由於稀土永久磁鐵的革命性發展，磁性齒輪得以有效提升性能，已漸縮小和機械式齒輪之扭矩密度差距，能與機械式齒輪互補應用。磁性齒輪在發展上，可整合於電機架構上做整體設計。本文針對近年來新興之諧波式磁性齒輪架構所衍生的「諧波式磁性齒輪電機」設計，提出一結合磁性齒輪之諧波調制原理以及電磁場諧波分析之設計流程，用以解決設計上參數耦合的問題。另外，本研究亦探討氣隙磁通密度的諧波對於該新型電機的影響，找出電機設計參數上和磁性齒輪參數上之相互關係，並利用電磁場套裝軟體Ansys Maxwell進行分析驗證後，設計出一小型化整合型磁性齒輪電機，並透過原型機的實作和量測驗證其性能，此設計深具未來小型化磁性齒輪電機之應用潛力

With the evolution of permanent magnetic materials, magnetic gear has improved in efficiency and load capacity. Moreover, the difference in performance between magnetic gears and mechanical gears is gradually diminishing, such that it is now possible to combine both kind of gears in a system for a better transmission. According to the concept of elec-tromagnetism, the PMs in the magnetic gears can be replaced by coils, and the magnetic gears will be a new type of motor with a gear ratio. Therefore, the main purpose of this the-sis is to find out a design procedure for the new kind of motor with a gear ratio. The pro-cedure presented in this thesis will integrate the theory of harmonic modulation in magnetic gears alongside the concept of electromagnetic field in motor design. With this established procedure, reduced time to solve parameter-coupling problems in the above mentioned concepts is achieved.
In addition, by analysing effects of the flux densities harmonics in the inner and outer air gaps, parameter relationship between designing a motor or a magnetic gear can be estab-lished. Finite Element Analysis (FEA) software, Ansys Maxwell, is used for analysis and design in this study. After the design procedure of the magnetic gear motor has been estab-lished, a miniaturized magnetic gear motor prototype is fabricated to verify the results of the FEA.
