Analysis of Faulty Induction Motors Using Finite Element Method

Bashir Mahdi Ebrahimi Ph.D.

University of Tehran

5.1 Introduction

The basis of any reliable fault diagnosis method of electrical machines is precise performance analysis of them at different conditions. Modeling of faulty machines is the first step of this procedure and has considerable effects on the accuracy of results. The features that are utilized for fault detection are extracted from processing of signals that are simulated at this stage. The modeling approaches that ignore effective characteristics of the machines cannot be used for modeling faulty machines. The two-dimensional (2-D) and three-dimensional (3-D) finite element method (FEM) as powerful simulators have ...
