Abstract :
A design technique for electric vehicles´ (EVs) induction motors using an optimization procedure is described. The supply inverter operates in PWM mode with the field oriented controller in both the constant torque and the constant power regions. The motor voltage regulation strategies are discussed in the first part of the paper, because the motor design is related to it. Thus, the nonlinear programming technique is applied in the design procedure. The proposed method has been applied to design a 17.5 kW induction motor with 30 kW peak power. Complete design results for motors with different characteristics (voltage regulation strategy, number of poles, base and maximum speeds) are also presented and discussed
