Abstract:
Provided is a method of operating a motor at a low speed. The method includes sensing an event corresponding to an angular position of the motor. If the event occurs between a first time threshold and a second time threshold, the method includes slowing the motor. If the event has not occurred by the first time threshold, the method includes increasing driving power to the motor.
