軸流式開關磁阻馬達泵之無轉軸位置感測器控制

因為開關式磁阻馬達之轉子為凸極結構，若將轉子扭轉一角度則其形狀會與軸流式泵之葉片形狀極為接近，因此本文的目的即在探討此馬達與泵結合之構想的可行性。為了維持原開關式磁阻馬達的功能，定子與轉子極必需扭轉相同角度，此角度經計算以達到所需的流量，轉子形狀亦經特別設計以增加流體可通過的空間。又因流體需流經轉子，所以馬達轉軸不能有位置感測器，因此必須使用無位置感測器控制使馬達轉動。除了理論與模擬分析外，本文亦提供實驗結果以驗證馬達泵及控制系統的性能。

Due to its salient rotor structure, switched reluctance motor resembles axial flow pump when the rotor poles are skewed. The purpose of this research is to investigate the feasibility of such a switched reluctance motor-pump. In order to preserve the functions of a switched reluctance motor, both the stator and the rotor poles are skewed with the same angle, and the angle is determined from the desired flow-rate. Also, the shape of the rotor is redesigned in order for larger fluid flow. Since the fluid must pass through the rotor, the motor can not have any shaft position sensor. Therefore, a shaft position sensorless control strategy must be used for motor control. In addition to the theoretical and simulation analysis, experiments were also performed to verify the proposed motor-pump and the control strategy.
