本文為研究適用於低成本量產製程的高效能永磁輔助式同步磁阻電動機轉子結構設計，並提出以既有感應電動機定子結構為基礎的系統化設計流程。此設計流程將由同步磁阻轉子鐵芯優化設計出發，藉由在最佳化設計的轉子磁障中適當的分配永久磁石的安置形式，完成永磁輔助式同步磁阻電動機架構。其中將探討轉子鐵芯導磁路徑的設計、磁石的使用以及量產製程所不可避免的結構調整對於電動機整體效能影響。最終完成電動機實體，並以實體量測結果與有限元素分析所得之動態特性相互驗證電動機之運轉效能。

The purpose of this research is to provide a systematic design of a low-cost and high performance Permanent-Magnet-Assisted Synchronous Reluctance Motor (PMA-SynRM) base on the stator of an existing commercial induction motor. The motor design process started from the rotor design optimization of the synchronous reluctance motor, then the proper placement and usage of magnets, and finally the structural design of the PMA-SynRM. The effects among different flux path designs in the rotor core, the magnets, and the unavoidable structural changes for the massive production consideration were all included. Finally, the PMA-SynRM prototype was built and tested in the laboratory, and the finite element analysis results were confirmed by the experimental measurements.
