Excelente zafra yildiz desde Colombia congratilaciones por tus aportes a estos circuitos prácticos y sencillos
C'est extraordinaire ce qu'on peut faire avec tous ces éléments qui sont d'une richesse inestimable. Ce n'est vraiment pas un secret. C'est que de plus en plus les gens vont s'intéresser à ça par la force des choses. Surtout pour ceux qui ont déjà une bonne base dans l'électronique ou l'électricité soit automobile ou industriel etc...il faut aimer vraiment ça et être derrière le plus souvent possible. Se documenter surtout. Se faire aider pa ceux qui ont une plus grande connaissance sur la question. Ce qui fait qu'on rentre de plus en plus dans un monde de l'intelligence artificiel si j'ose dire au présent et surtout pour le futur.
I really like what you have done and how you teach how to do the conversion. Can you show how to do the same conversion with a much large alternator for a small motorcycle install ? I have seen very large alternators of big trucks and even 36 volt from forklift trucks...
To Mr . Zafer Yildiz , thank you in advance for a helpful reply. I am sure many others would be happy to get your reply.
For me, it would be a Tution in alternators as well.
Awesome project , as many others. A but of an explanation of what each of the elements does would be very useful for beginners.
Also, what’s your soldering iron model? It’s awesome!!! I wanna buy it!
Muy buen video!!, te faltó ver el torque que tiene. Saludos 🖖
Excellent circuit! Suitable for many applications. + wire is connected to center of star or y . He is using N channel Mosfets as low side switches, making it unipolar. It would seem diodes /resistors are directing back emf from adjacent phase for gate drive.
True !!! This video will be very useful in pumping water using only DC current which is way cheaper than being connected to the grid. I can only imagine its extensive applications.
Can this work in a Delta configuration?
@@ArshaansEdits Nope, four wire Y (Wye) connection only with a common connection as well.
do you know of a circuit that does work on delta? cheers@@imnotbeluga007
I'm looking for literature on under standing electrical components an electrical diagrams do you have any suggestions
Gracias @ZAFER YILDIZ por compartir tus conocimientos ¿alguien sabe como se llama el circuito, documentacion o informacion de su funcionamiento? me gustaria estudiarlo mas a fondo, gracias
A very nice circuit! But look at the power consumption! It takes up to 200W without supplying any mechanical output energy out! So, where is those 200W going ? I believe that keeping it on the speed takes about 50W max, it rotates freely. So, the rest converts to heat. I don't know, what's heating, whether it's the switching circuit or the alternator itself, probably both, but I believe that running it on such power for longer time will make it to blow. It's possible that the alternator has enough air cooling so it will survive it, but definitely, the efficacy of this construction doesn't look too much ecological. It would be also interesting to measure the mechanical output power it's capable to supply and the consumption it takes during it, it's possible that the efficacy will improve under load.
With such small wires. I can't imagine a very high output. Torque = boom

Is there a way we can get the battery to charge from the same alternator
@@gamingnijer5368 nope. that thing is working as generator or motor.... if you turn it it is generator... if you give it power, it turns and it is motor. it cannot be boh at the same time..... but you can have two of them, one as motor one as generator and KILL the second law of hermodynamics, (that is fake), and generate a permanent motor generator that generates electeicity... there are lots of them on youtube. how many are fake? how many are real? second law is fake or real? you need to test to see the answers.
No

Thanks Zafer for the excellent posting! 👌
Could you next time highlight the circuit sketch as you solder on? It makes it easier to follow!
You are unique idea man sir very very good in all of your project and you teach us every day so we pray to God a special knowledge for you thank you sir very much.
Very simple. thank you
First of all, Kudos for a very clever and simple circuit. But I think a little explanation of how it works would probably clear up some confusion, and probably disappoint those who are ready to try and put this on their DIY e-bikes.
The trick with any 3 phase motor is how to commute the current to the different windings in the proper phase to make it turn. This simple circuit relies on the fact that the power supply he used is in constant current mode. (note the red LED on the power supply labeled CC) When the current in the active winding reaches the 10Amps current setting of the power supply the output voltage drops and this causes the circuit to switch (or commute) to the next winding. This means that the output voltage of the power supply has a very large voltage swing on it. It would be interesting to see the output voltage of the power supply on an oscilloscope as the potentiometer is adjusted. This is how he can get it to work without an ECS.
The main function an ECS is to manage the winding commutation. Instead this circuit accomplishes the commutation by combining the saturation effects of the motor windings with the current source capability of the power supply and some simple diodes and resistors which combine to make a 3 phase oscillator. Because the power supply output voltage has a very large AC component to it, and the field winding of the rotor is attached directly to that node on the alternator, the battery is a clever way to excite the field winding. Trying to design a circuit to control the field winding from the same supply would probably be a bit more complicated. In a car alternator (as opposed to a generator) the output voltage is controlled by varying strength of the rotor magnetic field (current in the field winding) since the speed at which it is rotating depends on how fast you want the car to go. On the other hand, The output voltage on a generator is proportional to the speed at which it is rotating.
So basically, you can't run this circuit off of a voltage source, like a battery, it needs a relatively constant current source.
Как хорошо что так много людей которые вообще не понимают электронику судя по коментариям.нам хоть работа есть
You mean they can put some switching transistor with a large inductor as a current buffer. And control circuit to keep voltage in 12V level. All this as pre circuit before driving this DIY. Thats right?
Add 12 alternating polarity permanent neodymium magnets onto the rotor and you remove the need for the battery.
I am afraid your wrong, I run this type of controller in CV mode for 3 decades. The reason its in CC mode is do to the low impedance windings on this generator, its low so when its generating 30~40A it gets less hot, if you want to run this size motor off say CV of 12v, you need three $1 100W power resistors from alixepress, this will limit its output power.
They lie, it aint no brushless motor.
Parabéns sou seu seguidor de tempos Parabéns novamente por simplificar outra vez coisas boas pra todos nós conheço alternador com essa explicação vai facilitar a minha pesquisa sobre o assunto importante prá nós que gostamos do assunto valeu
Montei esse circuito e não funcionou , caso vc tenha montado e tenha funcionado pode me dá uma ideia ?

Ai , sim parabéns 👏👏👏👏
Excelente , estoy maravillado , que con tan pocos componentes se logre , estos resultados, felicitaciones, ..
solo es prototipo
Era o conhecimento que eu mais precisava.Obrigado.
Vou tentar também 👍🏻
Oi Rodrigo, eu moro em Recife e gosto muito de eletronica. Esse turco é demais nos projetos. Vou tentar fazer um circuito desse aqui.
Já montei um com ESC e tem pouca estabilidade, não dá pra tocar uma máquina. Vou testar esse amanhã
Quem montou um me fala se funcionou
@@alceugaspar3388 Com bateria de carro normal não funciona, só com fonte de alimentação semelhante ao mostrado no video. Para fazer o chaveamento dos mosfets e girar normalmente o eixo do rotor, é necessário uma sequência correta programada, como por exemplo atraves de um micro controlador, que ligado à drivers, dispara os mosfets na sequência correta.
Thanks for all your very useful projects. Your channel is one of the best that I have ever encountered. One thing I like is, you make me think and not only watch. More power to your channel 💪💪👍👍👍👍 Looking forward to all your new uploads.

Nice job!
Novice question: if the alternator is used in this setup, can it be used the other way around, to convert mechanical energy into electrical energy from a brushless motor?
Brushless DC motor is actually a synchronous motor. Thus, the angular position of the magnetic field of the permanent magnet with respect to the magnetic field that rotates with the excitation frequency which is the oscillating frequency of used three phase Royer oscillator, must be fixed at a certain value in order to produce useful torque and to maintain the rpm. If you notice, at some powering up instances, motor shaft does not turn at first, shakes a bit, and after giving some initial rotation, fields are synchronized and the motor accelerates. In classic drive schemes, Hall effect sensors give the ticks to be synchronized or ESC handles synchronization tracing back emf voltages on three phase windings. Moreover, supply voltage can not be reduced below a certain threshold voltage that is the threshold of the Mos transistor, and therefore circuit actually can not handle low rpm/high torque drive. To sum up, driver circuit is simple and effective at high rpm/low torque applications with some initial triggering at start up. It should be improved to cover mentioned problems to drive at low rpm.
Well put
hola se puede llegar a rpm cero o es complejo realizar un controlador de velocidad para estos motores y dar aplicaciones en pequeños modos de transporte como bicicletas ? saludos muy bueno tu canal
No da bien los datos
Ni pone diagramas
Good job, thanks for video!
Ellerinden sağlıklı helal olsun teşekkür ederim
Elinize sağlık üstat düşük devirlerde tork üretebiliyor mu acaba
Beautiful. I like it. The alternator is a cheap way to get a powerful 3 phase motor, and your circuit is simple, cheap and easy to understand and build, so it's definetely worth trying. I previously used an Ebike ECS because it was also quite cheap and offered many other options. It worked like a charm, but the documentation for the wiring were very sparse. I like yours because I can modify it as I please.
give it a try and let me know if it work for electric bike
Just use more batteries to power the alternator exciter coil lol...
Elinize emeğinize sağlık. Güzel bir paylaşım olmuş. 👍
Hayretle izliyorum videolarını abi. Gerçekten çok başarılı. Helal olsun sana.
Olá ZAFER da Turquia,
Excelente circuito muito simples, é o que eu queria, 3 Mosfet IRF3205 com alternador de carro. Vou tentar fazer aqui no Brasil.
Congratulações e muitas felicidades pra voce aí na Turquia.
Sera que funciona mesmo
@@meliponariomeldocerrado
Acabei de fazer o circuito, segui exatamente o vídeo só no lugar dos Mosfets IRF3205 usei os IRFP 250N
que havia removido de uma placa de um inversor , funciona bem ruim na partida aquece os mosfets
mas funciona com bom torque depois que arranca!!
A titulo de experiência é bem interessante mas acho que no uso não vai suportar por muito tempo!!
@Lucas Teixeira da pra por mais mosfets em paralelo vai suportar mais corrente na partida
It doesn't work I tried it already
Obrigado amigo ......estou estudando sobre o alternado para tranrforma-lo em motor brusheles para bike eletrica ....faça mais vídeos a respeito ....lógico que vc mesmo montou o circuito para girar .....o bom é com uma controladora de 1500 watts daí terá potência de verdade .
olá amigo, vc acha que seria possível dois alternadores adaptados como motores moverem uma moto? Gostaria de adaptar. Gostaria de saber, além de duas placas controladoras de 1500w, o que deveria comprtar para ter confiabilidade?
it work for me! thank you!
Teşekkürler elinize emeğinize sağlık.
So the alternator is in star connection, am I right? My question is.. How many watts is the maximum can handle the controller or the mosfets? Can I input a 48 Volts 1000 watts?
Мастер навесного монтажа
Zafer impressive! I have seen an alternator turned into a couple of different things in many different ways but until now never a motor. everything you did makes sense just never thought of it. Pretty Cool!!
Teşekkürler meslektaşım. Eline ve gönlüne sağlık.
Последовательно с обмоткой подмагничивания проще включить лампу накаливания от авто 10-20 ватт в зависимости от мощности "мотора". Тогда не нужен литиевый акку и 2 питания.
сколько часов он отработает
Видел не мало роликов по єтой теме, но сдесь я не понял....всегда распутывают концы фаз, ищут начала и концы обмоток, а тут он оставил фазы как есть, да ещё и впаял дополнительный провод, и что за место в которое он впаял? и такой вариант имеет место быть или те "класические" варианты всё же лутше?
@@crenimrt268 Четвертый провод, это средняя точка трех обмоток. Вместо лития на подмагничивание, я ставил две батарейки типа АА. В зависимости от напряжения, у меня менялся силовой момент. Хотя лучше всего два провода на щетки подключать к общему питанию через лампочку на 10 ватт 12 вольт. Генератор брал от Волги, у которого на валу только щетки, то есть с внешней таблетки, а не встроенный. Точно так же работает и генератор от 412 Москвича.
This is an excellent contraption Zafer. Congratulations. How's can I regulate the current supply to correspond to the voltage I require? For example, 19V is what my laptop needs, but I noted that your gadget produces 10A at this rotation level while my laptop requires 3.4A. And may enquire the use of the AA battery? Is it for exciting the alternator field? How long would this battery last before needing replacement? Is it not possible for you to setup a self-excitation circuit so as to eliminate the need for this battery? Thanks for the knowledge.
При чем тут твой ноутбук😂😂😂 этн работает электродвигатель, который был генератором🤣🤣🤣
Yeah, I couldn't see how the circuit would trigger the MOSFETs unless there was some funky zener like threshold but the diodes specified don't have that feature.
Also, note that he never shows startup behavior.
This is just a driver for a motor. This circuit REQUIRES an power supply.
This WAS an alternator in a car. Now it is used as a motor. Ir produces NO electricity, consumes it.
@@ayedurand This whole circuit seems a little bit shady, to say the least. If it is "brushless", why does it need to "power the rotor"? How does that power get to the rotor?

Hello Zafer, your project is interesting. The rotor rotates smooth, even in low speed in 2000rpm. In your one comment below I read that you not recommend it for an electric bicycle becouse the its efficency is low (Shrikant Bhai Bhosale). What can I do to improve the efficency?? If it needs more volatge it is possible to use batteries for 24-36 volts??
You use a different motor.. it is not suitable for powering a bicycle.

Thank you my friend
Ты большой молодец .Лайк тебе милый человек .
I think this configuration will work on any three phase AC motor, provided that you supply it with a decent amount of current., because car alternator is simply a 3 phase AC generator.
can this will be used for making electric bicycle
In fact, I do not recommend it, the efficiency is low, but if you can afford it, of course it will work.
Yes you can. This is the alternative of ESC.
You didn't take out the brushes. so its not brushless

Привет! Зачем 3,7V АКБ? Можно подключить к тому же питанию 12V через мощный резистор или лампочку! 😊
It a scam
in this connection, the battery will be very happy when the alternating current induced from the stator starts to flow into it, but perhaps it will not explode, because it will soon stop exciting the rotor winding.
чтобы ротор оставался стабильным во время изменения мощности, потому что он потребляет 10 ампер и полностью использует источник питания
