交流电机转子断条故障程度诊断方法的研究

Diagnosis of Rotor Bar Breaking Fault of AC Motor

转子断条故障程度检测包括转子断条数目检测和断条时间的检测。M ATLAB仿真证明,对重构后的特征能量系数做快速傅里叶变换可以得到特征频率值和故障特征量的幅值,由此可推断出转子断条故障程度的相关信息,为故障程度判断提供依据。

In the diagnosis of rotor bar breaking faults, we should detect the number of the broken bars and the time of the bar breaking. Some experiments based on MATLAB show that we can judge the severity of a rotor bar breaking fault by the characteristic frequency values and the magnitude of fault characteristic value which come from the FFT of the reconstrueted characteristic energy coefficient.
