本研究致力於具低成本且能滿足不同操作需求的高效率同步磁阻電動機共同轉子鐵芯之開發，並以相同定子結構為基礎，提出相應的系統化設計流程。首先透過調整轉子鐵芯導磁路徑的設計，實現高輸出轉矩與低轉矩漣波之目的，接著根據不同操作需求，在轉子磁障中加入磁石或導體，以完成共同轉子鐵芯之架構。過程上分別透過理論與模擬的分析，探討磁石與導體的安置對於電動機之影響，最後藉由實測數據驗證有限元素分析軟體所得出的電動機之運轉性能結果。

The purpose of this research is to design a low-cost and high-efficiency synchronous reluctance motor with common rotor iron core structure for various operational requirements. To provide a systematic design based on the identical stator structure, the flux paths in the rotor iron core are first adjusted to achieve high output torque and low torque ripple target. According to various operational specifications, the magnets or conductors are then inserted to the rotor barriers to achieve the respective structural design of the common rotor iron core. During the process, the motor effect of different magnet and conductor arrangement is investigated by theoretical analysis and numerical calculation. Finally, the performance results of the motor design from the finite element analysis are confirmed through experimental measurements.
