基于Ansoft汽车永磁电机磁场有限元分析

针对Ansoft Maxwell软件的电磁仿真方法是否有效,分别采用Ansoft Maxwell和Simplorer软件对磁场和电路进行仿真的方法。分析了永磁同步电机的结构,建立永磁同步电机的电-磁场理论模型和电磁损耗模型,用电磁仿真软件进行仿真。通过电机性能实验台测试永磁同步电机的关键输出特性,并与仿真结果进行对比分析。结果表明,参数误差均＜5%,验证了电磁仿真的有效性。

Finite Element Analysis of EM Field of Vehicle Drive Motor Based on Ansoft

Simplorer and Ansoft Maxwell are used to perform simulation analysis of circuit and magnetic field to show whether the Ansoft Maxwell electromagnetic simulation method is effective.The structure of permanent magnet synchronous motor is studied and the permanent magnet synchronous motor electric-magnetic field theory model and electromagnetic loss model established based on electric and magnetic field coupling theory.The simulation results are consistent with test results with an error less than 5% for all parameters.The above results prove that the electromagnetic simulation model and simulation method are effective.
