Abstract
A system and method of restarting a switched reluctance motor after a cycling of power provided to the motor is provided that includes receiving at the motor a power-off signal followed by a power-on signal, determining a rotational speed of a rotor, and energizing a stator only when the rotational speed of the rotor is determined to be less than a threshold speed.
