DETECTION OF INTERTURN FAULT IN THREE PHASE SQUIRREL CAGE INDUCTION MOTOR USING MAGNET

Abstract

In Industry the predictive maintenance has become a strategic concept. Economic interest of on line diagnosis of faults in electric machines gave rise to various researches in that field. This paper presents the fault detection of three phase squirrel cage induction motor using finite element model of the machine. Accurate models of the machine under healthy and faulty conditions are developed using finite element method and the performance of the motor is examined.
In this paper, the static two-dimensional analysis is done for stator inter turn fault. The machine parameters like flux linkage, flux density, stored magnetic energy are obtained for healthy and faulty motor. The results examined under various conditions are compared and the observations are presented.
