This thesis presents a novel direct wheel motor drive for electric vehicles (EVs). The proposed motor is a permanent magnet square-wave motor whose rotor with rare earth magnets forms the exterior of the motor which can be fitted with a wheel tyre to realize the direct drive for each rear wheel of an EV. The interior stator with its windings is to be rigidly mounted onto the suspension and frame structure of the vehicle. In order to achieve the direct drive without any mechanical transmission for EVs, the wheel motor has been designed as a low-speed high-torque motor.
