Abstract

In this paper, the dynamic characteristics of induction motor (IM) for electric vehicle (EV) are investigated by considering slot shapes of rotor. The rotor of NEMA class A is selected to optimize the slot shape by RSM. The initial slot shape of rotor slot model is designed by electromagnetic loading distribution method (LDM). Next, the shape of rotor slot is optimized by the response surface method (RSM). The dynamic characteristics of the optimized model for IM are compared with those of the initial model by finite element analysis (FEA). The efficiency of the optimized model shows good performance through whole-speed range.
