摘要

永磁馬達具有高功率密度、高響應、體積小等優點，近年來廣泛應用於民生與工業產品。為追求更好的馬達品質，常有提高最大轉矩、降低轉矩漣波、提高效率等需求，為達成這些最佳化設計，需考量諸多馬達設計參數，如定子槽型、磁鐵厚度等。然而最佳化設計往往需要大量的模擬實驗，本文引用田口法大幅減少實驗次數，取得符合目標的最佳設計結果。

Permanent magnet motor has the advantages of high power density, high response, small volume, etc., and has been widely used in livelihood and industrial products in recent years. In order to pursue better motor quality, there is often a need to increase the maximum torque, reduce the torque ripple, and improve the efficiency. In order to achieve these optimized designs, many motor design parameters, such as stator slot shape, magnet thickness, etc., need to be considered. However, optimal design often requires a large number of simulation experiments. This article uses the Taguchi method to significantly reduce the number of experiments and achieve the optimized design results conforming to the goals.
