感应电机转子断条故障诊断方法研究进展

Research Progress of Fault Diagnosis Methods for Rotor Bar of Induction Motor

转子发生断条故障后,电机的电流信号中将会出现故障特征频率分量。而基于定子电流信号分析的故障诊断方法可以做成非侵入式,结构简单,数据采集方便,因此是该方向研究的热点。总结了近年来基于定子电流信号分析的转子故障诊断方法,并对进一步的研究进行了展望。

When the bar of rotor is broken,some feature frequency components will emerge in the cur-rent.The fault diagnosis system based on analyzing the current signal is of interest in this area.This di-agnosis system may be designed as a non-invasion type into the induction machine,which is simple in hardware and easy to sample the signals.This paper surveys previous works on rotor broken-bar fault di-agnosis by current signal analysis and concludes with a range of further issues that must be solved.
