提出了一种基于ANSYS Maxwell 2D的永磁同步电机(PMSM)场路结合电磁设计方法。通过ANSYS Maxwell 2D软件分析计算得出PMSM 2D理想电机模型的空载励磁电动势、负载时的励磁电动势、直轴同步电抗和交轴同步电抗参数,并以此修正基于电路和磁路的电磁设计程序中用来计算空载励磁电动势、负载时的励磁电动势、直轴同步电抗和交轴同步电抗参数的校正系数,从而使得PMSM的设计结果更加准确。通过该方法设计了PMSM并进行了试验。试验结果验证了该设计方法的正确性。

A fieldcircuit combined electromagnetic design method for permanent magnet synchronous motor (PMSM) based on ANSYS Maxwell 2D software was presented. Through the analysis and calculation by ANSYS Maxwell 2D software, noload excitation electromotive force (EMF), excitation EMF under load, and daxis and qaxis synchronous reactance of ideal 2D model of PMSM were obtained. These parameters were used to correct the correction coefficients in the electromagnetic design program based on circuit method. The correction coefficients related to noload excitation EMF, excitation EMF under load, and daxis and qaxis synchronous reactance made the design results of PMSM more accurate. The correctness of this design method was verified by test results of a newly designed PMSM.
