ABSTRACT:
The object of the present invention is to increase torque generation of a motor, to minimize a motor size, and to reduce a motor cost by improving a magnetic circuit of a rotor. In order to achieve the object and make effective use of the power of each permanent magnet within the entire motor, the present invention provides a motor comprising magnetic circuits for the pole N 5 commonly connected to the north pole of permanent magnets 7, magnetic circuits for the pole S 6 commonly connected to the south pole of permanent magnets 7. Also, the motor further comprises magnetic poles N in the shape of protruding poles of the north pole and the magnetic poles S in the shape of protruding poles of the south pole. The magnetic poles N, forming a part of the magnetic circuits for the pole N, are placed on a part around the perimeter of the rotor, and the number R of the magnetic poles N is different from the number m of stator poles. The magnetic poles S, forming a part of the magnetic circuit for the south pole, are placed on a part around the perimeter of the rotor alternately in a rotational direction of the rotor with the magnetic poles N in the shape of protruding poles of the north pole and the number of the magnetic poles S is R.
