| Summary: | 碩士 === 元智大學 === 機械工程學系 === 98 === The major of this thesis, is to survey the utility of the serial type of hybrid oil/electric motorcycle, also research on the D.C. (Direct Current) brushless motor generator and the 50 c.c two cycle motorcycles engine. Furthermore, the electric power transformed by engine at both fixed speed and fixed fuel situation were analyzed. To meet the target of power saving. The study of the electric power consumed by electric bike at fix speed was conducted to understand the relation between electric supply and consumption.
The results show that current consumption becomes low when the electric bicycle runs at low speed; on the contrary, current consumption is high when the electric bicycle runs at high speed. The endurance when running at low speed is better than running at high speed is caused by the capacity of battery and additive current. Comparing the efficiency with D.C. brushless motor, electric generator of car, and 50c.c. two cycle motorcycles, the D.C. brushless motor is better than car''s electric generator, also fuel-efficiency of D.C. Brushless motor is better too.
