摘要
磁通切换型双凸极永磁同步电机具有结构简单、输出转矩大、转矩密度高以及磁链、反电势正弦等优点,能够有效拓宽电机调速范围,适用于新型混合动力汽车和新能源发电等领域。在深入分析磁通切换型永磁同步电机磁通切换工作原理基础上,采用有限元设计了一台12槽/10极磁通切换型双凸极电机,计算了其电动状态下气隙磁场、永磁磁链和反电动势等静态特性,研究了其不平衡磁拉力。在此基础上,对所设计电机转矩性能进行了分析和优化,定量研究了影响其齿槽转矩的主要因素。最后通过一台2 k W样机对其转矩特性进行了实验验证,实验结果与Ansoft有限元仿真结果一致,验证了上述方法的正确性。
With the features of simple structure,large output torque,high torque density and sinusoidal magnet flux linkage and back EMF,flux switch double salient permanent magnet synchronous machine（ FSPMSM） can effectively broaden the performance speed range in the fields of hybrid vehicles and novel energy generation applications. Based on the analysis of the working principle of this machine,one 12 slots /10 poles FSPMSM was designed by FEM,in additional,the corresponding air-gap flux density,the flux linkage,the back EMFs and unbalanced magnet pull of the machine were calculated. The finite element method was used to optimize the torque performance of the machine,and the cogging torque was studied and calculated quantitatively in terms of several major parameters. Finally,one 2 k W prototype was designed to investigate the above analysis and calculation. The experimental results are consistent with the Ansoft FEM results,which verify the correctness of above methods.
