近年來，由於環保意識的抬頭，分數槽集中式繞組馬達(Fractional-Slot Concentrated-Winding, FSCW)逐漸受到重視，而提高馬達之效率與降低馬達運轉之溫度成為重要的研究方向。本文提出利用混合式繞組之永磁同步電機設計流程，並與傳統式Y接繞組進行比較，透過有限元素分析軟體(Finite Element Analysis, FEA)與樣機實作相互驗證。
由於分數槽集中式繞組之高階諧波磁動勢含量所導致轉子磁鐵渦流損失增加、反電動勢失真以及轉矩漣波增大等不良性能產生，本研究透過空間諧波原理之分析，並針對傳統式Y接繞組與混合式繞組之空間諧波進行比較，提高轉矩輸出之主要空間諧波含量，而磁鐵採用內藏式V型之結構，增加結構強健性並提升磁通集中因數。此外，本研究建立參數化模型，對馬達定轉子以及磁鐵之各項尺寸進行最佳化設計。

In recent years, Fractional-Slot Concentrated-Winding (FSCW) motor have gradually received attention due to its high torque/power density, high efficiency, and extended constant power speed range (CPSR) capability. For these reasons, researchers have been studying this type of motor to improve its performance as the machine suffers from the high magneto-motive force (MMF) harmonics content, which induces high rotor losses.
In order to improve the performance of the FSCW motor, this thesis proposes a Delta-Wye winding type configuration to reduce the MMF harmonics content produced by the traditional winding arrangements of the FSCW motors. In addition, the rotor adopts a V-shaped magnet arrangement to increase the robustness of the structure and improve the flux concentration factor.
In this thesis, analytical calculation is applied to describe the ideal effect of the Delta-Wye winding on the motor performance. Then, finite element analysis (FEA) simulation, and experiment are utilized to validate the effectiveness of the proposed winding configuration on the FSCW motor. The results showed that by eliminating the MMF harmonics, the core losses are reduced, and the rotor temperature is decreased significantly, consequently, improving the torque and efficiency of the machine.
