本文主要是以有限元素軟體Flux2D輔助分析與改善單相感應馬達之特性。此馬達由北譯精機馬達製造公司所提供，其輸出扭矩小，且運轉時溫升快且高為其缺點，因此本文首先將針對該馬達之扭矩與溫度問題探討，利用Flux2D建構馬達之幾何構造及建立電路迴路，模擬分析馬達的溫度與扭矩特性，再變更原始設計之匝數、電容、氣隙(Airgap)與積厚等參數，將模擬所得到的結果，取其中的匝數設計變更與馬達實際測試結果比較，得到模擬與實測結果雖然在數值上有落差，但兩者趨勢相當，因此模擬結果具可信度與參考價值。最後配合田口氏實驗計畫法預估各種組合的溫度與扭矩值，以最少的實驗次數獲得理想之設計參數組合，並根據模擬與實測結果之趨勢，以內插法推估此組合的可能實測結果，依新參數所得之扭矩與溫度特性將有所改善。本研究提出Flux2D分析單相感應馬達特性分析與改善之方法，可為工業界對於馬達特性改善之應用。

This research mainly analyses and improves the characteristics of a single-phase induction motor via finite element software Flux2D supplied by PEEI. Because the output torque of this motor is small but the temperature is rising fast, it is required to improve its torque output with relative low temperature rising. The research employs Flux2D to create geometry model of the motor, to set up the circuit, and to analyze the temperature and torsion characteristic of the motor, via changing primary factors such as the circles of winding, capacitor, airgap and thickness of the core. The simulated results were then compared with the experiment results. There is discrepancy between them but the trends of curve are very similar. The simulated results are hence of important reference. The improvement of torque and temperature is then studied. At last, with the Taguchi method, the best achievable values of temperature and torque are estimated. This research provides a method to the analysis and improvement of the motor characteristics by Flux2D. This method can be used by industry for identifying and modification of motor characteristics.
