本文提出的T型半開口平行槽嵌入式梯形感應導體用來提高線性感應電動機（LIM）的推力結構。以三相線性馬達原有矽鋼片導磁結構，使用繪圖軟體建構幾何圖型，再運用有限元素分析軟體模擬分析四種移動子結構與三種固定子型式，分析中有12種組合方式可以實現，並比較12種組合方式的推力和漣波推力，利用電磁場有限元素分析四種結構的推力和漣波推力，並針對這些組合的線性馬達進行推力與漣波推力計算比較分析，模擬結果證明，梯形感應導體加背鐵能夠增加推力及有效氣隙也變小，分析結果顯示推力變的更大。T型半開口的平行槽內嵌式梯形導體具有良好的推力特點，依模擬數據可以估算真正的線性馬達作動時參考依據，因而具有實用價值。

This paper presents the structure of the application of T type Semi-open parallel slots embedded-type ladder conductor to enhance the thrust of the linear induction motor (LIM).In the analysis, 12 cases combinations are achieved through calculating the type size of the motor, constructing geometric forms with graphic application, performing finite element method software to analyze 4 mobile substructure, and combining with 3 fixed sub-type. Compare the thrust and ripple force of these 12 combinations cases, ladder conductor with back iron increases the thrust, and decreases the effective air-gap, and it reveals the amplification of the thrust, as the simulation result. T type Semi-open parallel slots embedded-type ladder conductor possesses favorable thrust; this simulation data can be used as reference basis when estimating practical linear motor performances.
