Hybrid Magnetic Levitation System for Thin Steel Plates Using Electromagnets and Permanent Magnets

(Experimental Consideration on Vibration Characteristics of Levitated Steel Plates)

Abstract

　In thin steel plate production lines, the problem of surface quality deterioration of steel sheets in contact conveying by rollers has become an issue. As a solution to this problem, we have proposed an energy-saving magnetic levitation system that uses electromagnets for magnetic levitation and permanent magnets for levitation assistance. In this study, an experimental investigation was conducted on the effect of the tension application position on the vibration characteristics of thin steel plates when they are magnetically levitated.
