HELLO. This trial is great. Everybody is bothered from rectifier and voltage regulator, it sound like protection from malfunction but it works not to get big energy from alternator. Your trial is a breakthrough. If you turn the pulley faster by machine, this alternator can have much more voltage and current. I was encouraged.Thank you!
Well, the explanatory was quite good and clear to understand how a car alternator could be modified as a generator.
You do great things with electricity. We all appreciate it which is why we watch. Maybe consider background noises in your videos as they make it hard to hear you (for us old folks) and distract from the information you deliver. Thank you again!
Thanks a lot !! In January i am planning on extending my Lab area so that all the upcoming videos are recorded inside the lab coz its too noisy outside.
Thanks once again 😊
well done bro, i only wondering , how much watts / amp you get, because coil has been a thick size of wires so i didn't expect too much volts indeed
Hi Mr Electron...I am working on projects myself and have found your content very useful. I was wondering tho : could a joule thief circuit be used to excite the alternator ??..Joule thief can provide all kinds of voltages at high frequency (low amps?)and would be interesting to find out if it could work..Many Thanks to you..
please make a video on wind turbine alternator for home 3kw from induction motors usually used in water pumps at home
I think, your new tester should be set at AC tests so that it can read the output..
Parabéns. Esse gerador alternador funciona melhor se incitar o magneto e fazer o teste de quantos quilos ele aguenta, alguns 6 kg ou 8 kg, e os ímãs de neodimil devem ter o mesmo magnetismo, aí sim gera muito, desde que tenha boa rotação.
Thank you for the cool build vid, A reading of the Ampere as well would have been handy but cheers for what you did show!
Which size of magnet requer for this project
Mr. Electron I’ve installed the Neodymium magnets 12mm x 2mm N 52 how to put the center back in with the strength of these magnets will not go in like the way you put it back together ?
i like how right before he pulls the string to test it he told himself "GO!" @10:30
hello sir electron ... your work is fantastic excellent the adaptation of the magnets in the alternator poles. but you should use that alternator as a brushless motor with a 1.5kwatts variable frequency drive, you could have an extraordinary electric motor. I hope you accept my advice. thank you good 2021.
Thanks for providing such fascinating info to your viewers. I appreciate all of your efforts. Sincere thanks for sharing this!
Neodimio alternator
Nice honest video thank you Mr Electron, I think the original electromagnet was much stronger than the Neos.
But no input energy is needed and there are generation now on much lower RPMs.
Nice to see you in live video always i see hands only. Your explanation is very important and clear I hope I meet you in 2020 I make a project in your guidance that is working nicely this time I am out of India so I hope I see you in real life thnx
Thanks a lot Inderjit. 😊
I think I will make one of these but drill the holes deeper and use 2 magnets per hole...just to see if theres a bit more voltage that way
Ya. That a great idea. I want to try that too.
Great.For 20 v output, is that too much for the stator?For 300 w power demand.
In my opinion you vidio is the best! Please keep posting! Thanks!
Saludos desde España!!!
Buen video...
Cuales son las medidas de los imanes???
Muchas gracias
Thanks brother. Pls let me know if I can comfortably spin this motor with 12v battery, use it to run a small alternator
Great job on the alternator mod.
I love it where do you get the magnet from please let me know
When you open the stator, are the 3 wires - star / delta configuration already ? Thx for sharing this :)
Star
Jesteś super. Pozdrawiem.
Appreciate your hardwork Bro, try to connect your generator motor to a Gym cycle or regular cycle Backwell and use step down transform or stepdown or stepup Module to Charge a 12v car battery, later it can be used to power the home appliances using inverter

I did the same as you. I got 29 volts and 0.3 Amps, which is too little to burn even the smallest 12 Volt bulb. That's why I don't believe you.
with that setup sir, can u still use the alternator to generate current/ to charge or a source to power an inverter?
Nice, Which size of megnets used in this project? Secondly wil it perform better in car whose you have got?
Very nice video, thanks for sharing
The rotor should have contained a larger magnet for higher flux density. The rotor is too heavy and more metal should have been removed from the same. Also you should have lubricated the same so that it rotates faster.
Good idea 👍 I like it
A quick way to drill holes with a consistent set depth, 1: find the desired depth 2: drill first hole to depth then stop drilling 3: with the drill bit stopped and in the hole, wrap some masking tape around the drill bit's circumference at the surface of the material being drilled 4: back the bit out of the hole and start drilling the other holes. The masking tape is easily removable, won't damage the bit and clean up is a breeze. Heat and tapping compounds might cause the tape to melt or slide off so you might want to think about using different types of tape or permanent markers/paint to mark the depth on the bit.
Thanks for the tip Cliff. I'll try it.
Don't waste time, just set your depth-stop on your drill.
Сделал красиво, покажи как это работает.
You should use a light oil when drilling with large bits like that, they will last far longer.
Great experiment..👍👍
Bravo !!!!!
Congratulations.
Nice work. Good to finally see your face my friend.
Cute...yea?
good job man, and God said, "let there be light!"
I would use a drill to help turn the alternator that way you can get a constant speed.
I’ve done this but I used N 52 for strength and wow the strength of those magnets do not want to allow me to spin it !
try ceramic magnets
LOL Ive got 2 bigger ones stuck and I cant get them apart
Mr. Electron excellent video.
Lekin jo bnaya hai bahut hi kamaal ki chij bnai hai
Even if u give 1500rpm u would only get 12- 15 volts. You have to use big neodymium magnet like n52. I have tried this type of convertion in half HP induction motor using n45 but the voltage was maximum of 20 volts!
hi friend! ? is what did you do with the middle short wire ? where does it go to i know you taped up the other grounds together and left them inside the copper windings, but what is the middle phase wire go? after its all finished!
aur name apne bahut achha rakha hai (MR.ELECTRON) WAH
for those of you wondering, the faster the spin of the stator, the more voltage.. the bigger the wire, the more amperage.
고마워요
@@sksdksckddn 천만에요
Thick wire for more current.
@@farrukhhasan7751 yes. And spin faster to produce higher voltage.
There is a limit as to how much thicker a wire can be as the current is not determined by the thickness of the wire but by the strength of the magnets, so if your magnets can only produce 1 amp then it does not matter if you have 1mm dimeter wire or 2mm thick wire it will only produce 1 amp or may be just a tiny fraction more due to the resistance to 1 amp current flowing through the wires, Power Generation is the product of the strength of magnetic field and speed of rotation, voltage is proportional to number of turns and strength of the magnets and the speed of the rotor. And nothing comes out of nothing, so if you wanted more power then you also need more input power to spin, (Torque)
attach high speed motor to it, then wire in a step up transformer on the output of alternator, test AC voltage out of the transformer.
If I was also a Monday morning quarterback I would say what your doing wrong and feel good about myself but I’m not. So keep up the awesome work. Love your channel.
Very good, tente retirar todo rotor e, faça um novo rotor de madeira com imãs de neodímio maiores! O ferro freia o gerador!
The set of windings from which power comes is THE STATOR as the winding is stationary.
You won't get the power from this as you would with an excited rotor winding and you can't
control the output either.
Dear help mere pas dynamo generator se nikala tha hai 2.75 yani ten se thorha km jis ka rpm 2750 ka hai is ko mien use krna chahta batery ya ups se kon sa motor lon ap bataden mere pas dc motor hai likin rpm oska km hai mehrbani karen
Very nice! I wish cars came with true generators...we might have to make one!
They use to! I have a 67 mustang that originally came with a generator. So did my 64 Ford F-100. I use to go to the junk yard and get the generator out of old school buses. The old AC-Delco indestructible. Used one to power a wind generator. Lasted about 8 years. Of course the auto industry can have things last forever! :o) Not to mention government safety regs and on and on. :o)
@@vhmccray3705 but was it a true generator? With solid magnets?
@@vhmccray3705 and yes, there's all sorts of excuses for making crap nowadays
Mr. Electron could you send me some info on how to properly construct one of those boards. I'm looking at making hand made circuit boards for a project I'm hoping will take off
What you have created is called dynamo, which is used in cycles till date. Flux created by permanent magnet is very less compared to electro magnet(field coil). Today dynamo bicycle hubs are available which produces 6v.
No tradotto italiano
Nice bro if u attached with fan it gives you more power
Somehow I knew for a successful test, a yellow voltmeter was needed !!
Nice job 👍
Hi Electron, this modification on the car alternator should produce much more energy,maybe some of the copper coils are in short circuit... 👍
Perhaps the magnets are not strong enough to generate more on this RPM? The electromagnet inside the rotor was pretty strong when the brushes provided power for it.
J'aime tellement tes interventions,tes compléments
I really like your work Mr Electron. Can this be also used as a brushless motor? Thanks
Upcoming video
Los imanes son demasiado pequeño para tener un buen rendimiento.🧐🧐
GOOD JOB 👍👍👍👍COOL 👌👌👌👌😉✌
Nie ma to jak przerabiać elektromagnes alternatora na magnes stały. Genialne. Tak na prawdę wcale nie . Magnesy neodymowe nie pożyją w tej konstrukcji zbyt długo bo szybko zostaną przegrzane. Lepiej było by wyprodukować osobno talerz z magnesami i talerz z cewkami. Lepsze chłodzenie prostsza konstrukcja. Język Polski. Też warto się go nauczyć
U don’t even realize how close you just got to a billion dollar idea. Thank you.
I do realise it 😃. Although i am more happy that you realised it too ....
buen trabajo saludos desde colombia
Very good, excellente!!!
Have 6 pin alternator, which one do I connect too, the 2 at each end & leave the 4 out
amazing !!! a great invention !!
Question how big are the magnets?
I found your vids a long time ago. I finally found you! Lol. I have a dead Alternator. It's a GM ( General motors) 100 Amp alternator! Half of the diodes have died. I bought a second hand unit and swapped in 15 mins at the wrecking yard, tested and drove off. Do I take the diodes out or do I replace them? I want to convert to your setup. I have 2 deep cycle batteries and 4 solar panels at 250 watts each connected to my batteries. I want run a dc motor I have lying around to power the Alternator. Any reply and ideas would be greatly appreciated! Cheers from Australia ! Subbed a long time ago but liked as always!🙂👍👍👍
what size drill bit you using,,also what size magnets,,,,and strengh of magnets....
Bonjour, Est ce que une plus gros alternateur donnera plus de puissance de sortie.
where can one get those small magnet some to buy?
This is asmr ,relaxing me
😀
nice video and tutorial is great and clear....
Well how you solve problem over charging lead acid baterrys? Do you add external voltage regulator? What wuld hapen if you use bouth magnets and field coil together?
Wuld they cancel ich other out as in magnetic field?
Good to put some baking soda on the glue for filling the gaps and assuring it dries correctly
what would be the theoretical maximum voltage for an alternator setup like this?
The breakdown voltage of the coils’ enamel coating, the amount of turns determines the base voltage and scales logarithmically with rpm.
Car alternators need to spin at very high revs to make even just 12 Volts. While on the car they will be 'geared up' and be running at 2 or 3 times the speed of the engine.
We are talking 10 to 20 thousand rpm - just to get 12 Volts
A much better conversion would have been to leave the brushes and the rotor coil intact and power it from a single diode connected from the output of the stator coil.
This would be after removing the original stator coils, noting how it was wound, then re-winding it with some much thinner wire.
This will give more volts and at lower rpm - making the resulting generator much more useful.
Rewind it as was, as a star connected 3-phase and connect your diode from one of the phases and back to the centre point of the star. Or make a 3-phase bridge if you prefer.
It will self-excite and the existing rotor coil will make a much stronger magnet than the permanent magnets ever could - giving you greater output.
Get as much wire into the stator as possible, every extra turn is worth more volts
Do not be greedy and expect mega mega output. For a machine/device like that, self-excited as it will be, do not *ever* hope for more than 200 Watts - but at least it will give measurable volts and useful power if built into a wind turbine.
Спасибо вам огромное за информацию. Молодец. Купил магниты, но я не решил ещё получится у меня это затея? Кто нибудь пробовал это сделать? Напишите. Ташкент. Мне 70 лет.
Nice work .. any magnet 🧲 and copper coils should generate electricity it doesn't matter what ! Am looking for self running generators ideas if you have any ...... !
Nice to see you bro🙂
Supper idea
thanks
I love these kind of videos, ggz pun jabi
hola, queria preguntar : funciona con bldc controller ?
y tiene torque?
English ?
En principios tecnicos, funcionaría, pero debido al reducido tamaño de los imanes permanentes, dudo mucho que tenga un minimo de torque necesario para impulsar cualquier cosa, el puro rotor genera un torque inercial muy grande en comparacion con el tamaño de los imanes de neodimio que coloco el hombre en esta publicación, en todo caso podrias colocar imanes mucho mas poderosos para asi poder generar mas torque, pero eso incrementaria mucho el costo de este motor, ya que mientras mas grande sea el iman de neodimio, es mas caro y necesitarás muchos, haz numeros eh investiga precios y te daras cuenta de que será inviable si es que quieres mantener los costos bajos, yo te sugiero que utilices los anillos rasantes/rosantes como estan, no es caro reemplazarlos y las escobillas son muy baratas, saludos.
Edit: Necesitarias un controlador adecuado para la versión de anillos rasantes/rosantes, aqui no funcionaria el BLDC ;)
The reason you hammered it(which did the rotor no favors at all) was that you had the rear bearing come out with the rotor which it should not do. You should have removed the bearing, cleaned the rotor, install the bearing into the back case, then install the rotor(after lubing the shaft in the bearing area.
Bạn làm rất tốt thật tuyệt vời
Does this brushless motor gives you more output power or same output? Is the input power the same for both types?
Output on this type depends on how fast the rotor is spinning and how powerful the magnets are. No input power is needed because it's brushless. Less power is generated for sure but also less is needed to generate something.
Are the magnets 15mm x 4mm?
Creative video,thanks :)
hi .actually the magnetic field of alternators are not normally constant and it changes according to the energy consumption . if consumption becomes high so the magnetic field will be higher to keep output voltage in range . i can guess that these small magnets can not give more than 20 % of that alternators energy capacity .
Very nice
So nice this lecture sir
Its alradey working befour on the d,c 12 volt so what is the right after you fet the magnet in side
I have a GM 1 wire Alternator 1987 TA and man it was dirty I have the Stator soaking in vinegar two lemon squeezed into it and baking soda after brushing it with a toothbrush !
Very good idea and you can test on sensor less bldc controller as bldc motor plz check it
Upcoming video
thanks bro
I'm going to try this thanks.
Please dont tray becouse this is alradey working 12volt
Very interesting and well explained but the small magnets set into the big surrounding area of steel, will not work. The upward facing pole of the magnet will be cancelled out by the surrounding steel acting like the opposite pole. So you will not have clear and distinct North and South poles!
