摘　　要：利用互功率谱方法对异步电动机发生多根导条断裂故障进行了模拟仿真,包括连续断条和间歇断条故障。数字仿真结果表明该方法能在信噪比较低的情况下,有效地诊断转子断条故障。In this paper,the method of cross power spectrum is used to simulate rotor bars breaking faults of induction motor,including continuous breaking and intermittent breaking of rotor bars.Results of numerical simulation show that it can diagnose the rotor bar breaking faults effectively in the conditions of low signal to noise ratio,so the approach has a good prospect in project appliance.

关 键 词：异步电动机 故障诊断 互功率谱 间歇断条 连续断条
