| 摘 要： | 轴向磁场磁通切换型永磁(AFFSPM)电机是一种轴向长度短、转矩密度高的新型永磁电机。该电机磁场呈三维分布,与径向磁场电机不同,需要对该电机进行三维有限元分析,从而增加了电机分析和优化时的计算时间和成本。基于等效磁路法分析了AFFSPM电机的静态特性,建立了AFFSPM电机的非线性等效磁路模型,采用该模型计算、分析了气隙磁密、空载永磁磁链、反电动势和电感等特性,并与采用三维有限元方法的计算结果进行比较,验证了AFFSPM电机等效磁路模型的准确性,表明等效磁路模型适用于AFFSPM电机初始设计和分析。

| Abstract: | Axial field fluxswitching permanent magnet (AFFSPM) machine was a novel machine with short axial length and high torque density. The 3D distributed magnetic flux of the AFFSPM machine required the 3D field analysis which increased the calculation time and cost of analysis and optimization. A nonlinear equivalent magnetic circuit model of the AFFSPM machine was built, and the static characteristics of the AFFSPM machine, including the airgap flux density, permanent magnetic flux linkage, back electromotive force and inductance characteristics were calculated and analyzed based on equivalent magnetic circuit model. The calculated results were compared with those predicted by 3D finite element method. The analysis results with two methods consist well, the feasibility of the proposed equivalent magnetic circuit model were verified. |
