A helpful hint for you videos: if you will smear a very thin layer of SMD flux-paste over your solder board (not so much you fill the holes) and all component leads, you will get much quicker wetting of the solder to the connection. During a normal solder operation, you are actually oxidizing the connection because of the elevated temperature, and the solder balls-up waiting for the solder’s flux to heat up enough to become active to overcome that oxidation. Since the layer is so thin, it cannot be seen. When I make PCB’s I smear them with SMD flux-paste to keep them from oxidizing wether I tin-plate or not. I then usually wrap them in cling-wrap for longer storage. Give it a try, think you’ll like it! Anyway, great video!
@@gamesnic Enough? For what? To make it wet decently? News flash: it wets HORRIBLY compared to 63:37. Awful stuff, almost as bad as Archer (Radio Shack) fluxless solder from 1975.
reading the comments and an answer you gave about the red wire you put on the common where the three coils meet and you said you had converted from delta to star... I tell you that these motors are always in star and that for them to be in delta we must separate the three coils and remove them from the common and joining each one with the end of the other you get the delta connection...
leyendo los comentarios y una respuesta que diste acerca del cable rojo que pusiste en el común donde se juntan las tres bobinas y dijiste que habias convertido de delta a estrella... te cuento que estos motores siempre están en estrella y que para que estén en delta debías desunir las tres bobinas y sacarlas del común y uniéndolas cada una con el extremo de la otra obtienes la conexión delta... traducción: reading the comments and an answer you gave about the red wire you put on the common where the three coils meet and you said you had converted from delta to star...

Actually you are right this motor was star type connected, I just added the red wire as common connection. Your answer made me think a lot, but you are right, thank you👍🙂🤝
that was a high quality video! I was wondering how only 3 mosfets manage the transition between the 3 phases of the motor, an explanation of the circuit would help, thanks.
@@abraxasivo yeah im not convinced...lots of dudes these days are just getting click bait,, that schematic makes no electrical sens and does not show input or output connections so it looks like it just is going in circles..
Excelente video ,,estaba buscando fabricar un controlador de un motor de overboard casero ,,ya que aqui donde vivo no venden controladoras comerciales ,,,y la unica opcion es fabricar una casera como la que muestras en el video ,,la duda que tengo es servira para poder hacer un scooter electrico casero con un motor de overboard ? ,,y la otra duda es cual es el rango de voltage y amperaje con el que se le puede alimentar a este controlador casero ,,agradezco mucho si respondes mis dudas ,,,saludos desde el salvador
Tengo un motor de ventilador de aire acondicionado invertir, dice que consume 35 wats y el voltaje en la etiqueta es de 310 voltios. Este control podría servir para hacerlo funcionar? Alguna sugerencia?
hola exelente elvideo de montaje voy a hacer el circuitopara ver si funciona por que lei muchos que no creen y no esplican por que ademas pretenden manejar un auto electrico o jumbo jet con un circuito de experimmentacion exito y salud
I'm watching from Russia. Well and qualitatively done! Simple and clear! Respect to the author! But, I'm not very good at electronics. Therefore, the author, please tell me where the INPUT and OUTPUT to the motor are in the scheme?? . Смотрю из России. Хорошо и качественно сделано! Просто и понятно! Респект автору! Но, я не очень силён в электронике. Поэтому, автор подскажи пожалуйста, где в схеме ВХОД и ВЫХОД на мотор??
@@rusticagenerica I replaced all my 16 (whatever mosfets they were as numbers were removed) as close by lightning static blew the amp, I saw the flashover. I used IRF520N which ended up being better but had a higher biasing voltage. Ones I corrected for the new bias gate voltage it was distortion free. The originals were a bias voltage of 1.5 or abouts as there was only 2,1 volt bias before I changed the appropriate resistors to bring the gate voltage up to 4.2. Amp is better than before now a lower input to get same out. It is a HF RF amp.
How did you manage to get your power in if it a three phase delta ànd it only three cables coming out as your supply output feed or load, May I know your positive input then ??????
Thank you🙂🤝 The positive cable is connected inside on common point of this star type motor. The voltage is from 8 to 18V because you have to put zener diodes between Gate and Source
Hello friend, first of all, thank you for sharing. I have a question: In this type of circuit, every time you turn it on, do you have to give the motor a "push"? Or does it depend on the type of motor, such as HD or CD/DVD ROM?
muy interesante amigo, tienes un nuevo suscriptor, voy a probar de poner un PWM de voltaje como fuente de alimentacion y arrancar en 8 voltios. abrazo.
Wow, It´s a great project, I have a question ...what kind of motor is? 12v?, it is brushless? it was interesting to know. It have many potential applications. thanks.
Was a brushless motor type Delta with 3 cables, but i converted it to a Star type with 4 cables. I connected the red cable inside to a common point of the 3 phases to work with this circuit
Ercan ustam bunu çay toplama makinelerinin motorunu güçlendirmek için kullanmak istiyorum. 24 dc küçük motoru var. Üç çıkışlı onu dört yaptım. Kendi sürücüsünü iptal ettim sarımı bayağı kalın olmasına rağmen çok zayıf kalıyor sürücüden olduğunu düşünüyorum. Yanlız gelen voltaj 24 volt ne yapabilirim? Biraz bilgi versen ülke ekonomisine büyük katkı olacak bizde yolumuzu bulacağız İnşallah. Bir sürü atıl cıhaz var kullanamamışlar.
Ok i think i sussed it out the red wire goes to the center of the star wiring it has to be added separatly ,but he doesnt tell you that ,it is possible some bdlc motors would require being changed to star wiring arrangement if they are different,
this isnt a circuit id recomend for scooter or ebike as it will be extremely noisey ,like load wineing as spinning up,and will be bit jerky and erratic,due to lack of hall sensors for rotor position, but as a fail safe ,it be ok \
Direct from Marituba, Pará Brazil thanks for the video, I would like to know if this controller is the battery or if it is connected directly to the electric grid? I would like you to make a 48 v14 Ah battery model is it possible? From also
@@ErCanEverything I would also like to know, friend, how many amps can I get from this circuit? Would it be possible to move an electric bike motor, for example?
@@Persanity It can't. But it is possible to add a switch that switches the coils from the driver to a separate rectifier, but I don't think it's worth it.
Depends on current draw. Higher current will attract the rotor faster, resulting in faster switching. This speed up will continue until friction limits the output speed, and thus switching speed as well. If there wasn't friction, it would keep speeding up nonstop. So, the frequency can vary from a few Hertz to hundreds of Hertz..
Hall sensors are in place but I have not connected them and there is no additional controller. But I connected 1 extra cable to a common point of the three cables, this red cable goes inside the motor and is connected to a common point and that's.
Vienkārši un labi! 👍 Varbūt pamēģiniet pielikt kapacitāti 47μf uz ( D1,2,3 katodiem pret kopējo mīnusu) lai samazinātu palaišanas strāvu ieslēgšanas laikā?
Thank you very much! This is a good idea, I will try it. When starting with a battery 2 times burned out transistors, then I tried with controlled current from the laboratory power supply.
hello is this a multipoint unipolar motor or it's a bldc motor star connected with common neutral point ? and how is the driving switching sequence produced?
Hello this BLDC motor was Delta, but i turned it into a Star with a common point. And driving switching sequence becomes the help of the connected resistors and diodes. When one transistor closes the circuit gives a signal to the next transistor and begins the endless process of rotation.
لو أنك صورت ما فعلت داخل الموتير من توصيل الملفات واخراج الشريط الاحمر لحصل النفع بشكل اسهل عملت الدائرة واوصلت الاشرطة كما فعلت انت ولكن لم تعمل لو انك تعيد تصوير هذا الفيديو بشكل اوضح ولك الشكر
The voltage probably depends on the motor, and the direction is determined by the resistors and diodes. The motor should only run in one direction. To reverse the direction 3 diodes need to be swapped with 3 resistors and installed in the proper orientation.
Der Schaltplan sollte noch einmal überdacht werden. Der einzige Anschluss ist "GND" (Ground). Es gibt keine Motoranschlüsse und auch keine positive Spannungsversorgung. Man sollte schon auch das zeichnen was man lötet... Grundsätzlich finde ich es aber super, wenn ein Schaltplan gezeigt wird! Es gibt hier bei RU-vid viele Beispiele ohne einen Schaltplan - leider!
