摘　　要：采用有限元方法对笼型异步电机转子断条的故障特征进行研究。首先建立笼型异步电机物理模型,分别计算电机在健康状态和断条故障状态下的电磁场、转子各导条电流和定子电流,最后将计算结果与实验数据进行比较和分析。Fault features of broken bar in a squirrel-cage asynchronous motor are studied by finite element method （FEM）. The physical model of a squirrel-cage asynchronous motor is presented. Then the electromagnetic field, rotor currents and stator currents of the prototype under healthy condition and broken-bar condition are calculated respectively. Finally, some useful conclusions are obtained by comparing and analyzing the calculating results with those gained from experiments.
