Deterioration in the surface quality of steel plates is a problem because steel plates are transported by contact with a roller. A non-contact way of transporting steel plates using electromagnetic force has been proposed as a solution to these problems. In the previous system for magnetically levitating flexible steel plates, it was difficult to levitate thinner steel plates because of the deflection of the steel plates during levitation. To solve this problem, an edge-supported electromagnetic levitation system was proposed. This system is suitable for flexible steel plates and uses electromagnets installed in the horizontal direction. These electromagnets create tension force and suspension force that acts on the steel plates. It is possible to reduce the vibration of flexible steel plates because the tension force suppresses the deflection of the plates. In this paper, the characteristics of tension force on steel plates were investigated by electromagnetic field analysis. Moreover, the relationship between tension force and the reduction in vibration was investigated by experiments using a magnetic levitation system.
