| Summary: | 碩士 === 國立交通大學 === 電機與控制工程系 === 88 === Due to the increasing need of environmental protection, electric vehicles have become an important target of vehicular technology development. Among the vehicle industry in Taiwan, the motorcycle owns the highest percentage of domestic manufactured parts. Meanwhile, the popularity of motorcycle has made itself a major pollution source in this country. Therefore, it is necessary to develop the electric motorcycle technology both from the industrial policy as well as the environmental viewpoint. The key technologies of an electric motorcycle encompass battery, motor, and controller. The controller, as the heart of the system,is responsible of driving the motor efficiently and controlling the motion. It consists of a control signal module and a power module. The purpose of this project is to design and implement the hardware of both modules based upon a digital signal processor. At the same time, flux weakening driving strategies are designed and experimented to access their improvement of torque and efficiency.
