There was recently some news about a kid making an improved reluctance motor - no rare earth materials needed and subsequently super light because no magnets or heavy core. The downside is he's patenting it, so no details have been shared; I haven't checked to see if there's a patent disclosure (the kid is from Florida, USA, so I expect a USPTO filing) but that's what the article said.
Thanks Rob for covering this like I asked of you . I appreciate it very much considering the hate I got for even asking this of you . Keep doing great work Rob
The results are ridiculous see .. so why is the gene industry doing us like this ? U said 250 milli amp vs 13-14 milli amp . That is crazy how bad they are doing us
Hi I have been watching your videos for a while, it is not my field and so I have asked the odd question ( probably very odd 🙃) but I am surprised how many people nit-pick things you do or say, comment-question great,have fun a joke 👍 but why nit-pick, you are trying to help people. Thank you again. 👍🐝🌞
some folks just like to show they know more - and they do - often the unfortunate thing is they seem to get angry about it! That bit I don't understand
As I recall when Newman appeared on the Johnny Carson show with his device, he explained some details of the construction of his magnet rotor, this thing peaked my interest so everything went into slow motion as I listened to him speak, he described five stacks of magnet wafers which were glued into five cylinders which were attached in the center creating his rotor, however the one thing that stood out when he described his device was how the five cylinders of magnets were created by gluing strong magnets north to North and South to South thereby creating an accelerated magnetic field in between each magnet glued together, I cannot seem to find that appearance on The Tonight Show with all of those details all that seems to be on the internet are Snippets.
If you are up for it Joe Newman has a rather lengthy patent application that could be a fun read. From watching some of his videos and reading some of the patent his actual motor invention is somewhat more complicated than this demo device.... well... not the thing shown here... the device up here in the video is claimed to be a core-less motor but the magnets quite fanatically want to point upwards?? The bearing also seems quite horrific if we can even call it that. But ok, it is suppose to be a stack of magnets on the axle and a coil (without ferromagnetic parts!) and some say the commutator is suppose to SPARK. (It should still kinda work with a reed tho) The more advanced application has the stack of magnets packed in ferromagnetic material. It wouldn't work as a conventional generator as the field no longer extends beyond the core. The coil pulses a magnetic field into the core flipping its polarity. You get the sum of the electromagnet and the permanent magnets extending beyond the coil. You get a much greater spike back than you put in which is suppose to trigger the sparks. Putting that back into a battery is not a very efficient process (not sufficiently) and another down side (or perhaps an upside?) is that pulsed dc rejuvenates old batteries. In the original CNN demo the giant motor runs (indefinitely) on a few tiny non rechargeable batteries that are empty, when the TV team wants to go home they measure the voltage on the batteries and they held more charge than at the beginning. People want to cry impossible and argue everyone would be doing it but building a giant device for uhh a few thousand? That can pull its own weight and put milivolts into a battery over several hours isn't actually useful. At best it can make people think.
I used to watch a lot of his videos. There's one in particular that really caught my eye. When he was demonstrating one of his coils which happened to be attached to a balloon sitting on the ground, the thing lifted in the air and oriented with the Earths' magnetic field. From the looks on his face, he didn't anticipate that happening and quickly brushed it off. He did mention that the coil was energized with the main power line, so I was scared to try it.
There is a poor quality clip of the interview on the Johnny Carson Show, about 15 minutes long, on the Physics 101 RUclips channel. Not sure if it's the full interview as I never saw the original.
Gluing North to North would not create a stronger magnetic force, You would have two Norths fighting against each other, squashing the field, there may be a small bulge radiating from the point of contact though not much. A sort of teardrop but the thin end round not pointed. If they go North to South you get a small increase in field strength, the more you stack the bigger it gets, I believe proportional to the amount of magnets used.
@@davidsoulsby1102 Actually, the idea has some merit. When you force North and North together, the magnetic field in that area is super compressed and it will appear as if it is stronger. You can try this with a sheet metal. Attach both north poles on the opposite sides of the sheet metal. No need for glue. You will find that the edges of the metal is extremely strong.
Awesome example and comparison! I do wonder how much copper (by weight) is in the small store bought genny. By looking at it I would assume much less than the Newman genny. I think showing it as an example compared to a store-bought generator of similar mass and size would still drive home your point of simplicity and cost of production. It might even be more convincing. Thank you again for another awesome video. You always do great work
Probably made in China and or, made with aluminum wiring. I have found many (75%) transformers that failed were made with aluminum wiring and no coper.. China?
It would be important to measure the power lost in the battery of the drill. It's possible it was using more power. I suspect the drill battery will last longer spinning one compared to the other. Just look at the sum of the heat generated on every component to find the winner
I heard that there are certain generators that can produce a D.C electrical current directly without generating an A.C, which will be amazing to exceed the complications and losses of electronics.
That is astounding Rob! From a DIY generator it blows my mind that it performs so well. It would be interesting to see the comparison to what the drill itself is capable of outputting. You did a video a while back where you made generators out of motors of prefab things like the drill, just curious to see how this little generator stacks up to those. Thanks Rob!
I would love to see these in a practical application. I know that's not the thrust of this channel, so it's more of an open challenge to anyone else with the wherewithal to make it happen. I'm not electrically inclined, which is why I don't do it myself. Somebody please make a practical application of this, or several, and post a video for us to see.
Fascinating! Thinking of old style rural wind turbines. A 90 degree power diverter on the output shaft directs the torque down along a light weight tubular drive shaft to the base. The head is supported by mag-lev so friction is minimal. At the base, an automotive flex plate from an wrecking yard automatic transmission is mounted to the output shaft. Geared into the flex plate at a gear ratio of approximately 1:15 is a series of Newman alternators mounted to a plate and wired in series - parallel, raising the output voltage while keeping the current low; say 1 amp. The 6 volt bulb got plenty bright running the alternator at 2100 rpm. I'm presuming about 8 volts. Two alternators in four parallel strings should yield 16 volts and 1 amp at a turbine speed of 140 rpm. Not bad for scrap parts and a few magnets!
Great demo. For a fair comparison, the strength of the magnets used and the number of coils or copper mass should matter and may explain the difference. Still, your generator was build from scraps, so it's worth experimenting with this.
FYI. I do know that forcing cylinder magnets in line and with opposing fields is used in linear thrust actuators. Makes for a very strong magnetic field and very different lines of flux. Using Cylinder magnets over a threaded rod and nuts allows you to force them together. Something worth experimenting with generation for sure!
i love how you respond to the ones how think them self smart if they only knew how they make them self truly look but that pride has them blinded just like the first sin
Great content as always! I suspect the difference here is slightly misleading. You can hear the drill spinning at full rpm in both cases, being limited by the drill itself. Differnt design of these makes it really hard to compare efficincies. As an example turning a car alternator and a small motor/generator at same rpm gives hugely different output. I understand that the point is to have something easily made perform well. I'm just trying to point out some of the reasons for the output difference. All that said, very interestin topic and I appreciate your videos very much, they are a great source of inspiration.
there are lots of reasons mate probably the most significant is just the magnet field strength - I used N35 chances are the store bought one used ceramic - but the whole point is price and home made versus shop bought - £30 versus £3 - and I put the same input in - roughly
Put cockroft walton multipliesrs off each coil; one set ground to positive, the other in reverse; ground to negative.Spark gap the positive and negative. Then capacitors off those legs to a transformer. Do whatever you want off the transformer.
Commented this several times and not giving up as it’s VERY IMPORTANT. Please show how to harness this power to change Ecoflow battery or what it would take to do so. Thanks!!!!
"Prime Movers" :) such as a set of peddles. The reason I've been watching these inspiration tutorial videos is because I own an electric scooter that can go 30 miles on a charge and I'm using the scooter on snowy and icy roads during the deepest darkest part of a Canadian winter so my idea was :) if I could "top up" the battery as I ride, even if I don't "break even" (on the charging and draining) then at the very least I can reduce the amount of drain thus prolonging my overall available distance. And after watching enough of these I feel I finally have a reasonably legitimate prototype for my setup.
Many years ago I picked up a box of scrap Marklin Gauge 1 train locos with AC motors. I followed my simple logic to get one to run on DC. By picking out the connections to the various windings and adding a couple of diodes. So the coils would only spin the motor in one direction on DC. I reasoned that an AC motor on DC would have different coils pushing in different directions at the same time. It worked, and the loco went back and forth fine using the DC controller. However, I seem to remember that if you turned the actual loco around on the track, then the loco direction reversed. Wondering if you could convert a small AC motor into a DC generator in a similar way using diodes. 🤔
Nice one Rob! - Looks like a perfect project for your "floating" magnetic bearing setup? - Looking forward to the next stage. How many people will be off down to the tip to grab some old dead microwaves this week!! Ha
Talking of Newmans, i'd love to see you do a breakdown of Joseph Newman and his ideas :) Covered in the documentary ' Newman ' (trailer on YT), by Film Rise studio. i think, his idea went as follows: That the magnetic field of a permanent magnet is itself an energy source. So he tried inventing a device that inputs a small electro-magnetic field to periodically tap into the larger permanent-magnetic field. To gain additional rotational momentum ;) Yes, i know where this takes us :). but i really enjoy when you breakdown these types of ideas.
The generator's lack of cogging and low startup torque are very attractive features for wind power generation, too. Vertical/helical turbines don't get up to the crazy high RPM that the classic sky-monsters do, but they'll spin in a breeze that your own face can scarcely feel. Generators suitable for such low RPM are few and far between.
Nice, I will have to try that. I found if I put metal behind a magnet it increases its field strength considerably maybe a small block of Steel to create the rotor place the magnets on the steel this would put the magnets closer to the coil and possibly increase your output but again I could be talking out of my a** :)
A few negative comments today I'm afraid. Thought I would check what they have come up with on their RUclips page but nothing there!! Keep up the good interesting work Rob. Most of us think what you put on every day is excellent.
I imagine you'd get even higher induced voltages with an iron keeper and magnets that are proximally closer to the coils' surface. You might actually not need the iron keeper since a large volume of copper is being cut across by the rotating magnetic field. But it's clear that for such an eccentric rotor shape like this, it needs to operate as best as possible at low speed where loss due to air drag and vibration are negligible.
Awesome as usual Robert. One question though, the magnets within the coils appear to be attracted to the upright position in your demo at 0:33, therefore is there a 'metal cross plate' between the coils where the terminals are located which is causing this? Many thanks, John (UK)
I bought Joseph Newman's book in the mid 80-s and still have it. He has interesting theories along with the design of the motor. do you have a copy Rob? have you seen his theory on the "gyron"?
That is impressive Rob! It begs the question about the secondary coils and if they may improve it even more with 10 times the windings as the other day you mentioned the length of wire was apart of the equation and efficiency!
The farther the magnet gets from the wire ,the less you will get, so there are limitations. The more wire you use , then the more resistance there is to current flow. There are trade-offs with everything. I would be interested to see the difference if the ferrous terminals were removed. I'm going to attempt one. I should say that stacking magnets that way makes a powerful magnetic field, but a single, solid magnet of the same size would be about 40 percent stronger and even generate more. I am very surprised at how well this works. Thanks Rob
@@justtinkering6713 yeah i was thinking from the perpective of far higher voltage actually travelling with lower resistance as i believe it is the case but maybe at 10 times the voltage it still isn't high enough to be something worth doing . I don't know but it might !
@@Buzzhumma All you need is enough to charge a battery. I dont know any application where you would use the output directly. Charge the battery then send that to an inverter for AC. Or you could ditch the copper coils and put a flat sheet of copper with some sort of heat exchanger to make hot water or hot air.
Great result! Could not help thinking, if you turned it on its side, with the axis running through the short ends, using a magnet with the poles through the side, you would get 3 to 4 times the power.
At the same drive rpm drill speed the Newman generator magnetic field is rotating at a much greater effective end radius, so likely travelling at a higher velocity past the wire.. plus perhaps there is more length of wire in those old transformer cores? Without knowing the winding setup inside the other gene , kind of hard to make a full comparison … another great video Robert. 👍
oh there will be quite a few reasons - like the Newman had much stronger magnets - it's likely the store bought was using ceramic magnets - but all we are showing is you can make something cheaper with. more out for the same in - that's about it really
But would the reciprocal be valid ? Can we see some overunity ? Have the commercial motor powered up, spin the Newman generator. Even if it's at 50% efficiency. Then how about adding a second magnet on the same shaft and brushes. So you get also a homopolar generator at the same time.
Better than a shop bought generator at low RPM for sure. At the 12V motors rated RPM, however, will be a different story, but its a good post-apoc build when there aren't convenient shops around!
@@Infinion it wouldn't be a different story - I am not sure why you think it would - all generators are governed by Lorentz's law where emf=BLV sine theta - at the rated rpm of a store bought generator then yes it would output more but so would the Newman generator by the same factor
@@ThinkingandTinkering I'm mostly a fan of motor characteristic curves because its less convention through theory and more practical empiricism to make conclusions with. When voltage is proportional to speed (the mentioned BLV) and current is proportional to torque (IAB), yeah the newman generator is going to scale up ... for a little bit. It might even scale by a large degree since you gave it a huge loop area with those MOT windings. But assuming the magnets don't fall apart from the centripedal forces and counter-torque, there will be some yet determined speed where "MOT Newman's" power output will plateau and efficiency drops off from electrical and mechanical losses. If the 12V motor experiences that before MOT Newman, then oh yeah your claim will most certainly hold true.
So here's a dumb question that I thought of while watching one of your other recent vids, but it applies here as well- if you set up 2 coils like that, one with thin wire (for volts), and one with thick wire (for amps), can you feed both of those to the same place to get both a decent voltage and amperage, or is that just a ridiculous notion?
Good day sir. That generator seems to be very effective. Did you measure the volts output? I would like to calculate the possible watts this type of generator makes. If it is 220V coil and you have two of them in series, is it 440V 0,25A? So the generator output is somewhere between 0-110watts. Btw. does it feel like it creates lenz braking effect while you hand spin it when it is connected to load?
Robert, according to induction, you can stack a coil on the generating coil. How high/much coils could you tie to the generator coil until you do not have a voltage coming out of it via induction?
so i want to say ive done this same thing in the past except i didnt test it against a store bought one in fact i was thinking this whole time 20 years or so that the store bought ones would be as good or better to be totally honest i just assumed they were better because its built specifically for that but anyway im assuming again but i think the coil is the reason its better because the coil has the ammount of turns it has . but i would love to see you go though testing to determine what exactly it is that would produce the best possible build for making things liek this from scrap maybe even if we took the coils down and re wound them in a closer proximity or had stronger magnets things like this
It would be interesting if you could get your hands on a Tesla car energy recovery generator to see what advancements have been made by the car company. From all my research into Nichola Tesla's work with Edison, I have been lead to believe generators have been handy capped. Just wondering.
Robert, this is ridiculous, you got one quarter of an amp from your throw together microwave unit and the commercial one was in the milliamps. WHAT is going on here fella ???? I do believe you need to go feather on the Newman unit Sir. Good luck too.
continue with the scrap/trash theme and encase it in a plastic bottle for protection and make a scrap propeller..or connect to a salvaged bicycle.. maybe even a hamster wheel!
Hi Rob! Thank you for this video! I have actually made the Newman motor generator, just to see what would happen. I am curious though, is it possible to wire 4 coils in parallel? I have a thick coil and thin coil as of now, but I want to add 2 more thick coils. I was thinking of adding another magnet rotor down the shaft and either, have the 2 additional coils wired together and send the output from each set of coils to a common post...or try to wire them together and only have one output. Any advice on how you might do it?
I'm not disagreeing completely, but you cannot say it is definitively better than the shop bought generator, just in this test it appears functions better. The Newman motor should also work better if the ends of magnets came closer to the coils. I suspect the commercial generator is designed to operate at a different RPM. It would certainly never be possible to saturate the iron in such a motor. To properly analyse, you need to perform a similar test, but at a range of RPMs and measure the torque and thereby the input energy or power. Also a range of output loads and measure voltage and current to show the power output. I'm pretty certain that the energy is all produced from the ends of the bar as they pass the coil. The flux lines parallel with the bar magnet (stack) do not produce energy, as they are not cutting through the wire perpendicularly, as on the ends of the bar. Therefore I wonder whether in place of the single bar magnet made from a stack, a rotor with the magnets arranged N-S-N-S etc. around the circumference, (ensuring N and S are always on opposite sides) would be better? The magnetic flux will be lower but you will be passing flux lines through the horizontal wires in the coil more often. The AC frequency will be multiplied by the number of N-S pairs around the circumference. I'm looking for simple but relatively efficient and in particular low RPM generators to make a 'hybrid bike'. I.e. remove all the complexity of chain etc. on an e-bike (trike in my case). Good force feedback would be desirable, with user selectability. I.e. the user will ride it like a normal bike, without an accelerator, so that the energy applied to the wheels would be proportional to the energy supplied by the user and the user would be able to vary the proportion of assist energy going to the wheels.
indeed mate lol lol - but as the load was the same - you could see the difference in performance just by looking - the lamp was very much brighter and being a filament lamp it was a resistive load - so - good for charging batteries
@@ThinkingandTinkeringcoreless generators should not have any iron losses, with lots of turns on the coil they should generate high voltage at low rpm only negative side I can think of is high resistance of coils but at low amperes with high voltage good power output can be achieved and coils should not heat up.
Hi Rob, I was revisiting your push pull inverter and had some thoughts for ya. What if mechanical switching was used in place mosfets? A Wind turbine using only coils, caps and diodes could be very useful. Food for thot. 👍keep up the great work
lol - the load was the same - you could see the difference in performance just by looking - the lamp was very much brighter and being a filament lamp it was a resistive load
@@ThinkingandTinkering yes that's what I was referring to, I noticed the dimmer lamp to. I'm just saying it could be either way. If the one motor produced at a certain rpm e.g. 6V and 2A. Your motor would produce 12Watts, but if the lamp only draws 1A because of its resistance it's only 6Watts used. If the other motor produced at the same rpm 5V and possibly up to 10Amps that would be 50W but because of the lower voltage and the resistance of the bulb it would draw less than before. Lower than 1 amp resulting in a power consumption of less than 5W thus the dimmer lightbulb. As I remember to characterize the stats of a device one needs to measure the voltage without a load. And the current/amps with a low resistance/short For example one particulare generator could be better for generating high voltages the other one lower voltages with higher current, just as there are power tools which run on 12V batteries and other need 48V. Thank you for all your content
Are we talking the same Newman motor, Joseph Newman, big powerful motor, uses very little power? Using this as a generator works great, as soon as I saw the output I immediately thought about putting on the same shaft after this coil, another bunch of magnets and another coil. And as many as we can in a row untill it starts to bog down with given power, whatever that may be, (turbine etc) or drill in this case and can connect the in series or parallel to get whatever combination of volts and amps you require.
Can you also explain how i could use the power to charge something? How do i get a stable voltage, Overvoltage protection and so on. I would charge a battery pack to then charge my cellphone and power a desk lamp.
Try searching for "diy 5V regulator" and with just couple of components found everywhere you can do it yourself. Just add USB output and done. Most of the components if not all can be found from broken CFL bulbs, if I remember correctly. Just be aware not to break the glass of the bulbs, some mercury inside.
Easiest way would be to use 5€ cigarette lighter 12V/24V to USB charger, voltage regulator bulld in. The generator outputs AC so four diodes are needed for bridge rectifier, then there are plus and minus to use for whatever needed.
er... I think it was 1/4 of an amp. But still, not bad. You would need 8 in Parallel (not series) to make 2 amps (at 6 volts). If you put them in series you simply add the voltages and keep the same current... so 8 in series would be ~48 volts and 0.25 amps.
would probably perform better if the coils were turned on their sides and the magnetic field was crossing the longer span of the coils (assuming the field strength stay the same). Are you using high voltage or low voltage coil out of the transformers?
That store bought generator probably is either a high voltage generator with a very limited current output or alternatively it is a very low voltage but very high current generator and the low current is due to the low voltage across the load.
So, I know your just throwing out basic ideas to get people interested and thinking themselves. But I still wish you would build a standardized input for theses generators so a real efficiency number could be given. You could even start a chart then and start ranking them. It would be fun. Would also be fun to challenge the audience to make a cheaper and simpler generator and send it to you for ranking.
One needs to measure both output voltage and current of generators to enable a fair comparison (Power W = V * A) and speed of rotation is critical to gain rated output. Unless I've missed something, you appear to be only measuring current and also need to be able to vary input rotation speed to generate maximum current and power. If the rating for the commercial generator of 120 Watts at 12V is correct, the max output current would be 10 Amps, provided that the input shaft speed and power is sufficient. Obviously, spinning it with a power drill is inadequate in terms of speed as it only generates .125 A, why not use a faster rotation input to find if it's true to its rating of 120 W? Your DIY machine, if it still generates double the current may well be capable of 4 times the power (I squared) or 500W which is not inconsiderable BUT you need to measure voltage and current to make a fair comparison.
knowing very little about all this Tesla stuff, I would love to see more comparisons. By the way, even the words 12 volt, 120 watts hardly register. I could have a lesson that. Volt is the difference in potential energie. Amp is the force of the current. Yes but, if the volts are higher the current will be higher? Watt is the labor. But isn’t the labor of a generator not given by the prime mover? Just how I 💭 as a electro knonothing.
I will look into it. Off topic: my biggest wish is to built a controller with arduino or raspberry pi with sensors, fan and pump for heating system, with a rocket stove outside. Just because it’s cool and alternative.
Any idea if it would be feasible to use a 3rd coil for commutation on the Newman motor? Just a single coil that follows one of the main coils and triggers the timing so both main coils can be used for power?
Getting off subject. what do you think of compressed earth block or rammed earth as a substitute for concrete block? Wow you got a quarter of an amp. Earth block or rammed earth has better thermal mass but can it be as strong?
@@ThinkingandTinkering Thanks for the fast reply. Do you know the best formulation? I have seen 10% cement and some percentage of lime. They say that the pyramids were built out geopolymer. My projects never get that far or that big.
i wonder if you sealed it ina vacuum (the whole apperatus ) and see if it relieves the friction ...just a thought as we appear to not play with the vacuum ,but tesla did in the car coil
newmans motor had second coil open circuit around the first only collecting the collapsing magnetic field and his commutator collapsed the fields many times every revolution . better efficiency. it all adds up. great generator though!

Actually, the idea has some merit. When you force North and North together, the magnetic field in that area is super compressed and it will appear as if it is stronger.
You can try this with a sheet metal. Attach both north poles on the opposite sides of the sheet metal. No need for glue. You will find that the edges of the metal is extremely strong.
Awesome example and comparison! I do wonder how much copper (by weight) is in the small store bought genny. By looking at it I would assume much less than the Newman genny.

I heard that there are certain generators that can produce a D.C electrical current directly without generating an A.C, which will be amazing to exceed the complications and losses of electronics.
That is astounding Rob! From a DIY generator it blows my mind that it performs so well. It would be interesting to see the comparison to what the drill itself is capable of outputting. You did a video a while back where you made generators out of motors of prefab things like the drill, just curious to see how this little generator stacks up to those. Thanks Rob!
I might try it mate
You are a unique excellent master ...
Wish you the best
I would love to see these in a practical application. I know that's not the thrust of this channel, so it's more of an open challenge to anyone else with the wherewithal to make it happen. I'm not electrically inclined, which is why I don't do it myself. Somebody please make a practical application of this, or several, and post a video for us to see.
Great suggestion!
lets use a small dc motor to spin the assembly with a rechargeable battery and use the assembly current output to recharge the drive battery!
this definitely changes the saying garbage in garbage out.
great video Robert
cheers mate
Fascinating! Thinking of old style rural wind turbines.
A 90 degree power diverter on the output shaft directs the torque down along a light weight tubular drive shaft to the base.
The head is supported by mag-lev so friction is minimal.
At the base, an automotive flex plate from an wrecking yard automatic transmission is mounted to the output shaft.
Geared into the flex plate at a gear ratio of approximately 1:15 is a series of Newman alternators mounted to a plate and wired in series - parallel, raising the output voltage while keeping the current low; say 1 amp. The 6 volt bulb got plenty bright running the alternator at 2100 rpm. I'm presuming about 8 volts.
Two alternators in four parallel strings should yield 16 volts and 1 amp at a turbine speed of 140 rpm.
Not bad for scrap parts and a few magnets!
for sure mate - keep them ideas coming - cheers
Great demo. For a fair comparison, the strength of the magnets used and the number of coils or copper mass should matter and may explain the difference.
Still, your generator was build from scraps, so it's worth experimenting with this.
FYI. I do know that forcing cylinder magnets in line and with opposing fields is used in linear thrust actuators. Makes for a very strong magnetic field and very different lines of flux. Using Cylinder magnets over a threaded rod and nuts allows you to force them together. Something worth experimenting with generation for sure!
i love how you respond to the ones how think them self smart if they only knew how they make them self truly look but that pride has them blinded just like the first sin
ain't that the truth lol
Your on beast mode for all the brilliant content you are throwing at us !!! Thank you very mucj
Great content as always!
I suspect the difference here is slightly misleading.
You can hear the drill spinning at full rpm in both cases, being limited by the drill itself. Differnt design of these makes it really hard to compare efficincies. As an example turning a car alternator and a small motor/generator at same rpm gives hugely different output. I understand that the point is to have something easily made perform well. I'm just trying to point out some of the reasons for the output difference.
All that said, very interestin topic and I appreciate your videos very much, they are a great source of inspiration.
there are lots of reasons mate probably the most significant is just the magnet field strength - I used N35 chances are the store bought one used ceramic - but the whole point is price and home made versus shop bought - £30 versus £3 - and I put the same input in - roughly
Put cockroft walton multipliesrs off each coil; one set ground to positive, the other in reverse; ground to negative.Spark gap the positive and negative. Then capacitors off those legs to a transformer. Do whatever you want off the transformer.
Newman motor became very popular with the free energy crowd back in 2000 or so.
yes it did
Commented this several times and not giving up as it’s VERY IMPORTANT. Please show how to harness this power to change Ecoflow battery or what it would take to do so. Thanks!!!!
Isn't that someone else's commercial venture? Why not go to their RUclips channel and ask them LOL
there is lots of info on how to do that - give it a go
"Prime Movers" :) such as a set of peddles. The reason I've been watching these inspiration tutorial videos is because I own an electric scooter that can go 30 miles on a charge and I'm using the scooter on snowy and icy roads during the deepest darkest part of a Canadian winter so my idea was :) if I could "top up" the battery as I ride, even if I don't "break even" (on the charging and draining) then at the very least I can reduce the amount of drain thus prolonging my overall available distance. And after watching enough of these I feel I finally have a reasonably legitimate prototype for my setup.
nice - let me know how you get on
Many years ago I picked up a box of scrap Marklin Gauge 1 train locos with AC motors. I followed my simple logic to get one to run on DC. By picking out the connections to the various windings and adding a couple of diodes. So the coils would only spin the motor in one direction on DC. I reasoned that an AC motor on DC would have different coils pushing in different directions at the same time. It worked, and the loco went back and forth fine using the DC controller. However, I seem to remember that if you turned the actual loco around on the track, then the loco direction reversed. Wondering if you could convert a small AC motor into a DC generator in a similar way using diodes. 🤔
very interesting - I'll bet you could
From one Newman to another, way to go. Thanks for the fun educational vids. Inspirational
cheers mate
Thanks mate 👍 Hope you look into building a bigger version. Great job
you could always try that mate
Nice one Rob! - Looks like a perfect project for your "floating" magnetic bearing setup? - Looking forward to the next stage. How many people will be off down to the tip to grab some old dead microwaves this week!! Ha
Talking of Newmans, i'd love to see you do a breakdown of Joseph Newman and his ideas :)
Covered in the documentary ' Newman ' (trailer on YT), by Film Rise studio.
i think, his idea went as follows:
That the magnetic field of a permanent magnet is itself an energy source. So he tried inventing a device that inputs a small electro-magnetic field to periodically tap into the larger permanent-magnetic field. To gain additional rotational momentum ;)
Yes, i know where this takes us :). but i really enjoy when you breakdown these types of ideas.
Very cool!
oh wow - cheers mate - that is very much appreciated
Wow. Looks like you've inadvertently blown the cover off an entire industry. But that's how paradigms shift and true science advances. All the best.
cheers mate
The generator's lack of cogging and low startup torque are very attractive features for wind power generation, too. Vertical/helical turbines don't get up to the crazy high RPM that the classic sky-monsters do, but they'll spin in a breeze that your own face can scarcely feel. Generators suitable for such low RPM are few and far between.
Nice, I will have to try that. I found if I put metal behind a magnet it increases its field strength considerably maybe a small block of Steel to create the rotor place the magnets on the steel this would put the magnets closer to the coil and possibly increase your output but again I could be talking out of my a** :)
do it mate - I can't think of an easier build project
A few negative comments today I'm afraid. Thought I would check what they have come up with on their RUclips page but nothing there!! Keep up the good interesting work Rob. Most of us think what you put on every day is excellent.
there never is mate - some folks are full of it lol
That's pretty impressive 👏👏👏
Thank you! Cheers!
I imagine you'd get even higher induced voltages with an iron keeper and magnets that are proximally closer to the coils' surface. You might actually not need the iron keeper since a large volume of copper is being cut across by the rotating magnetic field. But it's clear that for such an eccentric rotor shape like this, it needs to operate as best as possible at low speed where loss due to air drag and vibration are negligible.
maybe but you would also get cogging - which would mean it wouldn't operate well at low speeds
Great video ! good luck with your work !
I liked the idea of the trained elephant 😂😂😂
Awesome as usual Robert. One question though, the magnets within the coils appear to be attracted to the upright position in your demo at 0:33, therefore is there a 'metal cross plate' between the coils where the terminals are located which is causing this?
Many thanks, John (UK)
Rob your laugh is therapy
cheers mate
I bought Joseph Newman's book in the mid 80-s and still have it. He has interesting theories along with the design of the motor. do you have a copy Rob? have you seen his theory on the "gyron"?
That is impressive Rob!
It begs the question about the secondary coils and if they may improve it even more with 10 times the windings as the other day you mentioned the length of wire was apart of the equation and efficiency!
The farther the magnet gets from the wire ,the less you will get, so there are limitations. The more wire you use , then the more resistance there is to current flow. There are trade-offs with everything. I would be interested to see the difference if the ferrous terminals were removed. I'm going to attempt one. I should say that stacking magnets that way makes a powerful magnetic field, but a single, solid magnet of the same size would be about 40 percent stronger and even generate more. I am very surprised at how well this works. Thanks Rob
@@justtinkering6713 yeah i was thinking from the perpective of far higher voltage actually travelling with lower resistance as i believe it is the case but maybe at 10 times the voltage it still isn't high enough to be something worth doing . I don't know but it might !
@@Buzzhumma All you need is enough to charge a battery. I dont know any application where you would use the output directly. Charge the battery then send that to an inverter for AC. Or you could ditch the copper coils and put a flat sheet of copper with some sort of heat exchanger to make hot water or hot air.
Great result! Could not help thinking, if you turned it on its side, with the axis running through the short ends, using a magnet with the poles through the side, you would get 3 to 4 times the power.
maybe
At the same drive rpm drill speed the Newman generator magnetic field is rotating at a much greater effective end radius, so likely travelling at a higher velocity past the wire.. plus perhaps there is more length of wire in those old transformer cores? Without knowing the winding setup inside the other gene , kind of hard to make a full comparison … another great video Robert. 👍
oh there will be quite a few reasons - like the Newman had much stronger magnets - it's likely the store bought was using ceramic magnets - but all we are showing is you can make something cheaper with. more out for the same in - that's about it really
... love your work Robert. You are a real treasure.
But would the reciprocal be valid ? Can we see some overunity ? Have the commercial motor powered up, spin the Newman generator. Even if it's at 50% efficiency. Then how about adding a second magnet on the same shaft and brushes. So you get also a homopolar generator at the same time.
Better than a shop bought generator at low RPM for sure. At the 12V motors rated RPM, however, will be a different story, but its a good post-apoc build when there aren't convenient shops around!
no - actually it wouldn't
@@ThinkingandTinkering What?
@@Infinion it wouldn't be a different story - I am not sure why you think it would - all generators are governed by Lorentz's law where emf=BLV sine theta - at the rated rpm of a store bought generator then yes it would output more but so would the Newman generator by the same factor
@@ThinkingandTinkering I'm mostly a fan of motor characteristic curves because its less convention through theory and more practical empiricism to make conclusions with. When voltage is proportional to speed (the mentioned BLV) and current is proportional to torque (IAB), yeah the newman generator is going to scale up ... for a little bit. It might even scale by a large degree since you gave it a huge loop area with those MOT windings. But assuming the magnets don't fall apart from the centripedal forces and counter-torque, there will be some yet determined speed where "MOT Newman's" power output will plateau and efficiency drops off from electrical and mechanical losses. If the 12V motor experiences that before MOT Newman, then oh yeah your claim will most certainly hold true.
So here's a dumb question that I thought of while watching one of your other recent vids, but it applies here as well- if you set up 2 coils like that, one with thin wire (for volts), and one with thick wire (for amps), can you feed both of those to the same place to get both a decent voltage and amperage, or is that just a ridiculous notion?
it would very much depend on how you 'feed' them mate
Finally took 15 years for someone to try it
You are the Prime Mover dear sir!
lol awesome one mate - cheers
Would love to see an attempt to leverage buoyancy in a "gravity battery" using this generator
Good day sir. That generator seems to be very effective. Did you measure the volts output? I would like to calculate the possible watts this type of generator makes. If it is 220V coil and you have two of them in series, is it 440V 0,25A? So the generator output is somewhere between 0-110watts. Btw. does it feel like it creates lenz braking effect while you hand spin it when it is connected to load?
Robert, according to induction, you can stack a coil on the generating coil. How high/much coils could you tie to the generator coil until you do not have a voltage coming out of it via induction?
What about if you had magnets at 90 degrees to the present magnets would that produce more power.
so i want to say ive done this same thing in the past except i didnt test it against a store bought one in fact i was thinking this whole time 20 years or so that the store bought ones would be as good or better to be totally honest i just assumed they were better because its built specifically for that but anyway im assuming again but i think the coil is the reason its better because the coil has the ammount of turns it has . but i would love to see you go though testing to determine what exactly it is that would produce the best possible build for making things liek this from scrap maybe even if we took the coils down and re wound them in a closer proximity or had stronger magnets things like this
I wonder what a Radio controlled model aircraft starter would generate if you were to spin it?
give it a go
wrong way round are the coils, look where most wire is on the sides but the ends is where the most generation occurs.
I saw one demonstration the gave a one to ten out put.
oh right
Very enjoyable, thanks Rob.
cheers mate
It would be interesting if you could get your hands on a Tesla car energy recovery generator to see what advancements have been made by the car company. From all my research into Nichola Tesla's work with Edison, I have been lead to believe generators have been handy capped. Just wondering.
Robert, this is ridiculous, you got one quarter of an amp from your throw together microwave unit and the commercial one was in the milliamps.
WHAT is going on here fella ???? I do believe you need to go feather on the Newman unit Sir. Good luck too.
it probably the magnets in the commercial unit are ceramic - so the Bfield here was pretty strong
Mr. Smith. Will you work on building and creating a 3-D printer filament extruder so users could help develop a 3D filament recycle machine
Muito obrigado pela oportunidade de aprender com seus vídeos.
👍🇧🇷🙏🏼
I'm a big fan of SRMs over magnet motors. Was there a follow up to video 1234?
What kind of reverse power can you get with it. I mean if you put a current thought it, rpms and so forth.
Got idea. Use your Newman motor to run the mighty mite.
nice
continue with the scrap/trash theme and encase it in a plastic bottle for protection and make a scrap propeller..or connect to a salvaged bicycle.. maybe even a hamster wheel!
nice one
Impressive
Awesome, now you just need to test the peak wattage of Luke as the input, he might be able to solve the energy crisis!
lol - indeed
Hi Rob! Thank you for this video! I have actually made the Newman motor generator, just to see what would happen. I am curious though, is it possible to wire 4 coils in parallel? I have a thick coil and thin coil as of now, but I want to add 2 more thick coils. I was thinking of adding another magnet rotor down the shaft and either, have the 2 additional coils wired together and send the output from each set of coils to a common post...or try to wire them together and only have one output. Any advice on how you might do it?
What a great comparison 👏👏👏
cheers mate
I'm not disagreeing completely, but you cannot say it is definitively better than the shop bought generator, just in this test it appears functions better. The Newman motor should also work better if the ends of magnets came closer to the coils.
I suspect the commercial generator is designed to operate at a different RPM.
It would certainly never be possible to saturate the iron in such a motor.
To properly analyse, you need to perform a similar test, but at a range of RPMs and measure the torque and thereby the input energy or power. Also a range of output loads and measure voltage and current to show the power output.
I'm pretty certain that the energy is all produced from the ends of the bar as they pass the coil. The flux lines parallel with the bar magnet (stack) do not produce energy, as they are not cutting through the wire perpendicularly, as on the ends of the bar. Therefore I wonder whether in place of the single bar magnet made from a stack, a rotor with the magnets arranged N-S-N-S etc. around the circumference, (ensuring N and S are always on opposite sides) would be better? The magnetic flux will be lower but you will be passing flux lines through the horizontal wires in the coil more often. The AC frequency will be multiplied by the number of N-S pairs around the circumference.
I'm looking for simple but relatively efficient and in particular low RPM generators to make a 'hybrid bike'. I.e. remove all the complexity of chain etc. on an e-bike (trike in my case). Good force feedback would be desirable, with user selectability. I.e. the user will ride it like a normal bike, without an accelerator, so that the energy applied to the wheels would be proportional to the energy supplied by the user and the user would be able to vary the proportion of assist energy going to the wheels.
high voltage coreless generators are good for lightning up bulbs :) nice video! Kind regards!
indeed mate lol lol - but as the load was the same - you could see the difference in performance just by looking - the lamp was very much brighter and being a filament lamp it was a resistive load - so - good for charging batteries
@@ThinkingandTinkeringcoreless generators should not have any iron losses, with lots of turns on the coil they should generate high voltage at low rpm only negative side I can think of is high resistance of coils but at low amperes with high voltage good power output can be achieved and coils should not heat up.
Hi Rob, I was revisiting your push pull inverter and had some thoughts for ya. What if mechanical switching was used in place mosfets? A Wind turbine using only coils, caps and diodes could be very useful. Food for thot. 👍keep up the great work
And if anyone wants to whimper about the drill, ponder that it's a constant speed.
so awesome I love it, thank you. have a wonderful day
Thank you! You too!
I'm not sure if the comparison is correct. Because you used the drill which has a fixed rpm.
You need to measure the V and the A to calculate the W
lol - the load was the same - you could see the difference in performance just by looking - the lamp was very much brighter and being a filament lamp it was a resistive load
@@ThinkingandTinkering yes that's what I was referring to, I noticed the dimmer lamp to.
I'm just saying it could be either way.
If the one motor produced at a certain rpm e.g. 6V and 2A. Your motor would produce 12Watts, but if the lamp only draws 1A because of its resistance it's only 6Watts used.
If the other motor produced at the same rpm 5V and possibly up to 10Amps that would be 50W but because of the lower voltage and the resistance of the bulb it would draw less than before. Lower than 1 amp resulting in a power consumption of less than 5W thus the dimmer lightbulb.
As I remember to characterize the stats of a device one needs to measure the voltage without a load. And the current/amps with a low resistance/short
For example one particulare generator could be better for generating high voltages the other one lower voltages with higher current, just as there are power tools which run on 12V batteries and other need 48V.
Thank you for all your content
Are we talking the same Newman motor, Joseph Newman, big powerful motor, uses very little power? Using this as a generator works great, as soon as I saw the output I immediately thought about putting on the same shaft after this coil, another bunch of magnets and another coil. And as many as we can in a row untill it starts to bog down with given power, whatever that may be, (turbine etc) or drill in this case and can connect the in series or parallel to get whatever combination of volts and amps you require.
that's the one
Thank you!! May I ask, what is the RPM of your drill/primary driver?
Can you also explain how i could use the power to charge something? How do i get a stable voltage, Overvoltage protection and so on. I would charge a battery pack to then charge my cellphone and power a desk lamp.
Try searching for "diy 5V regulator" and with just couple of components found everywhere you can do it yourself. Just add USB output and done.
Most of the components if not all can be found from broken CFL bulbs, if I remember correctly. Just be aware not to break the glass of the bulbs, some mercury inside.
stick a voltage regulator in there - you can just buy them as single chip
Easiest way would be to use 5€ cigarette lighter 12V/24V to USB charger, voltage regulator bulld in. The generator outputs AC so four diodes are needed for bridge rectifier, then there are plus and minus to use for whatever needed.
Can you design a railway wheel bar magnetic bearing generator?
0.5 of an amp. So adding another 3 sets in series, would get 2amps WOW.
Would love to see you build on this. 👍🇫🇴
er... I think it was 1/4 of an amp. But still, not bad. You would need 8 in Parallel (not series) to make 2 amps (at 6 volts). If you put them in series you simply add the voltages and keep the same current... so 8 in series would be ~48 volts and 0.25 amps.

would probably perform better if the coils were turned on their sides and the magnetic field was crossing the longer span of the coils (assuming the field strength stay the same). Are you using high voltage or low voltage coil out of the transformers?
maybe - give it a go
I think a drill is just a handy tool for testing.
That store bought generator probably is either a high voltage generator with a very limited current output or alternatively it is a very low voltage but very high current generator and the low current is due to the low voltage across the load.
low cottage? what do small houses have to do with it mate?
@@ThinkingandTinkering Sorry I meant low voltage. Darn that auto spell check. haha
So, I know your just throwing out basic ideas to get people interested and thinking themselves. But I still wish you would build a standardized input for theses generators so a real efficiency number could be given. You could even start a chart then and start ranking them. It would be fun. Would also be fun to challenge the audience to make a cheaper and simpler generator and send it to you for ranking.
you know you could always just build that yourself right?
One needs to measure both output voltage and current of generators to enable a fair comparison (Power W = V * A) and speed of rotation is critical to gain rated output.
Unless I've missed something, you appear to be only measuring current and also need to be able to vary input rotation speed to generate maximum current and power.
If the rating for the commercial generator of 120 Watts at 12V is correct, the max output current would be 10 Amps, provided that the input shaft speed and power is sufficient.
Obviously, spinning it with a power drill is inadequate in terms of speed as it only generates .125 A, why not use a faster rotation input to find if it's true to its rating of 120 W? Your DIY machine, if it still generates double the current may well be capable of 4 times the power (I squared) or 500W which is not inconsiderable BUT you need to measure voltage and current to make a fair comparison.
What if you wrap spots of metal wire around the coil? To give it some yolk. Not sure till is the right term but im sure you know what i mean
give it a go mate
knowing very little about all this Tesla stuff, I would love to see more comparisons.
By the way, even the words
12 volt, 120 watts
hardly register. I could have a lesson that.
Volt is the difference in potential energie. Amp is the force of the current. Yes but, if the volts are higher the current will be higher?
Watt is the labor. But isn’t the labor of a generator not given by the prime mover?
Just how I 💭 as a electro knonothing.
no mate - if volts are higher current won't necessarily be higher
I will look into it. Off topic: my biggest wish is to built a controller with arduino or raspberry pi with sensors, fan and pump for heating system, with a rocket stove outside. Just because it’s cool and alternative.
Cascade a bunch of them Rob 😃
why?
Very cool. Question: if the coils are copper wire, why do I see cogging? Do you have a piece of steel in there somewhere?
Atleast the points he is clamping the wires seem to be other material than copper.
@@Teknopottu Maybe the terminals?
@@justtinkering6713 Yeah, that's the word. Non-native english speaker here who is also tired.
@@Teknopottu thanks
moving a magnet or iron past copper creates a magnetic field in the copper that is where we get the electrical power from
Any idea if it would be feasible to use a 3rd coil for commutation on the Newman motor? Just a single coil that follows one of the main coils and triggers the timing so both main coils can be used for power?
I would think that would be easy to do mate - I also thought of pulling one coil from a standard dc motor and using that as a tickler coil
Getting off subject. what do you think of compressed earth block or rammed earth as a substitute for concrete block? Wow you got a quarter of an amp. Earth block or rammed earth has better thermal mass but can it be as strong?
ervything is good in it's place mate - rammed earth is awesome for lots of jobs like home building and walls - not so good for bridges
@@ThinkingandTinkering Thanks for the fast reply. Do you know the best formulation? I have seen 10% cement and some percentage of lime. They say that the pyramids were built out geopolymer. My projects never get that far or that big.
So we know it produces at least 6 volts at 1/4 amp. So, at least 1.5 watts at roughly 300 rpm (whatever the drill is spinning at)?
pretty much - the drill is likely to be 3-400rpm
All I need now is a couple of broken microwave ovens! 🙂
you can get similar outputs from a motorcycle starter motor.. the more power hungry the motor the better a generator it becomes
i wonder if you sealed it ina vacuum (the whole apperatus ) and see if it relieves the friction ...just a thought as we appear to not play with the vacuum ,but tesla did in the car coil
I think friction is the least of your problems, the actual resistance from magnets might be way more. But then again, I am not an engineer.
vacuum is not much of an issue mate
Brilliant!
cheers mate
newmans motor had second coil open circuit around the first only collecting the collapsing magnetic field and his commutator collapsed the fields many times every revolution . better efficiency. it all adds up. great generator though!
