本研究因應節省能源及環境保護議題而生，因現行工業應用中大量使用感應電機做為動力來源，然而感應電機在能量轉換效率表現上，受其轉子銅損影響而有所降低，倘若能以轉子不會產生銅損的同步磁阻電機取而代之，免除轉子銅損的問題對整體能量效率而言必當有所改善。

同步磁阻電機具有結構簡單、高效率和低製造成本等優良特性。故以同步磁阻電機替換感應電機之可能性大幅提升。以目前已量產之IE3感應電機結構參數及定子繞線為基礎，使用本論文所提之設計法，設計功率介於0.75 kW到3.7 kW區間之同步磁阻電機並以其為參考，建立數學近似模型並探討及估算性能以驗證之。

The purpose of this research are to design the rotor structure of synchronous reluctance motor (SynRM) for energy conservation and environmental considerations, and to establish the approximate mathematical model of SynRM for evaluating the performance.

Since the induction motor is widely used in industrial application but its energy efficiency decreased by copper loss from rotor winding. We improve this issue by using SynRM because the rotor structure of SynRM consisting neither current conducting path nor permanent magnet. The copper losses in the rotor of SynRM are virtually eliminated that means the efficiency of SynRM is more efficient than induction motor.

The SynRM offers a potential substitute for upgrading induction motor because the characteristics of SynRM including simple structure, high efficiency and low cost of manufacture.
