Dual-mode operations of new stator-permanent-magnet double salient flux memory motor drive

The concept of flux memory is due to the nature that the magnetization level of the AlNiCo permanent magnet in the motor can be easily regulated by a DC current pulse and memorized automatically. In this paper, a new stator-permanent-magnet doubly salient flux memory motor drive is proposed. By regulating the magnetization level of the permanent magnets, the new motor can operate at double modes, the doubly salient permanent-magnet mode and the switch reluctance mode. Theoretic analysis, simulation and experimental results all confirm the validity of the proposed dual-mode operations of the motor.
