Achievement of Stable Magnetic Levitation of a 0.18mm Thick Steel Plate and Verification of Levitation Stability Against Various Disturbances

Abstract

Realization of a magnetic levitation and conveyance system for very thin steel plates has been desired to keep the plate surfaces to be intact. However, it is very difficult to levitate thin steel plates stably, due to its magnetic saturations and its flectional characteristics. Nevertheless, we have already performed stable levitation of 1.6mm thick steel plates. In this paper, we will achieve stable magnetic levitation of a 0.18mm thick steel plate, and confirm its stability against various disturbances considered in an actual process and conveyance line.
