開關式磁阻馬達為一種構造簡單、結構強健，具有高轉速高轉矩適合在惡劣環境下工作的馬達。當轉子扭轉時，其結構類似軸流式泵之抽水葉片，本文在此觀點下提出一磁阻馬達軸流式泵的構想及其設計方法，首先設計一傳統6/4極磁阻馬達，接著以同樣的角度扭轉定子及轉子，並分析不同轉子形狀及凸極齒寬的電感波型，並選取與原始磁阻馬達輸出轉矩比較下降最少者為最終設計，最後以實驗驗證磁阻馬達軸流泵之設計。

Switch reluctance motor is a simple structured and rugged motor; it has high torque and speed capabilities, and is suitable to operate in harsh environment. When the rotor of a SRM is skewed, its structure resembles the impeller of an axial flow pump. Based on this observation, a switch reluctance motor-pump is proposed and its design method is presented in this paper. A conventional 6/4 pole SRM is designed first. Then, the stator and rotor are skewed with the same angle. Inductance waveforms for various rotor shape and tooth thickness are analyzed. A final design is selected with the least reduction in torque capability comparing to the original SRM. Finally, experimental results have verified the feasibility of motor-pump design.
