Adjusted electrical equivalent circuit model of induction motor with broken rotor bars

摘要

Detection of broken bar faults of the induction motor is important in electrical machine fault prediction. The proper model of the motor with a broken bar can be a useful tool for fault determination studies as well as a basic material for the development of inverse theory implementation possibilities in electrical machine diagnostics. In this paper the adjusted electrical equivalent circuit model is presented. Possible practical applications of the electrical equivalent circuit model are added. Moreover, possible failures that can affect on performance of electrical machines are classified.
