摘要
介绍了电磁场有限元分析软件JMAG的基本原理和功能特点。基于JMAG软件强大的耦合分析功能和二维瞬态场分析功能,对开关磁阻电机进行基于二维瞬态场的直接场路耦合时步有限元分析。该方法考虑电动机磁场饱和以及若干相同时激励时相间互感所带来的影响,提高了仿真精度。通过仿真和实验的对比,证明了该方法的正确性。
The basic principle and function characteristics of JMAG software of finite-element analysis in electromagnetic fields are introduced in this paper. Based on the powerful function of 2D transient analysis and coupled analysis of JMAG, a direct field-circuit coupled time-stepping finite-element model combined with 2D transient analysis is presented to analysis the switched reluctance motors. Magnetic saturation of the motor and the effects of mutual coupling between motor phases could be considered in this method. The comparison and analysis of the numerical and measured results indicates the validity of the method proposed in this paper.
