本文旨在於研製一高性能直流無刷馬達驅動系統，以提升電動機車運轉的性能與效率。對直流無刷馬達高速轉矩補償、弱磁控制與再生煞車能源回收技術加以研究分析及設計製作，以期有效提升電動機車極速、續航力。
架構中，以微處理器晶片8XC196MH為核心，配合周邊驅動電路及適切的人機介面軟體，結合成一完整軟硬體系統。另外，並以PIC16F877單晶片設計PC-Based 馬達轉矩-轉速特性量測系統，來分析馬達驅動器運轉特性。利用此馬達轉矩-轉速測試平台，以驗證所推導理論的正確性與可行性。

A new designed high performance Brushless DC Motor driving system is proposed. This system involves the analysis and implementation of the high speed torque compensation, flux-weakening control and regenerative braking energy recovery techniques that would enhance the maximum velocity and increase the drive range of the electric motorcycle.
In this thesis, a hardware scheme consists of 8XC196MH microprocessor, suitable peripheral circuits, and the proper man-machine interface software are established for experimentation. In addition, in order to realize the operational performance of the motor driver, a PC-Based torque-speed characteristics measurement system by using PIC16F877 microprocessor is established. The torque-speed test bench for motor proves that the proposed system can be fulfilled the requirement.
