電動載具之直流無刷馬達驅動系統設計

本論文主要在設計一運用於電動載具的經濟型無刷直流馬達驅動器，以實現無刷直流馬達的運轉控制。本系統包括控制單元及電機驅動模組兩大部分。驅動模組即以控制核心為ARM Contex-M0 STM32F030C8 微處理器之驅動器控制電路，加上霍爾感測元件和周邊介面電路; 控制單元即驅動器之控制程式，包含無刷直流馬達的控制理論及相關介面技術。透過軟體的設定，本文所提出之電動機驅動模組可搭配不同驅動方式，不需要更改電路設計。並且透過電流限制功能可控制電動機輸出轉矩，使電動載具可運轉於省電模式。實驗結果證實所設計的驅動器具有架構簡單、成本低廉及性能優越的特性。

In this thesis, a drive system of the electrical vehicle is designed and investigated. It is used to achieve power and speed control of a brushless DC motor. The system consists of a control unit and drive module which combines a drive circuit. The drive module comprises driver control circuit based on ARM Cortex-M0 microprocessor STM32F030C8 as control unit, hall sensors and peripheral interface electric circuit. The control unit program includes brushless DC motor control theory and interface technologies. By modifying the software of the system, the proposed drive system can be implemented in various driving methods without changing circuit design. By limiting the armature current, the vehicle can be operated under the power saving mode. Experimental results demonstrate that the designed driver is simple, lower cost and good performance.
