隨著環保與節能意識提高，電動機(馬達)佔電氣負載大部分的用電，因此研發高效能馬達便成為了節能首選。磁阻馬達有著結構簡單、生產成本低及高效率等優勢，其純矽鋼片的轉子結構，讓它能夠應用於高溫場所。
同步磁阻馬達雖有諸多優勢，但也避免不了其振動及噪音大與轉子慣量小的缺點，因此本論文將使用有限元素軟體ANSYS Maxwell，針對18.5 kW同步磁阻馬達做一系列的分析與研究，最初以選型分析得出應用層面較廣的折角型磁障層，再透過靈敏度分析找出影響轉矩漣波與功率因數較大的轉子結構，並定義出結構的分析順序。
後續利用一次一因子試誤法、田口法與相關演算法，優化其轉子結構，其中包括磁障層寬度、角度、形狀、橋部、肋部、積厚、氣隙、轉子斜列、材料等九種參數，並以最大化其功率因數與最小化其轉矩漣波為設計目標，使其輸出特性與穩定性能夠達到改善。
最後代入磁鐵輔助的設計，透過在轉子中加入低成本的磁石，讓同步磁阻馬達也能夠在性能上可以有更大的提升。所設計出的兩款馬達能根據應用場合選用合適的機型。

With the improvement of environmental protection and energy saving awareness, electric motors (motors) account for most of the electricity consumption of electrical loads, so the development of high-efficiency motors has become the first choice for energy saving. The reluctance motor has the advantages of simple structure, low production cost and high efficiency. The rotor structure of its pure silicon steel sheet allows it to be used in high temperature places.
Although the synchronous reluctance motor has many advantages, it cannot avoid the disadvantages of large vibration and noise and small rotor inertia. Therefore, this paper will use the finite element software ANSYS Maxwell to do a series of analysis and research on the 18.5 kW synchronous reluctance motor. At first, the angle-shaped magnetic barrier layer with a wide application level was obtained through the selection analysis, and then through the sensitivity analysis, the rotor structure that affected the torque ripple and the power factor was found, and the analysis sequence of the structure was defined.
Subsequently, the rotor structure is optimized using the one-factor trial-and-error method, Taguchi method and related algorithms, including the width, angle, shape, bridge, rib, thickness, air gap, rotor skew, material, etc. of the magnetic barrier layer. Nine parameters, and the design goal is to maximize its power factor and minimize its torque ripple, so that its output characteristics and stability can be improved.
Finally, the magnet-assisted design is introduced. By adding low-cost magnets to the rotor, the performance of the synchronous reluctance motor can also be greatly improved. The two designed motors can choose the appropriate model according to the application.
