文中提出分佈式和集中式兩種繞法在半閉口平行槽移動鐵心梯型感應體構造之推力分析與感應導體在不同厚度的推力關係。並藉由有限元素軟體分析分佈式繞法與集中式繞法的磁通密度和感應導體之間的數據。研究中將線性感應馬達之梯型感應體厚度做為移動子鐵心繞線的實驗因子，利用有限元素分析找出該線性感應馬達之推力分析。分析模擬結果得知本文所提出之半閉口平行槽移動鐵心梯型鋁板感應體結構可以有效的改善線性感應馬達之推力，而分佈式繞法優於集中式繞法，其推力可大幅提高，可做為線性馬達製作開發時的參考依據。

This paper presents the thrust analysis on the structure of the application of semi-open parallel slots moving core ladder shape conductor, as well as the thrust relationship of the conductor with different thickness, based on both distributed and centralized windings. The study applies the data from the finite element analysis on distributed and centralized windings between magnetic flux density and the conductor, the thickness of ladder shape conductor of linear motor as the experimental factor of winding moving core, and finite element analysis to find out thrust behavior analysis of the linear motor. The simulative result of analysis shows that the structure of the application of semi-open parallel slots moving core ladder shape aluminum conductor can effectively improve linear motor thrust, and prove distributed winding, better than centralized one, can promote the thrust significantly. It can also be used as reference basis to develop linear motor.
