摘要

本文設計一台應用於自動鑽孔攻牙機之內藏型永磁同步電機，額定功率7.5 kW，額定轉速18,000 rpm，最高轉速24,000 rpm。首先配合攻牙機的尺寸與特性要求，選擇最合適的電機型式與槽極數，進行雛型設計，接著使用有限元素軟體進行電機的特性分析，再針對平均轉矩、轉矩漣波、與效率等三項使用模糊田口法結合有限元素分析作優化，最後完成組裝與測試。

This paper is about designing an interior permanent magnet (IPM) synchronous motor used in automatic drilling and tapping machines. It has rated power of 7.5 kW, at a speed of 18,000 rpm. The maximum speed can reach 24,000 rpm. Based on the machine's size limitation and required performance, a suitable machine configuration and a slot-pole number are selected, and then the finite element software is used for analysis of the characteristics. To yield the desired performance, average torque, torque ripple and efficiency, the fuzzy-based Taguchi method coupled with the finite element method (FEM) analysis are used to refine the motor structure. Finally, the motor is constructed and tested.
