Challenges in Developing Hardware-In-Loop Model of Cage Induction Motor with Eccentricity Fault

Abstract

In this paper, an attempt is made to develop a MATLAB based Hardware-In-Loop compatible model of a three phase cage induction motor with a provision to accommodate eccentricity fault. The major benefits of the attempted work include compatibility with commercially available real-time simulators, facilitation of testing motor control units of electric vehicles when the motor is subjected to eccentricity fault, and ability to simulate in real-time varying severities of eccentricity fault. Modeling of the eccentricity fault is made by using the widely adopted modified winding function approach. Real-time simulation of the developed model is attempted by building a MATLAB model that utilizes pre-computed inductances for real-time execution. Finally, the major challenges encountered in this attempt are presented and discussed to pave way for further research. � 2018 IEEE.
