    Abstract: 由於12/8 磁阻馬達的凸極結構,使得馬達具有可以做徑向力控制的特性,但為了能同時產生轉矩與所需的徑向力,各極線圈必須可以獨立激磁。一般的SRM 會因為1)外加的偏心負載或2)轉子偏心,而使馬達產生不平衡的徑向立,導致震動的現象。為消除此一問題,本計畫以設計並製作一12/8 磁阻馬達,同時利用FEM 軟體分析徑向力變化的特性,根據馬達徑向力與力矩分析之結果,設計一弦波激磁的控制法則,經由此一法則激磁各極線圈可以產生所需的徑向力與輸出轉矩,並設計一套換相法則來降低換相所產生的震動。最後並建立實驗平台以震動的方式驗證以上理論分析的結果。
    Abstract-Due to its special structure the shaft radial force and torque of the three-phase 12/8 switched reluctance motors can be controlled independently by properly distribution of current at each pole of the excited phase. The radial force produced can be used to counterbalance: 1) external force acting on the motor shaft, or 2) the imbalanced force due to rotor eccentricity, so as to reduce vibrations of the motor. In this project, the radial force and torque produced by the SRM under sinusoidal excitations are analyzed, and a model for radial force is proposed. It was found that when excited with sinusoidal currents, the SRM can generate the desired shaft radial force in any direction in the rotational plane without interfering with the rotational torque. The results were verified with finite-element software. An experimental system was also built for verification of the proposed scheme.
