Detection and discrimination of simultaneous stator inter-turn and broken rotor bar faults in induction motor

Abstract

Induction motor failures are mainly due to stator and rotor faults. In this paper, a novel method based on Park's vector approach for fault detection of induction motor is presented. Using suggested method it is possible to detect the various types of faults in squirrel induction motors. Further, paper focuses on the detection and discrimination of the simultaneous stator inter turn and broken rotor bar faults in induction motor. In order to evaluate the ability of the proposed method several experimental results are presented. The result demonstrates that the proposed method is effective and accurate and can be widely used in the induction motor fault detection.
