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.
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!
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.
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 😉
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 ..... .

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.
@@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.
i made the circuit and works very well with a bench psu were current and voltage are adjusted but when i connect it to a homemade 18650 16.8v psu motor stuck and not spin even if i turn it by hand. Should i add to the battery psu current control or capacitors or something else at your circuit?
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
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?
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:- ruclips.net/video/nTgNCvQhwO4/видео.html
@@D.creative Thank you for the amazing video... i finally made it work. For anyone stuck after youre sure the wiring is correct try increasing the amperage that fixed it for me :D
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
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?
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?
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?
Hi, I have just finished my mosfet esc as on your video but it does not work can you help me find the reason for this. When I give it power the hard disc motor stutters for a second and stops, if I turn the potentiometer it squeeks but doesn't turn, same with other 4 motors. Thankyou Donatello

Thanks. I'm installing this in my hoverboard to spin the liquid metal ring with some magnets.
The video at 5:49 suggests a star configuration for the motor coils. However, delta configurations are also common.
