基于阶比分析的永磁同步电机偏心故障诊断研究
Eccentric Fault of Diagnosis of Permanent Magnet Synchronous Motor Based on Order Analysis
摘要
Abstract
In this paper,based on the background of motor eccentric fault diagnosis,the fault characteristic of the traditional motor current analysis method is weak,and it cannot deal with the non-stationary signal,hence order analysis technology is studied and is used to transform time domain non-stationary signal into angular domain stationary signal.In this paper,the eccentric fault model of motor is established.The influence of eccentric fault on motor current is analyzed.The fault characteristics in order spectrum are obtained or realize the eccentric fault diagnosis.Simulation and experimental results show that this method can detect the eccentric fault of motor during non-stationary operation process,and effectively overcome the"frequency ambiguity"phenomenon caused by traditional fast Fourier transform.关键词
