摘　　要：介绍了三相异步电机的一个新模型,该模型由原始的相轴线模型变换得到。运用该模型对定子绕组短路故障进行了仿真研究,通过对定子起动电流的频谱分析发现,定子绕组短路时,三次、五次、七次谐波增加较多。A new model of three phase asynchronous machine is presented. The new model was obtained by transforming the original phase axes model of three phase asynchronous machine. The model was used to simulate stator winding short-circuit. Analysis of the frequency chart of the stator start current showed that the third, fifth and seventh harmonic increased greatly.
