摘要

電動腳踏車是以無刷直流馬達驅動的腳踏車。本論文提出以數位訊號控制器dsPIC30F4011為核心設計電動腳踏車驅動控制器，以及了解馬達單向軸承構造跟馬達相位調整的功能，並搭配設計控制方法來驅動電動腳踏車的無刷直流馬達。馬達驅動方面使用矩形波120度驅動法產生矩形波電流之兩相電流導通式，並搭配六顆功率級晶體做馬達在運轉時開關切換的方式。
本論文以所設計的馬達驅動控制器並搭配線控訓練台來進行研究，觀察馬達轉速跟負載變化時的電壓、電流對馬達的影響，並改善其缺點，使其可以設計出良好的電動腳踏車之馬達驅動控制器。
電動腳踏車是新型個人的環保交通工具，也是綠色環保技術的核心產業。本作品完成驅動與控制的設計，軟體是使用C語言程式。由實驗結果可證實所設計的控制器穩定性。

An electric bicycle (e-bike) is a bicycle with a BLDC motor used to power the vehicle, or to assist with pedaling. In this thesis, the digital signal controller dsPIC30F4011 is designed to control and drive the e-bike. The one way clutch and phases modification are also studied in this thesis. There are three open loop control methods are proposed to drive the e-bike. Since the trapezoidal EMF is induced in the rotor, the six-step pulse PWM technique is applied for the switching of motor drive. There are six power MOSFETs to be served as switches.
The experimental setups are the designed motor drive, the e-bike and the bicycle magneto trainer. The loading conditions are observed and the voltages and currents are also recorded for all of conditions. The best design is chosen and the performance is improved in this thesis.
E-bike is the newest personal eco-vehicle. E-bike is also a core industry of green technology. The control and drive circuits are implemented in this work. The software is realized by C program. From the experimental results, the proposed controller is well-designed and stability is guaranteed.
