A Study on the Secondary Side Eddy Current Distribution Analysis of a Short Primary-Short Secondary Single-Sided LIM by the Finite Element Method

단1차 단2차 편측식 선형 유도전동기의 유한요소법에 의한 2차측 와전류 분포해석에 관한 연구

In this paper, a short primary-short secondary single-sided linear induction motor which is used as the driving source for an automatic conveyor system, is selected as an analysis model. The finite element method in which the current vector potential is introduced is adopted to analyze the eddy current distribution and thrust force which are produced according to the relative position of the primary and the secondary. Also, the analysis results are compared with experimental ones, to show the propriety of this model.
