摘要

在馬達的設計與分析上，熱傳問題是一項重要的課題，因為熱傳遞特性將直接影響到尺寸與壽命。設計可靠且經濟的高壓高頻馬達，必須預先瞭解馬達內部構造的溫度分佈情形。為解析熱傳問題，本研究以具灌注環氧樹脂膠263線圈之無刷永磁馬達為研究對象，使用軟體FLUENT 5.5模擬灌注膠之熱傳導與馬達參數之溫度分佈，並利用實驗量測驗證之，最後利用田口方法來求得最佳的製程組合，以降低熱傳遞問題。分析所得之數據可用於馬達製程設計之參考，期能達成提高產品良率。

On the design and analysis of motors, the thermal problem is an important subject because the size and life of motors are affected by the thermal characterization. To design a reliable and economical high voltage and high frequency motor, it is necessary to be able to predict accurately the temperature distribution within the motor physical geometry. For thermal analysis, this study presents thermal analysis of a brushless permanent magnet motor with 263 coils and epoxy resins. The temperature distribution solutions carried out by FLUENT 5.5 are used to determine the relationship between the thermal conductivity of epoxy resins and the motor based parameter. The predictions by software have been verified by experiments, and agreement between the numerical and the experimental data has been found. In addition, the Taguchi method is used to find optimal processing condition to reduce the thermal problem. The data presented in this report have been used to improve the quality of practical motor designing processes and reduce the failure rate.
