Incipient short circuit fault impact on service continuity of an electric vehicle propelled by dual induction motors structure

Abstract

The short circuit is among one of the most dangerous electrical faults in induction motor, which leads to serious implications on the motor operation and its performances. The present paper deals with the influence of the stator short circuit fault in its early stage in terms of performances and service continuity of an electric vehicle (EV) using dual induction motor’s structure piloted by Backstepping control. An equivalent induction motor model with turn-to-turn fault on one stator phase, without already assuming the temperature effect through an intrinsic model, is investigated and thereafter its impacts on electric vehicle performance using simulation tests are presented and discussed.
