摘　　要：分析了大型电动机内部故障及其外在表现之间的对应关系,主要讨论了引起电气信号、机械信号、温度信号等电动机参数变化的故障类型,介绍了一些电动机内部故障检测的最新成果,为电动机内部故障检测方法及保护方案的选择提供了参考依据。This paper analyzes the relations between the interior faults of large induction motors and their exterior appearances. It mainly discusses the fault types that arouses the variations of induction motors parameters, including electrical signal, mechanical signal, temperature signal, etc. Some new improvements for detecting the interior faults of induction motors are introduced, which can be used as references for the selection of the detection methods and protection schemes for the interior faults of induction motors.
