定子型永磁电机与定子型永磁电机相比，具有转子简单、绕组短端、磁体散热条件好等优点。本文首先介绍了三种类型开关磁阻电机的一般功率方程，然后推导了考虑特定拓扑结构的功率方程。基于这些功率方程，对不同类型的开关磁阻电机进行了理论比较。总共提出了八种拓扑并对其进行了基准测试。结果表明，在相同外径下，磁通开关永磁电机的功率密度高于磁通反转电机和双凸极电机。基于功率方程的比较为开关磁阻电机的优化奠定了基础。
The stator-mounted permanent-magnet (SMPM) machines have some advantages compared with its counterparts, such as simple rotor, short winding terminals, and good thermal dissipation conditions for magnets. In this paper, a general power equation for three types of SMPM machine is introduced first, and then, power equations considering the specific topologies are derived. Based on these power equations, theoretical comparisons are carried out between various types of the SMPM machines. In all, eight topologies have been presented and benchmarked. It reveals that the flux switching permanent-magnet (PM) machine owns higher power density than the flux reversal PM machine and the doubly salient PM machine under same outer diameter. The comparison based on the power equation has established a foundation for optimizing the SMPM machines.
