摘要

摘 要
本研究係利用行進波發展新型球型壓電馬達，此球型馬達由定子與轉子兩部份所構成。將設計之曲面壓電致動器依欲獲得之行進波運行方式分別予以貼附於球殼定子適當位置，施予具相位差之交流訊號產生行進波而驅動轉子。本研究包括利用ANSYS軟體進行球殼定子之模擬分析，分別探討單軸及雙軸球型馬達之各種重要設計參數之影響並與實驗比較。又為提高球型馬達整體效能，球殼定子加入溝槽之機構設計藉以降低雜波之干擾，並設計預壓負荷機構提高定子與轉子之能量轉換效率。藉由所設計之測試平台測試驗證球型馬達之轉速與扭力輸出效果，並評估系統功能。

Abstract
A new type of piezoelectric spherical motor by means of traveling wave is developed. The spherical motor comprises of the stator and rotor. Curved piezoelectric actuator is designed in order to attach to the spherical surface. A series of the curved piezoelectric actuators are laid in a line around a spherical surface. Applying appropriate voltage signal with phase difference on the neighboring actuators, traveling wave is thus generated on the hemispherical shell. Design and analysis and experiment for one and two DOF operation are presented in this article. An FEM software (ANSYS) is used to analysis the hemi-spherical stator. For performance improvement, groove on hemi-spherical shell along the ceramics actuators is designed to avoid from the disturbance wave so that can guide the rotation direction as well as preload mechanism is designed to increase the rotation efficiency. A test bed is designed on which experiment is carried to measure the rotation speed and torque of the spherical motor and verify its system performance.
