摘要

本文建立了具有匝间绕组故障的感应电机的简单动力学模型。采用有限元法对机床在故障状态下的参数进行识别。通过时间步进有限元分析验证了所提出的动力学模型。对于不同的故障绝缘电阻,动态模型结果与有限元分析预测的趋势一致。该模型适用于IM健康监测和轮间故障诊断。

Modeling of IM with stator winding inter-turn fault validated by FEM
In this paper a simple dynamic model for induction machines (IM) with inter-turn winding fault is established. Finite element method is used for parameter identification of the machine under fault condition. The proposed dynamic model is validated by time stepping finite element (FE) analysis. The dynamic model results exhibit the same trend as predicted by FE analysis for different fault insulation resistances. This model is well adapted for IM health monitoring and inter-turn fault diagnosis.
