本論文旨在針對旋轉式感應耦合結構與可旋型非接觸式電能傳輸系統進行優化設計，並應用非接觸式感應電能傳輸技術，研製具高電能傳輸效率之新型旋轉式感應耦合結構。於本文電磁感應耦合結構設計之特點係以同軸形式交錯夾層之初、次級側線圈進行配置，以有效增強耦合結構之電磁感應能力，並將作為磁場導引用途之鐵芯配置於固定不動之初級側端，藉以減少次級側線圈於旋轉過程所需承受之應力。此外，本文建置一適用於感應供電驅動之旋轉機具以驗證本文所設計之旋轉式感應電能傳輸系統之可行性。經實驗測試，本文系統可確實以感應供電方式驅動旋轉機具運作，整體系統電能傳輸效率最高可達94.8%；於系統最大功率輸出1030W時，電能傳輸效率為88%。

The purpose of this thesis is aimed at analyzing and improving the coupling structure of contactless rotary transformer that has been put into the design of the existing industrial applications. The main feature of the proposed rotational transformer is that the windings are coaxial-interlayered to improve the magnetic coupling capability. Besides, there is no ferrite core used in secondary-side. This helps to ease the exerted force on spindle by the stress of secondary-side. Moreover, for the reason to verify the feasibility of the inductive power transfer system for rotary application, an inductive powered rotary machinery and the control system has been integrated. Finally, the experimental results show that the rotary machinery is able to be powered and work by the proposed system. The maximum power transfer efficiency has reached about 94.8%. In addition, the maximum output power received in load is 1030W with transmission efficiency 88%.
