摘　　要：电机的可靠性一直是相关领域的重点研究内容,而PWM控制技术的负面效应进一步增加了电机可靠性分析的复杂性和难度.目前,对PWM脉冲导致电机失效的机理和影响尚无系统的总结和分析.由于绕组绝缘和轴承是电机中失效率最高的两个部件,首先简述了PWM脉冲作用下绕组绝缘和轴承的失效机理,介绍了绕组绝缘和轴承可靠性研究中较为典型的试验和成果,总结和归纳了整体电机寿命预测技术的研究现状,最后讨论了电机可靠性研究中尚未解决的问题和今后可能的研究方向.The reliability of the motor has been the focus of research in related fields. The negative effects of PWM control technology further increases the complexity and difficulty of the motor reliability analysis. Currently there are no systematic analyses on the influences and failure mechanism caused by PWM pulses. Winding insulation and bearing are two vulnerable parts in motor. In the paper, firstly the failure mechanism caused by PWM pulses is expounded, and some typical results are introduced in winding insulation and bearing reliability, and the research status of the overall motor life prediction techniques is summarized. Finally, the unresolved problems is dicussed, and the possible domains in future are also analyzed.
