摘要

本文以大功率(1mw)鼠笼式异步电动机为研究对象，在时域上逐步建立有限元模型，对定子绕组短路、静偏心和转子断条等故障进行检测和演化。分析了这些故障在电机附近线圈传感器电压中的特征，为故障外观和故障演变的无创检测提供了解决方案。为了建立电机健康状态监测的最佳方案，研究了一圈传感器电压的有效值和两圈传感器串联差分连接的电压的最重要谐波的幅值。

Finite Element Analysis of the Noninvasive Detection and Evolution of Faults in a High Power Induction Motor through Neighboring Coil Sensors

Having as subject of investigation a high power (1 MW) squirrel cage induction motor this paper deals with finite element models step by step in time domain for the detection and evolution of the faults short-circuit in the stator winding, static eccentricity and rotor broken bar. The signatures of these faults in the voltages of coil sensors placed in the motor neighboring are analyzed in order to offer solutions for the noninvasive detection of the fault appearance and of the evolution of faults. The rms values and the amplitudes of the most important harmonics of the voltages of one coil sensor, respectively of two coil sensors series differential connected are investigated in order to establish the best solution for the monitoring of the motor healthy state.
