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.

Excelente zafra yildiz desde Colombia congratilaciones por tus aportes a estos circuitos prácticos y sencillos

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.

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...

Muy buen video!!, te faltó ver el torque que tiene. Saludos 🖖

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.

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!

Fajny temat latwy do zamontowania jako silniczek do roweru z odp sterownikiem i bateriami 😊

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

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.

Thanks sir ur this video solve my big problem now I can complete my project thanks again

Thanks Zafer for the excellent posting! 👌 Could you next time highlight the circuit sketch as you solder on? It makes it easier to follow!

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.

Excelente , estoy maravillado , que con tan pocos componentes se logre , estos resultados, felicitaciones, ..

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

Tebrikler hocam çok verimli bir çalışma olmuş

Kral doktürmüşsün yine emeğine sağlık 💯💯💯

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?

cara ta pra existir uma inteligencia igual a tua vou ate a suecia pra falar pros caras la de dar o premio NOBEL,,parabens,, outra coisa voce tem pra vender estas baterias azul ,,,acho que umas 4 dessas da pra abastecer minha casa de energia o mes todo,,,agradeço a ideia inovadora , o mundo nao vai mais ter falta de energia eletrica

Era o conhecimento que eu mais precisava.Obrigado.

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.

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!!

Очень хорошо автор показал всю суть. Спасибо за видео.👍👍👍🛠️🛠️🛠️🌟

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.

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

Very simple. thank you

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.

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?

Sir you are very clever in electronics.salut sir.i like it.india.

I made this circuit and it works well thank you

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.

Achei a ideia deste projeto muito bom e gostei também dos comentários um abraço ilustre amigo

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.

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.

Wow you are great 😌

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.

Nice work, I just wonder how it performs under load and may be higher voltage.

Ai , sim parabéns 👏👏👏👏

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 .

Bunu alatetörün diyot tablası nı iptal etmeden çalıştırırsanız 12v bir Akü hem altetnatörü Çalıştırıp hemde aküyü besleyebilir ve elektrikli bir bisiklet yapılabilir bence.

Muy bueno , para un alternador con conexión triangulo del estator como tendría q ser el conexionado

Je remercie surtout le présentateur de youtu.be qui présente ces séquences. Ce n'est que du bonheur.

Selam Zafer bey ( ESC ) bağlantıları benzemiyor. Sadece ( ESC olarak bağlantıları 5v servo test, amper güçleri, pil bağlantı ve çıkış 3 faz ) Alternatör direk 3 fazı bağlamak elektrik olmayacak manyeti pil hariç... Başarabilirsen milyon değil MİLYAR kişi izleme rekoru çıkarır ve Kosgeb Ar-Ge size çağırabilir ve ödülü alabilirsin. Çin den şipariş durdurur. Tabiki burda Pilsan ve fırçasız motoru açıldı. Sen ESC için Togg fabrika gibi devlet sizede açabilir. Haydi bitir şunu ÇİN i

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.

Wow spectacular.good job brother..!

This idea would be awesome if some tech or scientist could make this a free power supply unit. The idea is cool of a brushless system.

Мастер навесного монтажа

Güzel çalışma olmuş ellerinize sağlık. Bu sistemi birde normal rc lerde kullanılan fırçasızlara deneseniz muhteşem olurdu ama gerçekten emeğinize sağlık olsun

Muito bem. Gostei.

It may be useful for small handy works. Let’s see the output power and discharge rate . If it’s better then we can think more on it. Technic very 👍

Я так и не увидел, когда из генератора достали щетки, чтобы он стал безщеточным

Nice! Muito bom mesmo. Só uma pergunta, nessa configuração o motor fica com quantos HPs em média?

Ellerinden sağlıklı helal olsun teşekkür ederim

Sous les IRF, il serait préférable de mettre de la pâte thermique avant de les serrer sur le dissipateur. Sinon tuto clair et net. 👍

К ЭТОЙ БАЙДЕ НАДО ЕЩЕ, ПУСКО-ЗАРЯДНОЕ НА 20А ПОДКЛЮЧАТЬ - ГЕМОРРОЙ, ЛУЧШЕ ДВИГАТЕЛЬ б/у на 220в переобрести !

Sabe me informar , qual é a potência em HP que vc tirou da saida do eixo ??

Спасибо!!! Отказался от этого!!! Запустил, рукой, когда дал питание через балластное сопротивление. Сейчас хочу собрать на контроллере "MTD6501C"

wow very nice thanks. So THIS is how yuou build a simpler controller ? I love it.

عاشت الأيادي عمل راقي جدا جدا

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??

다이오드 항복점을 이용한 발진회로 멎진 아이디어입니다

Luar biasa komponen kecil untuk manfaat yg besar

Привет! Зачем 3,7V АКБ? Можно подключить к тому же питанию 12V через мощный резистор или лампочку! 😊

You didn't take out the brushes. so its not brushless

Great project and amazing soldering skills! Congratulations 🎉🍾🎈

Thank God ,youre genius, and hope to see more of your ideas,thanks

How efficient is this type of conversion ??? How powerful is an average alternator 120 amps compared to a electric motor Sir ??? Thanks

can this will be used for making electric bicycle

Благодарю за схему.Повторить попробую.Интересная штука.

Mantap luar biasah

👍👍👍

Что то я так и не понял, что заставляет транзисторы поочередно открываться?

Good job, thanks for video!

Could you use this idea to make an electic bike, using the gears of the bike and this motor system 😀?

не бесщеточный а щеточный так как ты щетки подключил, без щеток он бесполезен если только магниты поставить

Судя по видео у него одна из проблем, ограничивающая применение, он сам не стартует, его надо принудительно крутануть в ручную.

Be very careful to overspeed the bearings in any aplication. The chans for a disaster are likely eaven overspeed with only 1 rpm over the bearings maximum speed designation... Othervise, thanks for interesting konversion of the generator.

Hola gracias por tu trabajo lo voy a usar para un alternador de automóvil modificado con imanes permanentes de neodimio.

Really interesting!!! But it is even more exciting to make the engine (alternator) work in reverse as a "dynamo". Just so we understand each other!!!

Teşekkürler elinize emeğinize sağlık.

Что-то многовато 200Вт для холостого хода. Интересно, момент наверное не плохой на валу будет. Позновательно, в любом случае. :)

Teşekkürler meslektaşım. Eline ve gönlüne sağlık.

Elinize emeğinize sağlık. Güzel bir paylaşım olmuş. 👍

красавчик. давно искал такую простую схему решения. СПАСИБО ТЕБЕ.

it work for me! thank you!

Very cool, I'm a complete beginner in electronics, would you have a step by step on how to do this! About this piece that is used to increase or decrease the speed, would it have some way of being automatic, via radio frequency, wireless, bluetooth, in some way that I can change the speed at a distance that is short or even via arduino, because of the battery? Since you are testing with a bench source

Os melhores videos sao os dele 👋👋👋👋👋

çok iyi olmuş elinize sağlık :)

Elinize sağlık. Güzel çalışma. Buradaki sürücü aslında Royer osilatörünün 3 faza çıkarılmış bir versiyonu. Trimpot ile mosfet Vgs gerilimi ayarlanarak aslında mosfetlerin Rds dirençleri ayarlanmış oluyor. Burada dikkat edilmesi gereken nokta, düşük Vgs geriliminde yani yüksek Rds direncinde mosfetlerde yüksek Rds*Ids^2 kaybı olacaktır. Bu da düşük devirlerde yüksek ısıl kayıp anlamına geliyor. Soğutucu yeterli olmazsa yüksek çalışma zamanında mosfetler yanabilir. Yüksek devirde sınırlı hız aralığında çalışma koşulu için basit ama etkili bir sürücü.

Zafer usta güzel oldu bir sürü mosfad yapıver Parası göndereceğim ellerinden sağlıklı ve teşekkür ederim kolay gelsin görüşürüz

Ты большой молодец .Лайк тебе милый человек .

hocam semasini da koysaydin on numara olurdu ,eline sağlık

Çok güzel abi.çok iyi bir faydali video.

PARABÉNS belo trabalho

boss,,,,,you are genius person👍👍

Wow, very brilliant idea how many amps of current is the motor running with

Nice info, thanks for sharing :)

Good project!!!what is a battery use for?, it is needed in circuit? thanks..
