Abstract
Energy conservation and environmental protection are growing concerns in recent years, which have encouraged the development of various electric vehicles (EVs) or hybrid electric vehicles (HEVs). Many types of EVs have been developed and practically operated but not been comparable with gasoline-powered vehicles. Therefore, it is imperative to develop more efficient and reliable propulsion system for EVs and HEVs. The axial-flux sandwich-type dc brushless motor, featuring compactness, low weight, and high efficiency, have become an alternative for the propulsion system of EVs. This wheel motor is optimally designed to achieve a maximum torque and power output at 28 kg-m and 4.67 kW, respectively, and the efficiency over 90% at rated speed. In order to promote this dedicated motor to its excellence, the electric drive with IGBT inverters is designed and manufactured. In addition, the electronic gearshift and field weakening method are employed to increase the constant power and speed ranges. The contribution of this thesis encompasses the optimal design and fabrication of two wheel motors, their drives, electronic gearshift and an extension of driving pattern. These two wheel motors have been installed on an experimental vehicle, and are going to be implemented on a solar-fuel cell-powered hybrid electric vehicle.
