摘　　要：为探讨混合励磁磁通切换电机(flux-switching hybrid excitation machines,FSHM)的快速设计方法,以简单磁路法为蓝本,结合了磁网络法中关键磁路细分和迭代求解计算铁心磁导率技术,建立了某相电枢绕组磁链最大位置的单元电机非线性磁路解析模型。据此给出了电励磁绕组安匝数以及磁桥初始磁密的设置推荐值,并采用组合性试探法,对比分析了定子轭高对永磁体尺寸与调磁系数的影响规律;设计了一台1.5 kW、12/10极结构FSHM样机,进行了实验研究。有限元计算与实验结果验证了设计方法的正确性和有效性,为FSHM电机永磁与电励磁配置以及调磁系数等参数的确定提供了参考。In order to provide an analytical technique for the flux-switching hybrid excitation machine（FSHM） design,a nonlinear magnetic circuit method（NMCM） of maximum phase flux-linkage position was proposed.With equivalent magnetic circuit model as original version,NMCM adopts the subdivision technology of magnetic circuit and iterative solutions methods,taking magnetic saturation into account.The ampere-turns of electric excitation,the recommended value of initial magnetic bridge flux density,and the influence of stator yoke thickness on magnet dimensions and field regulating coefficient were also investigated.A 1.5 kW 12 /10 pole prototype FSHM was designed and the experiment was done.The finite element analysis and the experimental results demonstrate the correctness and effectiveness of the proposed design method.It provides reference for the assignment for electric excitation and permanent magnet excitation,and the field regulating coefficient.
