Abstract: A non-rare-earth flux mnemonic doubly salient permanent magnet motor（FM-DSPM） was presented, which used the magnetizing windings to adjust flux and operating point of permanent magnets（PMs） on-line. Thus, high reliability and fault-tolerant ability can be achieved. In order to solve the normal open-circuit fault, the magnetic reconstruction of windings was proposed. That is, the field magnetic motive force and armature reaction magnetic motive force of the motor were changed to complete the fault-tolerant operation under the situation of single-phase circuit faults. For the two methods, the magnetic reconstruction of single winding and the remedial brushless DC（BLDC） operation were analyzed and compared by MATLAB. Both of them can achieve similar torque output and fault-tolerant abilities. Finally, the experiment results prove that the proposed control strategy is correct and reliable.
