摘要
本文介绍一种在某些工程上常作的假设条件下，利用磁场分析法，直接解算永磁电机空载、负载气隙磁密波形，空载电势波形，磁通量以及电磁力矩的方法；并同非线性有限元分析的结果，以及实验结果进行了比较。其计算精度高，而计算量仅相当于一般的磁路法，并且容易在计算机上实现。
In this paper,an approach for calculating the air-gap magnetic density waveforms,the EMF waveforms,the flux and torque of permanent magnet machines is introduced. The derivations are based on two-dimensional field theory. This approach can easily be realized using a simple computer program and it takes a few computer time. The resultS obtained by the approach are verified by comparsion with the results obtained by finite-element-method and test.
