MOTOR

PURPOSE:To increase the effective magnetic flux and the output of motor by providing a magnetizing portion to the part not facing the salient pole of the negative pole. CONSTITUTION:A motor is composed of a rotor made up of a magnetic pole 1 of a ring-shaped permanent magnet and a yoke 2 and a salient pole 4 provided inside the pole 1 and equipped with a coil. At this moment, the pole 1 is oriented upward to right and downward to right so that the flux phib and phic may face the opposing surface 4a of the salient pole. Thus, when the pole is oriented, for instance, centripetally at theta=30 deg. relative to the horizontal line at the top and bottom portions, the output can be increased by 15-25% more than in the case where the flux is magnetized usually only in the direction of horizon at the salient pole 4.
