摘要

本文论述了对转子故障感应电机二维有限元模型的验证。将有限元分析的输出结果与异步电机的实际实验室测量结果进行了比较。外部磁杂散场被用作基本诊断方法。要分析的主要参数是线圈上产生的感应电压，线圈感应电机轴径向的外部杂散磁场。快速傅立叶变换用于根据常用诊断程序评估电压频谱的各个分量。异步电机的二维有限元模型具有与实验室中真实电机相同的参数，包括额定输出功率、转速、功率因数、电压和电流。通过钻孔调整转子杆或在偏心情况下通过轴承中的错位设置造成不可逆的机器故障。

FEM Models of Rotor Failures in Comparison to Real Measurement of IM by External Stray Field

The paper deals with the validation of the 2D FEM model of induction motor with rotor failures. Output results of FEM analysis are compared to the real laboratory measurement of asynchronous motor. External magnetic stray field is used like the basic diagnostic method of it. The main parameter to be analyzed is the induced voltage generated on the coil, which senses the external stray field in radial direction of motor axis. Fast Fourier Transformation is used to evaluate the individual components of the voltage spectrum according to common diagnostic procedures. 2D FEM model of asynchronous motor has the same parameters of real motor in laboratory including nominal output power, rpm, power factor, voltage and current. Irreversible machine failures are created with adjustment of rotor bar by drilling or in case of eccentricity by misaligned setting in bearings.
