bldc motor

Hello there, I've been planning to build an ESC from scratch for my BLDC motor, for an quadcopter project, and I have trouble figuring out the right commutation methods for design, I did some fair amount of research and found the most methods of control to be sensorless( as there are lower...

Hi all! I am new here, so please guide me. I am currently working on a project which involves working with H-bridges for motor control. It is required that I am able to wire up the circuit and make it work. The only problem is that I am a Mechanical Engineering student, so I have no knowledge...

Hi i have window cleaner ....problem is that when i on it the bldc motor not running ..i dont know if its a problem in bldc or pcb hardware ....i change the bldc drone motor with esc driving its beep like starting but it not rotate before there is small bldc motor which has 5 pins in which 4...

What should be the gate-source voltage waveform of the high side MOSFETs in a brushless motor drive with a trapezoidal control method? Are these parts marked in red in the picture above normal? There is no such thing at the bottom side MOSFETs Schematic: When I reduce the value of R47 and...

Hi i have a 24V BLDC motor. I want to rotate the motor certain angle or laps. The motor have 3 pin that "+", "-" and "GND". I'm not sure what kind of ESC i need use for position control. I found some ESCs but these ESCs have different pin names that "U", "V", "W". What kind of ESC do i need use...

Hi, I hope this is right forum, if not please let me know and I will post it under General Electronics Chat or Power Electronics I have a working board that we are unable to stabilize. By that I mean some boards get burned with no apparent reason. The system is an outdoor cleaning robot for...
