Fault Diagnosis for Induction Motors Using Finite Element Method - A Review

Abstract

Condition monitoring and fault diagnosis of induction motors is one of the key concerns for reliable operation of critical industrial processes. The finite element method (FEM) offers a great insight of the fundamental principle and demonstrates physical operation of the machine more thoroughly than analytical approaches. It elaborates the machine's complex geometry and illustrates electromagnetic properties of induction motor precisely. It considers nonlinear effects of the machine, and determines the machine parameters such as the magnetic field distribution, flux linkage, electromagnetic torques, and flux density. In this paper, a literature review is conducted on finite element method under consideration of fault diagnosis techniques for induction motors.
