磁通切换永磁无刷电机以其高的转矩密度、简单坚固的转子结构以及永磁体和线圈都位于定子上的特点而成为一种有吸引力的电机类型。通过二维和三维有限元分析，比较了标准拓扑和三种模块化容错设计在输出扭矩、磁链、反电动势和电感方面的性能。结果表明，FSPM电机可以在不引起显著性能损失的情况下设计成容错电机，但为了保持正弦反电势波形和减小转矩脉动，可能需要一定程度的转子歪斜。报告了标准和容错FSPM机器拓扑的实验验证。
Flux-switching permanent magnet (FSPM) brushless machines have emerged as an attractive machine type by virtue of their high torque densities, simple and robust rotor structure and the fact that permanent magnets and coils are both located on the stator. Both 2D and 3D finite element analyses (FEA) are employed to compare the performance of a standard topology with three modular, fault-tolerant designs in terms of output torque, flux-linkage, back-EMF and inductances. It is shown that the FSPM machine can be designed to be fault-tolerant without incurring a significant performance penalty, but that some degree of rotor skewing may be required in order to maintain a sinusoidal back-EMF waveform and reduce the torque ripple. Experimental validation is reported for both standard and fault-tolerant FSPM machine topologies.
