摘要

本論文目的以實現電動機車之換檔的功能，由可變的供應電壓及馬達繞組串並聯，可組合四種檔位，並以FPGA控制完成自動換檔的功能，將電動機車行駛在馬達較高的效率之區域，提高電動機車行駛效率。
　　以本實驗室研發出的舊四代馬達及新四代馬達完成馬達的性能曲線，利用此性能曲線來估測兩馬達在四種檔次的加速性及最高速度，並以觀察的方式決定四種檔次的可行性，來決定換檔的時機點，將現有的殘電顯示、可變的輸入電壓及馬達繞組串並聯結構，完成整車的目的。
　　整車完成後，測試兩馬達應用在電動機車上的性能，如極速、加速性、爬坡力、續航力等，最後完成兩馬達的性能比較。

This research aims to integrate the propulsion system to test the performance of the direct-driven electric motorcycles. The propulsion system of the dedicated vehicle consists of a stack of batteries, motor controller and drive, axial-flux disk-type four-phase bushless dc motor, and the display of the state of capacity of batteries. The series and parallel connections of batteries and motor windings constitute various gears, drive-by-wire into realization in the light of the implementation on the field programmable gate array (FPGA) chip.

The integration of the novel propulsion system is tested on the 4th generation wheel motor; the old one has larger diameter, more turns on winding, larger torque, but lower speed than the new one. Fist, the shift points of gear are determined by investigation the efficiency and torque curves for various gears, in such a way that the driving smoothness and efficiency during the gear shifts are satisfactory. Second, the performance on acceleration, slope climbing, maximum speed, and driving range if tested on road, dynamometer and a motorcycle test platform. During the driving range test, the state of capacity, or residual capacity, is recorded and displayed by continually measuring and calculation ampere-hours and transient open-circuit voltage, coded in the FPGA chip.

The experimental results show that the new 4th generation wheel motor has batter performance than the old one. The driving range test under the same condition shows that the new 4th generation motor is superior over the old one and a commercial product. However, the dedicated propulsion system of the direct-driven motorcycle need further development and improvement, to fulfill stringent environmental laws as well as to satisfy consummers’ need.
