Hi..!!
Few days back I got a three phase BLDC hub motor from my friend. He asked me to make a controller for that. But I dont have the datasheet of that motor. and for deciding the PWM input signal I have to know the time constant of the motor.

Can anyone tell me how to measure the inductor of the motor without using LCR meter...??
