The idea of creating a brushless motor control circuit
Brushless motor speed control
Everyone has suggestions to make the circuit more complete
My ideas: czcams.com/video/se-RxeFEncY/video.html
Dear! Please make a hoverboard motor controller.
Hello
How much ampere this can carry.
@@lovenish7523 I haven't tried it at full capacity yet
@@D.creative ok
The Mosfet terminal D (middle one) and the screw hole metal are the same connecting conductor, it is important to show how isolation is done between the screw and the body of the heatsink. Otherwise all D terminals will be shorted.
I was thinking "wow, pretty cool" until you shipped out the custom soldering iron and then, that earned you a goddamn.sub
Mantaf nih bos.keteranganya tutor nya jelas pelan bisa dipahami.editan vidionya mantaf.bisa motong durasi waktu❤
dah coba blm lu bang?
Thanks. I'm installing this in my hoverboard to spin the liquid metal ring with some magnets.
أشكرك وأقدر مجهودك ، تحياتي لك من تركيا.
В 60х годах в СССР был асинхр.дв на ГТ403 на магнитофонах весна 202 тот был прорыв в радиоэлектронике желаю вам успехов
Excellent...
I just happen to have everything for this project, awesome one!
Thank you!
Did you build the controller and did it work for you?
Great job! Plus your build quality is art. Awesome!
Thank you!
Anyone also came from Greatscott's video?
Very nice video about bldc motor.voltes.control thanks sir
Nice video, nice technology, meaning full video...., Learning full video...
好嘢❗有料到❗谢谢你的视频。china HK
You somehow made the video, you made the circuit money, that's how you made it ..
You should use plastic screws with your insulations
There is white insulation washers that make it not short, otherwise it would not work.
@@Ozzy3333333 but he used metal screws which could touch the heatsink from inside the hole
@@matejgamingandotherstuff6484 he is using a special insulation washer, it keeps the metal screw from touching the fet metal tab, its hard to see in the video, but its there, these are very common in power supplies.
@@Ozzy3333333 but the screws are metal
@@matejgamingandotherstuff6484 and the washers are insulators = providing insulation, look them up, you will understand.
Thank you very much for this circuit diagram
this thing could power up my prop plane and thank for the tutorial
Love from India 💖
Excelente el video por su limpieza. Me acabo de suscribir.
The video at 5:49 suggests a star configuration for the motor coils. However, delta configurations are also common.
This circuit simply isn't compatible with a delta configuration. A delta configuration requires current to flow through 2 coils, and this only does one, and to the common central point.
You'd need 6 transistors and a microcontroller to control that - you've just made an actual ESC that you can control!
Thnx brother it's great job but i have question this bldc is for 4 wire connection witch named start connection please can you make tutorial to bldc for 3 wire who named delta connection... Thanks a lot of i like your videos 😉

Thank you Sir for the schematic really appreciate your knowledge base
explain where the impulses come from? If there is no generator?
Sorry, I figured out the circuit, it's a 3-phase multivibrator
But there are no capacitors! multivibrators need capacitors for reliable operation.
@@janami-dharmam You're right bro!
czcams.com/video/VUqVODNgOFQ/video.html
Did you build the controller and did it work for you?
Very cool! Maybe I'm wrong, but it seems that to get more Motor speed you are turning the Potentiometer knob to the opposite (left) side?
Another thing, is it not possible to stop the Engine completely? Thanks for sharing.
I asked you two questions!
Fantastic video l love it thanks.. super video me encanta mil gracias por compartir..
Thank you for watching!
Hi Sir author
Can u please anwer if mosfets IRF540 can be used instead of 3205?
Also, the diagram in the end of the video is covered by pictures of next videos.
Can you please put the diafram in a file and share?
I will try to software simulate this circuit to check other parameters and help to improve it
Thanks a lot for your effort and great work
Best regards

@@D.creative You are very kind and generous, sir.
God bless you
You just need to make sure the source drain and gate match on both transistors and you should be fine.
@@Fernybeme Hi, thanks for your reply. I have tested with both IRFZ44 and IRF540 and they bothe turn the motor at a voltage higher than 5V. I used 8V
@@pafunleal3849 awesome
URGENT!!! I am looking for an audio pre-amplifier capable of 300\400 times gain. There are several diagrams in the N.E. manual with explanations, and it can be nerve-wracking to stand there with formulas to be able to find the ideal Rx value ..... . The LM358 IC is great but I would like to know what is it capable of doing? What max results can be obtained? In short a noise or a voice at a certain distance .... . How to get it as close as possible and then run it through an 'AB' type amplifier. But what wattage is needed ....... ? Thank you very much.
This is very impressive!
I want to be able to do a scaled up version of this, for say a 5kw BLDC, to work for my boat conversion. I don't really know the 2nd thing about this stuff. Anyone willing to share their wealth of knowledge? I intend to use ebike-type parts but obviously throttle grip speed controller is t gonna cut it for a boat. A foot pedal could work, but is also not ideal. Any ideas?
GUYS, has anyone tried to assemble this, I've tried several, with several types of mosfet and none works, I followed the letter, from several different sites, and I came to a conclusion, FAKE. if it were that simple, you wouldn't need sophisticated drivers to run such a motor.
1.) He shorted the gate to drain of every transistor with a PN junction diode and then shorted the drain and gate of each transistor with a seperate resistor but with different combination.
2.) The potentiometer has no groud connection; it's Voltage input is with a resistor that is supplied through the signal out pin of the same pot.
3.) The drains of each transistors are free floating (idk if they are connected to the heat sink or something, because he's connected the bldc motor to the heat sinks! NOT THE DRAIN!)
Yeah so i think it's fake.
Hey but i found another video about the same concept and with same schematic.
Looks like that's working fine, maybe it does work.
Gotta try myself.
Edit:- czcams.com/video/nTgNCvQhwO4/video.html
@@amvkarthik would it works on delta winding?
@@user-f_y_m where will you give the +9V if it's a Delta winding?
IDK to be frank try it yourself and let me know.
Uhm I made the same connections on breadboard and I had no problem
Please do a video on three wire bldc drive circuit
Blue, yellow and red wires are sorted to each other. Hows it running!😢
How many amps can this circuit handle?
好嘢❗示范手法一流❗china HK
Thank you!
Thank you nice explanation, patient shot
شكراً على الفيديو المفيد اتمنى الاستمرار 🌺
All three wires connected with heat sink so close circuit ( connected together ) how it will work tricky video
Респект 🔨😎👍📽️🔥🏁🚩
Like you for the diagram! There is no 4.7 kOhm resistor on the diagram, but there is one in the video. Why ? I repeated it exactly from the video - it works, but the motor itself does not start - you need to push it. I supply 9 volts from a laboratory source. Why not 12 volt power?
Many thanks
I like it, i’ll give it a try
Wow thanks really helpful, please what's the rpm of the motor at 9v. Thanks in advance.
MAKE VIDEO ON BLDC FAN DRIVER
Nice work full support your channel
Thank you!
Nice
Nice but would like a follow up step by step how to find the right components.
4:44 what kind of soldering gun is that, where did you get it?
Simply awesome build loved it, just a question can this ESC start the moter from 0 RPM?? 👍🏻👍🏻 Superb video
It does in the video.
@@Fernybeme Yes surely it does but it does not bring it back to zero RPM post starting unless disconnected from power source, which actually should happen as there is a variable resistor or a potentiometer, when in closed position it should cut power to moter even if it's connected to power source, this is my concern dear friend 😂😂🙏🏻🙏🏻
@@Yaman-D-Chhaya ah, i see.
Well you should be able to by changing the value of the potentiometer. He is currently using a 100kΩ potentiometer in series with what looks like a 4.7kΩ resistor to ground. I believe if you swap it to 200kΩ or 300kΩ it should bring it to zero. If not you can probably use a voltage devider instead. The will change the input from a resistance based speed control to a voltage based one.
Also, he forgot to show it, but there is a plastic washer on every screw holding the transistors. If they are not in place it will skirt them all out.
@@Fernybeme Yes it surely can 😂😂😂😂😂
Why does this work, and how did you know it would, before building it? What causes the commutation? Does each section sense the electrical behavior of the next/previous driver/coil?
Good job please can give the circuit diagram of the of the system
Very cool project. Excellent build quality. 👏
3:08 I guess you can't replace the potentiometer with JR servo wire connector to stick it into the reciever and have working RC ESC?
Thanks for this
Thank Q brother
This is an experimental and simplified circuit showing the principles of BLDC motor drive. It absolutely isn't a working design for driving a motor in real life situations. It probably won't self-start, it will have poor torque characteristics and there is no protection to prevent overstress of the motor or the drivers. If you build this hoping to use it to drive a real motor with a real load then you'll be disappointed, just buy a commercial BLDC driver instead. If you build it then expect a fun science demo and nothing more.
Good
Very nice my
Nếu video có máy đo rpm để show min và max speed thì hay nữa bạn ah
Cảm ơn bạn đã xem video và góp ý.
I also watched various videos. The circuit is almost the same in all of them. I did. it didn't work. I checked again and again. to see if there is an error. Frankly, I couldn't find it.
can i use this with 12v battery as power source?
Thank you for content
Can we use 12v? And another question is the power supply is DC or AC because I've seen people are using AC to let it spin without ESC
We can use 12v. is the DC power supply. This circuit can be used for big motors: czcams.com/video/se-RxeFEncY/video.html
thank you for watching!
@@D.creative much appreciated your work
Se eu comprar um controlador de velocidade pronto ele vai funcionar?
Yeah sure
Funciona sim! mas acho que tem que escolher o controlador ESC certo.
thanks :)
Tanks for sharing.this circuit working for copier 24v bldc motor sim another video 12v motor you showing?
thanks for your effort, I did everything but the potentiometer doesn't affect the speed!.......and if I have a motor with three wires only how I could connect it?
Hay quá bạn, đỡ tốn tiền esc +1 sub
Can ESC be made with 2 mosfets and a thermistor . ??
Good job!!!. It would be interesting to achieve a minimum speed of 0 rpm, what would have to be modified?
Remove the power and you can get zero speed.
@@assassinlexx1993 that makes no sense.
@@luiscolmenares3454
Simply that no power means zero rpm . Now if it above zero then maybe.
@@assassinlexx1993 I repeat It does not make sense, what if you need 10 rpm and then accelerate it to the maximum?
@@luiscolmenares3454 but you asked for 0 rpm.. the person replied to you was technically correct
excellent 👌 what RPM can speed?
Good ❤❤❤
muy bueno, cuantas son las rpm mínimas que se pueden obtener?
¿ Como pude tomar una face directa del cuerpo del transistor, si los tres transistores están atornillado$ al mismo disipador de calor ?
Nice video! One question: how do I make it stop?
I've been looking to implement on/off burron to the slide potentiometer to use it as 0-100% motor driver and still need help
How about with 2 mosfet? Can its work?
Then what is use of Hbridge bldc driver....? Can you replay...what is difference
Red probe is positive or negative bro??
Это девушка в кадре?
🤗👏👏👏👏👏👏👏👏
Thanks brother i have an idea for Delta connection motor.
How to use this circuit in three wire hdd ?
Nice job bud ty.
How can this work the red ,yellow and blue are grounded together
Thanks for video, how many watt is the resisstor 4/7?1/4 or more?
I
Verry good!! does this Controler support load on it?
yes sir. Thank you for watch
Thanks Any easy circuit for Delta connection motor plz share thanks.
Very simple and nice!
the schematic in the circuit with the one in the video is not the same. it turned out that the diode was reversed and I followed the path in the video instead dropping the adapter and the hdd didn't work.
thanks for sharing your circuit. What is your input voltage?
Cám ơn video
Can you make the motor go forward and backward? And if you can do it; try to slow down the motor so we can see what direction is turning.
thank you for the video. How can I determine the appropriately sized components to use for an approximately 2000 watt brushless motor?
You do not want to use this for a 2KW motor,why, it don't have good control, and a 3hp motor you want control, at least I hope so.
Can you use this one at three face brushless motor wire
It is not possible because all three wires are connected to the same source which is connected to the that aluminium piece for cooling mosfets
Excelent !!
I've made it like this but it doesn't want to play, why? the motor is locked, it won't move. used motorcycle photocopy diameter 6cm 12pole stator 10 pole rotor
Does it matter how big the heat sinc (is sinc spelled this way?) Is?
Good work, electrical energy ¿? CA and DC??👍👍
I made it for DVD rom motor and it didn't worked, one of the mosfet overheats though, rest are ice cool. What' could be wrong brother?
Mạch này chạy tối đa động cơ bao nhiêu watt và ampe cao nhất đạt được là bao nhiêu
U, V, W van a los mosfet pero si todos los tornillos están conectados al disipador están todos unidos? Lleva algún separador aislante en el tornillo?
are isolated with plastic rings
What is the function of the diodes installed from the gate to the drain?
heatsink shorting those output!
