隨著日漸嚴苛的電動機能源效率標準，永磁電動機受到的關注度也愈來愈高，該結構通過在轉子中安置永久磁鐵，能將電動機的能量密度與效率提升至更高的水平。然而根據其不同之應用導向，永磁電動機又可以分為短時間運轉與長時間運轉兩大類，在本研究中，將針對短時間運轉之穿戴式行動輔具以及長時間運轉之製冷壓縮機中的永磁電動機進行深入的探討。
在穿戴式行動輔具的應用中，本文將引入一維尼爾電動機，並透過其獨特之減速效應，設法提升輸出轉矩為市售電動機的兩倍，並搭配減半之減速齒輪齒比，進而降低其外部機械成本。同時通過有限元素法優化與硬體實測，證明其滿足該應用之性能需求並提供電動機設計者不同的選擇指南。
而在製冷壓縮機應用中，主要探討創新式V型永磁電動機、創新式V型同極永磁電動機與創新式表面型永磁電動機應用於其中之可行性。藉由理論分析模型與結構調整，改變其諧波組成以提升其平均轉矩與轉矩漣波表現，同時結合有限元素法與硬體實測證實其作為該應用替代方案之可行性。

With the stringent energy efficiency ratio (EER), the permanent-magnet (PM) motor gains more and more attention. Based on the different application-oriented, the PM motors can be divided into short-time operational motor, and continuous operational motor.
In the short-time operational application, the Vernier motor (VM) be proposed as the possible alternative of the exoskeleton system, because the advantage of high output torque. With the structural harmonic injection, the output torque can be doubled and halved the operational speed. Hence, the gear ratio and mechanical cost also can thus be decreased. Besides, by the finite element analysis (FEA) and hardware validation, the optimal VM not only can satisfy the application requirement but also provides a cost-effective selection to the manufacturer.
In the second topic, there are some possible alternatives to the refrigerant compressor application that were evaluated, include I-type permanent-magnet motor (IPM), V-type permanent-magnet motor (VPM), V-type consequent-pole permanent-magnet motor (CVPM), and surface-mounted permanent-magnet motor (SPM). Based on the theoretical analysis model, the output torque and torque ripple can thus be further improved by the structural adjustment. Besides, combining with FEA and hardware validation, those advanced structures were certified that are the possible alternative of refrigerant compressor application.
