本計畫針對高效率外轉子永磁同步馬達試量產進行製程品質分析。首先透過Kano顧客需求模型同步評估製程品質目標及顧客需求。為有效改善關鍵製程技術，藉由利用品質機能展開（QFD）工具，重新檢視外轉子馬達各製程站與品質目標之關聯性，找出關鍵製程因子並進行製程優化。此外，透過實驗設計（DOE）手法，找出馬達貼磁製程之最佳化製程參數，有效獲得磁石最大貼合強度，包含：毛刷式塗膠方法、適當之塗膠量與烘烤時間。同時，亦利用實驗設計（DOE）方式得出馬達成品組立之最佳參數，包含：蓋、殼體組立模具之設計方式、伺服壓床扭力值等。

This project conducts process quality analysis for the trial mass production of high-efficiency external rotor permanent magnet synchronous motors. This paper firstly evaluates the process quality objectives and customer needs simultaneously through the Kano customer demand model. In order to effectively improve the key process technology, the Quality Function Deployment (QFD) tool is used to re-examine the correlation between each process station of the outer rotor motor and the quality target, find out the key process factors and carry out process optimization. In addition, through the Design of Experiments (DOE) method, the optimal process parameters of the motor magnet sticking process were found to effectively obtain the maximum sticking strength of the magnet, including: brush coating method, appropriate amount of glue and baking time. At the same time, the design of experiments (DOE) method is also used to obtain the best parameters for the assembly of the motor products, including: the design method of the cover, the shell assembly mold, the torque value of the servo press, etc.
