近年來政府積極推廣節能減碳的政策，夏季用電大宗為冷氣空調產品，而帶動整個冷媒壓縮循環系統的心臟為馬達。有鑑於此，本研究利用既有的感應馬達定子，進行同步磁阻馬達轉子設計。由於同步磁阻馬達與感應馬達同樣是在定子輸入三相弦波電壓激磁以產生旋轉磁場，在電裝載一樣的情況下，影響輸出性能主要因素在於轉子之凸極比，直軸電感與交軸電感之比值與差值為主要之設計參數。另外壓縮機在運轉時的震噪有很大部分是來自於馬達的轉矩漣波，因此轉矩漣波的抑制也是同步磁阻馬達的設計重點。
為達到高效率目標，同步磁阻馬達之轉子結構，包括磁障層數、交直軸絕緣比、橋部、肋部和氣隙長度，利用有限元素法分析之軟體Ansys Maxwell，分別進行馬達設計、模擬與分析，並對馬達輸出性能加以探討。最後建立一套完整的設計流程，並以動力計量測實驗驗證模擬分析之正確性。

The synchronous reluctance motor has attracted interest because of reduce unstable magnet costs and conserve energy. In this thesis, the main factor affecting Ld and Lq is the number of flux barriers, the nonmagnetic rotor insulation width, and the width of the connective ribs. Because the stator used in a SynRM is the same as that used in induction motor, the stator of a 0.75KW three-phase induction motor was used to design the 0.75KW SynRM in this study, a SynRM rotor structure design process method are presented. In addition, the simulations of torque, voltage, current, speed, power factor and efficiency are built by finite element method (FEM). The experiment result of the phototype synchronous reluctance motor is very close to the simulation result at the rated output condition, which efficiency achieves 87.2% rather IE4.
The purpose of this thesis is to present information for developing a suitable Synchronous Reluctance Motor rotor geometry design procedure. To have the potential position of the SynRM in industry a performance comparison between this machine and the other most used machines such as the Induction Motor will be presented. Special attention will be paid to the possible rotor geometries of SynRM, because as it has been shown by J. K. KOSTKO,this can directly influence our insight on the machine’s potential abilities. The main task will highlight the most important parameters of the machine that affect its performance. This can be suitably achieved by finite element method analysis. The combined theory and finite element procedure which is suggested here should be used to reduce the number of barriers as much as possible and not to find an absolute optimum design for a certain number of barriers. If only the torque maximization is targeted the procedure will work, but if other parameters like torque ripple and iron losses, especially in the rotor, are considered, then a more detailed model for controlling these two target variables is needed.
