This paper proposes a hybrid permanent-magnet memory motor. Using finite element method, the utility of AlNiCo and ferrite as low-coercive-force (LCF) magnets in the motor is comparatively analyzed. The results demonstrate that the positive magnetization of the ferrite magnets is difficult, while the field-variation range with the AlNiCo magnets is not sufficient, and the motor-power density and the...
