Abstract: A two-stage braking method for a brushless DC (BLDC) motor. The method includes control a switching array to drive the BLDC motor according to a commutation scheme to decrease a speed of the BLDC motor, allow the BLDC motor to coast, determine the speed of the BLDC motor, and actuate high side switches and/or low side switches to substantially stop rotational movement of the BLDC motor.
