Abstract

We have examined the optimum rotor design of an interior permanent magnet motor (IPM motor) for electric vehicles. By using double-layer magnets embedded into the rotor with the layers separated in the direction of the rotor radius, we have been able to construct a rotor that takes greatest advantage of reluctance torque, resulting in a 10 percent torque increase over the conventional IPM motor, which uses only a single-layer of magnets in the rotor
