A design technique for EV (electric vehicle) induction motors using an optimisation procedure is described. The supply inverter operates in PWM mode (pulse width modulation) with a field oriented controller in both constant torque and the constant power region. The motor voltage regulation strategies are discussed in the first part of the paper, because the motor design and the invert kVA size are related to it. Thus, the nonlinear programming technique is applied for the three-phase induction motor designs in the design procedure. The proposed method has been applied to design a 17.5 kW induction motor with 39 kW maximum power. Complete design results for motor with different characteristics (voltage regulation, pole number, base and maximum speeds) are presented and discussed.
