变频调速三相异步电动机异常振动分析
Analysis of Exceptional Vibration for Three Phase Asynchronous Motor in Frequency Control
摘要
Abstract
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关键词
