本論文主要之目的在設計一直流無刷線性管狀馬達。其設計流程先以基本磁路理論計算出管狀線性馬達的特性，再依據所應用方面之需求去定義規格及基本尺寸，並以美商Ansoft公司之Maxwell EM 2D分析軟體加以驗證所計算的結果，最後依其最終之最佳設計的尺寸及規格實作一直流無刷線性管狀馬達。此外，本論文提出一種設計方法，利用定子鐵心兩側嵌入兩組軸對稱的尼龍(Nylon)製之線性軸承，以降低原有動子作動時與支撐裝置所產生的摩擦力與頓轉力(Cogging thrust)，達到線性管狀馬達高效率且直驅的實現。除了理論分析與模擬驗證外，本論文亦提供實驗控制結果。 The purpose of this paper is to design a linear tubular brushless DC motor. The motor dimensions are determined based on the required rating. A set of magnetic circuit models are used to calculate the basic motor characteristics and the design which has the application is selected. The static and dynamic performance of the designed motor are calculated and verified with a finite element software. Besides, the paper advance a design method, bracing to used linear bearing that made of Nylon to reduce friction and cogging thrust force. A prototype motor and driver is built to verify the performance of the motor experimentally.
