永磁开关磁通电机结合了开关磁阻电机和永磁电机的优点。之前报道的所有三相PMSF电机在定子上有12极，每极嵌入一块磁铁，在转子上有10极。本文提出了一种新型结构的电机。它的转子上也有10个极，但定子上只有6个极。基本上，该结构在转矩密度、铜质量和绕组欧姆损耗方面都优于传统结构，并且通过适当的转子偏斜可以最大限度地减小齿槽转矩。此外，通过将传统电机和所提出的电机相结合，还提出了另一种新的结构
Permanent magnet switching flux (PMSF) motor combines the advantages of both SR motor and PM motor. All 3-phase PMSF motors reported previously have 12 poles on the stator where a magnet is embedded in each pole and 10 poles on the rotor. In this paper, a new structure motor is proposed. It has also 10 poles on the rotor, but only 6 poles on the stator. Basically, the proposed structure is superior to the conventional structure in the aspects of torque density, copper mass and winding ohmic loss, and its cogging torque can be minimized with proper rotor-skewing. Furthermore, by combining he conventional and proposed motors, another new configuration is also presented
