I have a 390 DC Brushed motor, which actually came with a RC Car. I was trying to add an ESC to the the motor to control it through PWM Values. I had connected it to a 20A rated ESC. But, when I tried to calibrate it for the max speed, the ESC burned up which means the motor drew more than 20A current. But, the problem is I am not getting high Current rated ESC in my region and some are taking more than a month to arrive. I thought of using a smaller motor but then I don't want to mess with the gearing of the RC car and don't want to spend much time on it. So, I would like to know if there is any way I can limit the current drawn by the motor with the ESC rated 20A so that it won't burn up the ESC. Any current limiting circuit or any other way I can do that??
