So far, two methods have been proposed to solve this disadvantage. The first method, proposedby Perov [2], is to enclose a permanent magnet rotor with a high hysteresis material as shown in Fig. Ua). The permanent magnet in this motor operates as a rotor of synchronous motor and the torque produced by it is added to the hysteresis torque. The output power per unit weight per unit loss of this type of motor is 2.5 to 6.0 (W/W .kg) which i much larger than that s of the conventional hysteresis motor (1.5 to 1.8 W / W *kg) and is comparable with that of an ordinary induction motor (2.3 to 3.0 W/W*k@ [ 2 ] . In the second method, proposed by Papst [ 3 ] , split bow-shaped high hysteresis pieces are used for the rotor as shown in Fig. Ub). Papst stated that the ratio o the width of the split ring to the f pole pitch of the stator should be a rational nunber. * noise. Special attention must also be paid
