A three-phase reluctance motor with a large output torque used to drive various pieces of industrial equipment, wherein two adjacent magnetic poles (16a and 16a') and two magnetic poles (16d and 16d') faced to the above magnetic poles in the direction of the motor diameter are provided for each of the first through third phases, the four magnetic poles are excited by four exciting coils (17a, 17a', 17d, and 17d'), and all exciting coils of each phase generate a large magnetomotive force. Thus, the limited magnetic coil arrangement space in the motor is effectively used, the magnetomotive force of the exciting coils is increased, and a large output torque is generated. Moreover, when the exciting coils (17a, 17a', 17d, and 17d') are not energized, the magnetic energy stored in the exciting coils comes into the exciting coils (17b, 17b', 17e, and 17e') of another phase and immediately decreases, and the exciting current in the exciting coils of another phase immediately rises to allow the motor to operate at a high speed. <IMAGE> |
