摘要
对以磁通切换永磁(FSPM)电机为代表的定子永磁型电机固有轴电压机理进行了研究,建立了FSPM电机固有轴电压分析的2D和3D有限元模型,探讨了固有轴电压与电机结构参数之间的关系,对不同电机转速、转轴直径和材料、转子偏心度和电枢电流作用下固有轴电压的特性进行了仿真计算,最后以一台12/10极FSPM电机的实验结果验证了分析和仿真计算的正确性,为高速定子永磁电机的设计和可靠性分析奠定了基础。
The inherent shaft voltage mechanism of the stator permanent magnet （ Stator-PM ） machines re-presented by the flux-switching permanent magnet （ FSPM） machine is analyzed. Both the 2D and 3D finite ele-ment analysis models are developed and simulation is carried out for different speeds, shaft structures and materi-als, rotor eccentricities and armature currents. Finally, the experiment on 10-rotor-pole and 12-stator-slot FSPM machine verified the correctness of analysis and simulation. The results will be helpful to design and reliability a-nalysis of high speed permanent magnet machines.
