Hello Everyone, and thanks for your support!
Here's a video on how I turned a lawn mower and an alternator into an Emergency Power Generator ruclips.net/video/88774ED_E8k/видео.html
I have a question and please forgive me if it sounds stupid . I don't have any electrical knowledge but I was wondering could you make the generator spin faster than the motor by using a gear system commonly used on bicycle with the bigger and smaller gear ratios? I hope that makes sense. Please let me know I've been thinking about this for awhile.
Pretty much the same thing the military did with their small generators, with single, two, and four cylinder engines. How many amps does this push out?
this video is great for 1 big reason. Most people just use a transformer to convert the 12v to 120v which is fine for heaters and light bulbs but won't work for 1 big reason for electronics. FREQUENCY. car alternators have a frequency in the 1000's while the grid and electronics need 60hz (50hz in some places). this method makes it so its 120v at 60 hz (if spun at the correct speed). I'm going to be attempting this to build a generator that can synchronize with the grid (look up generator synchronization) to see if I can feed the grid using a engine and this generator along with some electronics to control the electromagnet. Keeping the engine at max throttle and controlling the field strength to control the voltage (exactly like a real power plant)
Well, for starters, increasing it's loops to 60 was totally unnecessary as Alternators produce 110 volts to start with. It's the diodes and voltage regulator that lower it to 12 volts. And the output depends on the voltage you apply to the brushes, which create the magnetic field on the armature. 12 volts applied to the brushes will produce 110 volts output in the coils inside the casing.
so if he only removes the diode and runs the altrernator he''ll have the 120 volts?
so to get the 220 he has to run 2 alternators to double the current?
@@stoner4 In answer to the first part: All the diodes do are to make sure only ONE polarity is traveling down that line. So the diodes are placed in there to change it from AC current to DC current. The voltage regulator is what lowers the voltage to 12 volts. An alternator is basically a 3 phase generator.
In response to the second: I live in the US so alternators here are designed to produce 110. In European countries the alternators might be produced differently and the actually AC output of those may be 220 volts. So I can't be certain that it would require 2 alternators to get 220, but I do know that, to my knowledge, it would require 2. There is, however, one caveat: You could also add a power booster to increase the 110 to 220.
That is false, alternators put out 12 volts AC and the diodes and regulator keep it at 12 volts and convert it to dc. As a car engine spins faster the voltage produced will go up and you can have that in a car. with only 5 turns of wire normally The voltage can only be 12v's by putting more turns you capture more of the energy and increase the voltage to 120. Also the reason this is preferred to a transformer converting 12v ac to 120ac in the last big problem. FREQUENCY. the grid and most electronics need 60hz and a car alternator is a few thousand hz which for restive loads such as heaters and light bulbs in fine but for electronics and other applications is not fine
AC does not work in series like DC does unless you add complex circuitry balancing the multiple power sources.
@@bigrenegade7121 thank you so much I'll have to get an old alternator from the junk yard and possibly connect it with a 12 volt battery powered motor or a bicycle wheel, with a motot connected to the axle, that might work.!! So I should bypass the diodes or disconnect them or maybe connect them by a separate wire to run the electric motor to run the bike wheel, anything to get the alternator putting out 120!
I wonder what this guy pays monthly for his power bill?
But, on a related note, I need to start converting and building my own electric generators and motors.
Dude, that was Next Level, well done!
If you can remake the regulator to keep a constant voltage. Turn it to high voltage DC, send the power to a H-Bridge, feed the H-Bridge with SPWM to produce a usable 50-60hz 120v ac output (like in a switching inverter, 12vdc -> something high voltage DC -> H-bridge with spwm -> usable power)
You have 3 coils connected in series, but the 3 coils are out of phase. What voltage do you get across individual coils?
Imagine a world where innovative video creators like this one actually answered our questions! I become giddy just thinking about it!
What is the slowest the motor can turn and still have 120 volts produced?
It seems fantastic to me how you have explained the new winding to reach 120v. Thank you very much friend, I congratulate you.
I really appreciate your comment, and thank you for your support!
Hi, could you give more information on how to use this to power multiple appliances? Can I attach a power strip the same way you attached the extension cord, or is there a more organized way?
I wonder how efficient is.. I mean Watts going in at 12V in to Watts coming out at 110V? How does this figure compare with just running a 12V to 110V inverter off the same battery? Thanks for your as always detailed explanations and clear images!
I'm guessing the 12v motor is just for demonstration purposes. In a real world setting you would have it hooked up to a gas powered engine or a turbine.
There is a much simpler way to do this. Use a transformer to convert the 12vac to 120vac, you don't need to rewind the alternator, just bypass the bridge rectifier to get the 12v ac output.
You could use a microwave oven transformer and replace the 2000 turn winding with 12 turns.
What frequency is the electricity that is produced?
You can make 120 vdc from a regular Delco alternator if you full field it and spin it about 7000 rpm.
That's a good possibility, but it'll require maybe at least a 10HP motor to drive it to reach that high RPM with full field applied.
@@mrmightytiger7385 I have done it with a 5 hp engine to make a generator for lights and universal brushed motors. 700 watts or so.
But it burns out the alternator! Seen it done,so that's why I wouldn't recommend it!
@@madhounddog04 you need to start with a 100 amp or so alternator. A few years ago i made one and ran a coffee pot and lights off of it without any problems. I used it to run drills and electric saws with too.
@@greasezert2228 what size wires did you use,?
120 v and how much ampers ???
Great video. Was wondering if this generator would be powerful enough to charge a homes battery bank?
Where did you purchase your wire?
If if its 120v at 60hz it would. As long as your battery bank is meant to be powered from a regular 120 wall outlet.
What are you going to do when the 12v battery dies ?
mientras la bateria tenga voltage que alimenta el rotor 12 voltios y alimeta el motor 12v funcionara sacando 120v pero la bateria no resibe carga por lo que no es funcional por mucho tiempo solo mientras la bateria tenga su carga porq el rotor no puede cargar la bateria porq su trabojo es magnetisar y generar 120v buen video ,👍
Osea que esta aplicando voltage al rotor? No entiendo esa parte
I wonder how well it will work to have 6 windings instead of 10 for 72v to directly power a dc motor for a e motorcycle or scooter.
Thanks, now my problem is solved too in that the light bulbs and power tools will work at a higher frequency. The reason the power tools work is because they rectify the voltage to DC and have a built in voltage regulator. The light bulbs just seem to be brighter at 216 Hz.
i know this is 6 months too late but here is how i would do it
take a alternator remove the voltage rectifier and diode pack
take each of the wire pairs (1 pair per phase) and record the voltage of each when spinning at the right speed to make 50hz (or 60hz depending where you are) with 8-10v at the brushes from a bench power supply to given you voltage X at the wire pairs (also record the rpm for the required frequency)
take 120v divided by your voltage X to give you the amount you need to step up the voltage by
put in a step up transformer of the correct ratio to get your 120v
repeat for the other 2 phases
do not join all the phases as shown in this video each set of 2 wires is a seperate phase and shouldn't be joined (would like to see the video setup on an osiliscope i doubt the ac is remotely clean)
now set your drive motor to the required speed for your 50hz or 60hz and add your load (tools or lights) recording the voltage when the voltage drops you increase the voltage at the brushes to compensate ad bring the voltage back up (this will increase load on the drive motor so watch the rpm and hz as too much load will also cause it to drop)
if you use all 3 phases (seperately) try and keep equal loads as when you adjust the voltage to the brushes for the lowest phase it will also increase the voltage on the other 2 phases
the limiting factors for this setup is wire diameter (alternator and transformer) which will limit current, tell tale of overcurrent is getting hot
drive motor hp - as the brush voltage is raised the magnetic forces increase creating more load to turn the alternator
brush power supply voltage and current (as electrical loads increase you'll need more and more power at the brushes to maintain 120v ac)
@@jasonpeace91 you're idea sounds good. You should make a vid and post. I would like to see it done so I can do the same haha.
Thank.
Excellent work! Thank you!
Thank you, and I'm glad you enjoyed it!
Looks good, what is the Hz of the output power
All that's not necessary....just excite the field with the stater s output...get the RPMs up...walla 120v AC...just use a battery to initial start..
What was the size of the original copper winding that you replaced with 23 AWG Wire? Also, you made 60 loops of 23 AWG but were you counting only 30 loops each on each nail or did you in fact go around each nail 60 times?
Couldn't have worked just by removing the rectifier from the alternator?
Very well done
So the question is what is recharging the battery and the second is what was the THD of your Alternator and what did the sine wave look like? And what was the Frequency at, lighting a bulb is one thing but modern electronics is something else entirely. But that was a nice way to test proof of concept. That was nice work with the rewiring the stator, I see your a man of Patients. Good video.
Connect 200watt transformer and step down to 12volt and rectified and charge the battery same time with a super capacity banks in parallel and you get a good system
Why not install a 120v motor and let it power itself?
Awesome idea. Well explained. Thank you
Thank you for your support!
And how to contact you
You couldn't connect 10 car alternators in series?
I'm not a pro, I have a natural fear of angry pixies.
Please how much to make me one ?
How many hertz at voltage output
220Hz 121vac
It can't be 220hz
@@kingzrecap1835 60hz ish. it depends on the rpm of the system. the faster it spins the higher the frequency
Why did you use smaller diameter copper wire instead of same diameter
Porque tienes que meter más espiras de bobinado, en el mismo agujero.
@@Bectris1 Thank you for your comments and support. Yes, you'd need space to accommodate more turns in the coil.
If you change the pulley make the motor pulley larger than the pulley of alternator then reconnect..but remember the key is coated copper otherwise it will be just a trap
Hasn't anyone noticed he took a 12 vdc alternator rewound the wires times 10 ie 6 to 60 then says he gets 120vac after changing the windings to series. How is it you yet ac from a dc alternator jst by removing the voltage regulator and increasing the windings then connecting them in series?
I like it you do it . I want to learn it
I like this but what could be done to remove the need for the pulley and replace with gear on gear?
Pulleys are the easiest to put together, and easily adjustable.
It's a lot easier, and cheaper to use a 5 h.p. A/C motor as a generator and no rewiring is necessary.
you need to use a synchronous motor which is very expensive and rare. most ac motors are induction motors which won't work
What frequency, or hertz would this produce?
60hz as it would spin around 3600rpm to put out 120v
Wow iv been waiting for someone to rewind a car alternator to make 120v ac awsome work I did this back then without rewinding it was able to power a light but not enough volts also I wonder what the output would to with a hydrogen generator you just have to convert it back to DC
I don't understand why people are calling us fake maybe I miss something I don't think he's trying to say this is free energy. Once the battery dies the system will turn off. If it was hooked to a wind turbine or water wheel. It should work as shown
Please tell us how you did the rotor combination befor, to work?
Did you use a diode?
There were no diodes or voltage booster circuit used.
Hm ..... Looks easy enough
If you use a smaller pulley for the alternator would it increase power output
You could be correct, but the DC motor will need to work harder.
Mr. Mighty Tiger, I respect you highly good sir. Outstanding video. If I find anything cool I will share back as you have shown me something really great. Take Care my Friend 🙂
Ok rebibinaste el alternado a 110 pero donde esta la energia libre si ahora pusiste un motor dc a mover el alternador agotando la carga de la bateria
connect to an engine
The system is powered by a battery, which turns a DC motor which then turns the modified car alternator, to produce 120V AC (at 215Hz and unknown shape) but the power output has to be 80% x 80%, so maybe 65% of the battery output (off the top of my head)? Why not use a solid state inverter with 85%-90% efficiency and no moving parts (no wear and tear and no noise)?
I'm guessing it's because this modified alternator can be connected to anything that spins. Dc motor, diesel generator, gas generator, wind turbine, water wheel, bicycle tire, etc......
the motor is just for demonstration. in the real world you would connect it to a engine or turbine.
How it is working? What type of alternator are you using with it ? Is it 12v dc or 24v dc alternator?
It's a 12 volt alternator. If you go on Amazon, it says so!
You used that bare-copper wire to make your template and I was concerned you were going to use that for your windings! 😨But then you pulled out the spool of enameled wire. 😌
Why the battery
Amazing
Ohms law rocks
Well you have your 120 Volts. How much amperage??
In ac is wattage what matters.
Hi what would happen if you removed rotor magnets and fix 2x n/s would you get same voltage but 50hz?
I'll have to think about trying it out next time.
@mrmightytiger7385 can you explain why the brushes of the alternator need to be powered?
Schematic?
hi sir u expel is 22o v farmola and dc motor hp plz
I have built one of these - my alternator has 6 leads becoming out of the stator.
It's a Ford G3 alternator.
I do not know how the wires connects.
Would you email me so I can send you photos.
Great video.
Sorry Bruce, I do not know anything about Ford G3 alternator. Google would be a better resource.
I didn’t even know alternators put out a/c power
So are you saying that the battery is charged at all times,and you are running endless power let me no.I will be waiting for response or this setup will last for 20 minutes no more.
This setup is not a free-energy device. It's how to covert an alternator output directly to 120v AC without an inverter.
Thank you
In your other video on your page, where you able to get alternator to charge battery with 1 HP motor and then from inverter connected to battery run AC power successfully and keep battery charged or not..
Excelent
How many amps did dc motor consume
Sorry I didn't take the reading.
What's the frequency of the ac?
At 120v it was about 216 Hz. Refer to the video at about 10:24
@@mrmightytiger7385 thanks
@@mrmightytiger7385 too high to run anything other than resistive loads.
@@mrmightytiger7385 it can't be 216 Hz if that what you got then ....
Have you schematics how wired
I do not have a schematic. If you refer to the video starting from 6:20 through 7:50, there should be explaining of how everything was connected including the armature winding configuration. Thanks for your support!
@@mrmightytiger7385 Thanks
Really this works ?
Try cutting some wood with that jigsaw and see how it works!!!
👍👍👍
J want To bay one
Would you be interested in building one and selling it to me?
3 phases in series just don't work, output voltage across A-C is 0v. I did this experiment as you shows and got the output 0V. So this is FAKEd.
Thanks bro I thought I was the only one that saw it if he is truly getting ac then it has to be single or 3 phase
J need one To bay completly how much, that, and J don't want feke J 'm yo Haïti.
Please translate to Arabic, thank you
there is not electric in my contry
What country pls
no feke,

Watched the over unity video, are all these videos fake then? Dont know who to trust watching any of these videos. Thanks for making it like all tge rest. Unsubscribing ☹
I put out a follow up video "Over Unity Exposed". Sorry to hear you didn't like this video. This video is real. It puts out 120v AC, but Amperage is lower than the original design.
fake-fake-fakeeeeeee
No,you are! I looked at your channel and seen it!
