磁性齒輪相較於傳統機械式齒輪，擁有非接觸式傳動、過載保護、可靠性與使用壽命長等優點，基於磁性齒輪的應用優勢，磁性傳動近年來漸成為熱門之研究議題。本研究基於同心式磁性齒輪，本論文延伸至軸徑向式磁性齒輪，提出創新型之錐形軸徑向式磁性齒輪。此新型設計具有磁通路徑較短、體積較小與漏磁少等優點。在理論方面，利用等效磁路分析法，且討論各設計參數對最大靜態轉矩的關係，以此建立一套設計流程，並使用3D有限元素模擬軟體驗證磁性齒輪性能。在實作方面，本研究結合了金屬積層製造技術列印3D導磁結構，實現新型錐形軸徑向式磁性齒輪結構，減少製作成本與困難度。本文亦結合螺桿擠出膠磁列印機台與三維傘型導磁鐵芯結構，探討錐型磁鐵應用於磁性齒輪的問題，並以實測驗證模擬結果與金屬積層製造技術應用於磁性齒輪的可行性。

With increasing requirements for motors in recent years, the characteristics of low vibra-tion, low noise, maintenance free and overload protection in particular, the coaxial magnetic gear (CMG) has become an attractive potential alternative to the traditional mechanical gear box. However, due to its complicated structure and multiple air gaps, the conventional radial type CMG is difficult to be manufactured and assembled, and so its applications are restricted. The axial-radial magnetic gear (AGMG) could be a possible way to overcome such fabrica-tion problems by putting the steel pole pieces around the outside of the two rotors instead of between them. However, the longer the flux paths between the two rotors, the lower the torque and energy transmission.
To overcome this drawback while retaining the advantages of the AGMG, this thesis investigates a novel design of axial-radial bevel magnetic gear (ARBMG) that adopts bev-el-type magnet. The ARBMG design not only decreases flux leakage, but also shortens flux path. A prototype of the ARBMG design approach is created to verify the simulation re-sults as well as the feasibility of the proposed additive manufacturing approach.
