Abstract:	本研究設計並製作一款微型軸向磁通永磁馬達，以PCB波浪式繞組構成定子，搭配環形永磁體轉子，並結合鋁合金轉軸與光固化樹脂外殼形成整體結構。研究重點在於外殼結構之優化設計，特別針對軸承配置與磁鐵固定方式進行改良，以確保高速旋轉下的機械強度與穩定性。最終完成直徑約30 mm、高度約25 mm之馬達原型，並搭配2吋雙葉螺旋槳進行靜態升力量測。實驗結果顯示，在鋰電池供電下，馬達可達約33,000 rpm之轉速，產生最高約23 g之靜態升力。綜合結果證實，所設計之PCB軸向磁通馬達具備應用於微型無人機推進系統的可行性與潛力。;This study presents the design and fabrication of a miniature axial-flux permanent magnet motor utilizing PCB-based wave windings as the stator and a ring-shaped permanent magnet rotor. The structure integrates an aluminum alloy shaft with a photopolymer resin housing to form a compact assembly. The research focuses on optimizing the housing structure, particularly the bearing arrangement and magnet fixation, to ensure sufficient mechanical strength and stability under high-speed rotation. The final prototype, with a diameter of approximately 30 mm and a height of 25 mm, was tested with a 2-inch two-blade propeller for static thrust measurement. Experimental results show that under a lithium-ion battery supply, the motor achieved a rotational speed of about 33,000 rpm and produced a maximum static thrust of 23 g. Overall, the results verify the feasibility and potential of the proposed PCB axial-flux motor for application in micro-UAV propulsion systems.
