In this paper, a new type of memory motors, namely the stator-permanent-magnet (S-PM) doubly salient flux memory (DSFM) motor is proposed. The concept of flux memory is due to the nature that the magnetization level of the AlNiCo permanent magnet (AlNiCo-PM) in the motor can be regulated by a temporary DC current pulse and be memorized automatically. To accurately analyze the DSFM motor, a piecewise-linear hysteresis model is employed in the time stepping finite element method. Both static and transient electromagnetic performances of the DSFM motor are successfully simulated. Finally, the validity and accuracy of the proposed method are verified by experimental results.
