通过有限元分析和实验研究了制造公差对具有不同定/转子极数的三相和五相磁通切换永磁电机齿槽转矩波形和反电势波形的影响。在原型FSPM机齿槽转矩过大的原因已经确定。这是由于模块化定子结构，使其机械薄弱，导致C芯侵入气隙和不均匀的内定子孔。文中的分析对一般模块化永磁电机的设计和分析是有用的。
The influence of manufacturing tolerances on the cogging torque waveforms, as well as the back-EMF waveforms, in 3- and 5-phase flux-switching permanent magnet (FSPM) machines having different numbers of stator/rotor poles is investigated by finite element analyses and experiments. The cause of excessive cogging torque in the prototype FSPM machines has been identified. It is due to modular stator structure which makes it mechanically weak, leading to the intrusion of C-core into the airgap and an uneven inner stator bore. The analyses presented in the paper should be useful to the design and analysis of modular PM machines in general.
