프린징 효과를 고려한 자기등가회로 기반 자기부상 물류이송시스템의 부상력에 관한 연구

Abstract

In this paper, the EMS(Electro-Magnet Suspension) E-type magnetic levitation system is interpreted through magnetic equivalent circuit. In addition, the system is interpreted through the finite element analysis program, and the improved equivalent circuit analysis method is introduced to reduce the error of magnetic equivalent circuit calculation result. As an improvement method, a magnetic equivalent circuit model with fringing effect is introduced at the teeth of the iron core adjacent to the air gap. Finally, the feasibility of the improvement model is verified by comparing the improved magnetic equivalent circuit model with the FEA result.
