설계변수에 따른 직선형 유도전동기의 효율 특성 해석

LIM has transverse edge effect by secondary structure causing the variation of equivalent circuit parameters, so 3D FEM must be applied for accurate analysis. This results long analysis time, which is not suitable for its design and characteristic analysis. To overcome the disadvantage, this paper applied analytical method to analyze efficiency characteristic. To derive electromagnetic propulsion force, the electromagnetic field is illustrated, and equivalent circuit method is applied to obtain equivalent circuit parameters.
