ABSTRACT:
A switched reluctance motor having a rotor and a stator is provided the motor includes means for adjusting a relative angle between a switch turn-off angle at which a switch for supplying power to a coil is turned off, and a tooth overlap angle at which a tooth portion of the rotor and a tooth portion S of the stator are overlapped according to a predetermined calculation. The switched reluctance motor has reduced vibration and noise levels, thereby increasing their application.
