摘要:

在利用ANSYS-Maxwell 2D 对电机气隙磁密进行傅里叶分析的基础之上,设计了一款基于Python 语言的计算程序。对ANSYS 有限元仿真计算软件所生成的大量数据,该程序给出清晰直观的傅里叶分解下谐波的次数以及各个次数所对应的磁密幅值。以一台48 槽8 极的PMSM 为例,用有限元分析的方法对其径向磁密分析仿真,再利用设计程序对仿真结果进行后处理,验证了程序的正确性、可靠性和直观性。最后,进一步分析了极弧系数对于径向磁密的谐波畸变率影响。

Abstract:

Based on the Fourier analysis of air gap flux density of the motor with ANSYS-Maxwell 2D, a program based on Python was designed. The program given clear and intuitive harmonic number and the amplitude corresponding to a large number of data of magnetic density on Fourier decomposition generated by ANSYS finite element method simulation software. By finite element method, the radial flux density of the PMSM with 48 slots and 8 poles was analyzed,and processed by the design program, verified the correctness, reliability and intuitive of the program. The influences of the embraces on the harmonic distribution of the radial magnetic density was analyzed.

Key words: permanent magnet synchronous motor (PMSM), radial magnetic-field, total harmonic distribution, Python
