Characteristic Analysis of Induction Motor with Eccentricity and Broken Rotor bar by Finite Element Method and Motor Current Signal Analysis

摘要

This paper deals with fault characteristic analysis of squirrel cage induction motor by Finite Element Method (FEM) and motor current signal analysis (MCSA). Various fault cases of the induction motor are considered, and characteristic analysis of each case is performed by FEM. Based on the FEM results, the motor current signal is analyzed and compared to detect the condition of the induction motor. In addition, the torque and speed characteristic are also dealt with, and they are validated by experimental results.
