摘　　要：研究了变频调速三相异步电动机的异常振动问题。介绍了电机的振动原理、主要噪声源的特性。针对某变频调速三相异步电动机运行过程中振动异常并有明显噪声的情况,依据电机振动噪声的原理,测量该电机的振动及噪声信号,通过时域、频域、包络检波等方法分析异常振动信号,找出异常振动的原因,并针对该问题提出了检修建议。The motor＇s exceptional vibration is researched. The vibration principle and mainly noise source of motor are presented. According to the situation of exceptional vibration with obvious noise during a motor operation, first we measure the motor vibration and noise signal, then we can analyze the collected signal according to time domain, frequency domain, envelope detection or other methods to identify the reasons for abnormal vibration. There certainly has some reference value for motor fault diagnosis
