Dear all
I have been working on a project related to BLDC Motor. I am using a micro-controller, a three half bridge inverts and a BLDC motor.
I have finished the code of generating pwm signals feeding into the bridge inverter. The problem is that, I powered up the bridge circuit with +20V, the motor can not start itself. I had to flip my finger onto the rotor, kind of like giving an starting inertia, to make it rotating either CW or CCW.
I am really stuck on this problem and would anybody suggest me something that causes this problem?
Thanks,
Kim
