasibility of using those inner coils used as part of a braking system to stop the turbine from flying apart... maybe another video, or explanation on why that isn't a good idea?
@@pfeerick Not a bad idea. Connect a voltage dividing network of resistors to the output of the rectifyed and smoothed DC before the dc to dc converter. One 3k and one 21k with the 21k connected to + and the 3k connected to - and the middle is fed to a comparator.
The comparator is powered by 5v from the dc to dc converter. A 3v reference voltage is made with a 100k resistor and zener diode.
Then if the voltage rises to 24v, the 4k resistor drops 21v and the 1k drops 3v sending that 3v to the comparator to compare against the reference voltage. If the voltage from the voltage dividing network goes higher than the comparator, the comparator turns on switching a relay that dumps that power into a nichrome wire dissipating the power as heat. All that's needed is a few turns of thick wire on the stator. For that coil.
So now if the smoothed and recitified DC goes over 24v, the load dump coil feeds power to the load dump. The turbine will not spin any faster than when it puts out about 25-26V
The time I spent in Iowa, gave me an opportunity to sit in a dinner when a group of wind turbine company techs sat down at the next table. Conversation turned to the inner working of a commercial wind turbine. (Talking shop) They explained the largest expense inside the box is the transmission system. While some use electric braking to stabilize rotor speed, but variable pitch blades, hydraulically controlled shifting to the generator. So as wind speed increased, the calculated load increased the gear selection to add 3 sets of windings on the generator. Each produced a load to the rotor, but also increased output wattage with wind speed. Servicing the hydraulics, bearing blocks, electronics including sensors were most of the maintenance they had to perform. Then the rotor housing turns 360 degrees on a captured roller bearing system and it alone required constant maintenance. They estimate that 14 of 100 wind turbines are down at any given time due to service, waiting on parts (Most from Germany) and other issues. They have wind farms all over Iowa and now Starting in NE Nebraska in 2021 after study. Wind still produces only less than 0.2% of all the power produced in the US as of 2018. So much work to get so little with too much effort.
Variable pitch controls.
@Robert Theref Fixed.
Could you arrange the magnets in a Halbach array to double the magnetic flux? How does mounting it as a horizontal wind turbine affect the bearings given that ceiling fans are vertical axis?
If the induction motor was already on an AC supply, the speed would be fixed but any wind power would still be added to the AC grid. However should there not be enough wind, the induction motor would pull power from the grid. Unfortunately inverters don't work very well to provide the initial power source, you pretty much need actual alternators controlled by a regulated mechanical prime mover to regulate the voltage and frequency and of course an actual load. This is actually how power plants work on the grid so induction motors without magnets can be used to generate power just not without an already operating grid.
For everyone who brought up the problems of a horizontal-axis wind turbine...Google or search on RUclips to find vertical-axis wind turbines! Both designs exist.
@@LiveHappy76 Far less efficient, and the most common designs will not start rotating on their own from a dead stop. For the dynamo you're much better using one of the many self-built designs than with putting almost the same amount of effort into converting an existing device into a lesser machine.
Great narration, doesn't matter about the wind turbine, you have the basics there.
I had been contemplating this project for a while. Thanks for saving me the trouble of seeing if it works. Looks like it was a fun attempt nonetheless! Good job Giesbert.
The test prototype is the biggest learning area .
You inspire me to keep working on free energy Thanks
Thanks Randy. And what are you working on if I may ask?
Enjoyed video. If you want to learn more watch Gerard Morins videos. These work great. The best motors in my experience are the Scotter motors and the Wheel chair Motors the Torque is amazing in the wheelchair motor.Also the washing machine motors are what Mr Morin uses.Gez in the UK
You sound a lot more educated in electronics than being your first time with it.... (11:15)
This is amazing... was searching for how to open the damn motor assembly and reached this page.. this project is awesome!
Halbach array will give you almost 2x as much magnetic force in the direction of the strator. Also to regulate the over voltage store it or use it but don't let it heat the coils or it won't last long.
I found your alteration interesting. It reminds me of what many of our Bushmen do here in Alaska. Here we get a GE or Chevy alternator. It is fasted to a stand. Sometimes a home built tower. Sometimes a post. Like a flag poll. Only it is flanged so you can bolt onto the top a windmill. On the shaft of your wind blades is a corresponding pully so you can connect the rotation of the windmill to a GE Alternator by an appropriate automotive fan belt. This transfers wind into mechanical energy via the belt & pullies. In turn the mechanical energy is converted into electrical energy by the alternator. In a GE Alternator there is an internal bank of diodes. These diodes convert the 130’ish volts of a typical low end alternator or about 160’ish to 190’ish ac volts of a high output alternator into useable 12 volt via the diode bank. The only maintenance is changing the brushes inside the alternator ever so often. Also, if one of the diodes open ( think like turning off the light switch ) then you will have to replace the diode bank, but this is unusual. This is an easy setup after your tower or post is set. It is also low typically low maintenance. Now you can use a Ford Alternator or even an old cars generator to do the same thing; however, you will need some additional components to regulate the out-put of voltage. In comparison of these two options. The GE Alternator is easer to hook up to a battery bank for simple lighting. With the Ford Alternator you can get a different independent regulator rather than the automotive ones. So long as it is compatible. This will require a better set-up, but the extra effort yields more power output. Build it strong to service a wind storm and both become virtually maintenance free. Cheers everyone. I did like this video though, because I have often wondered about what this man did. Now I know. Thank you for this demonstration.
Good suggestions
Thank you Giesbert, this is the best video I've ever watched in my entire life
How about going to a garage sale hopefully you'll come across a treadmill with a generator in it, that's already equipped with digital gauge.
Treadmills have variable-speed dc motors, not generators.
I imagine that's a good basis for a generator, but I dunno for sure.
I'm looking for an article on adapting a treadmill motor to my bandsaw and my drill press...
@@markmarkw1919 Motors don't make good generators. And treadmill motors don't have the torque for cutting wood and metal.
voltage is easy to produce but it is the amperage you need to run devices. The thicker wire would work.
The wire size was chosen to run at 120volts and less than 0.5 amp, with some resistive loss in the wire. So if you ever want to get 60 watts out, the voktage would be high (120v) and the wire would be lossy... So, yes, that wire is too thin!
@@jimswenson9991 output DC or AC?
Oh, the coil makes AC. It has no "commutator" on the spinning shaft, or electronic parts "rectifier" to change it to DC. We can add the rectifier if we want to. Specifically a "full-wave bridge", which is a square of 4 diodes.
So well Displayed and
