Magnetically Levitated Transport Ultra Thin Steel Plate Using Horizontal Positioning Control

(Fundamental Consideration on the Levitation Performance)

Abstract

Thin steel plates are widely used in various industrial products. However, there are problems where deterioration of surface quality and metal plating occurred by transporting. As a solution to these problems, a noncontact transport of steel plate using electromagnetic force has been proposed. However, there is a risk that side slipping or the dropping of the plate may occur. Therefore we have proposed the addition of electromagnetic actuators to control the horizontal motion of levitated steel plate. In this study, we examined the change in the levitation stability during non-contact transport with the addition of positioning control in its horizontal direction in the case of changed transport coditions. As a result, it is confirmed that the application of a magnetic field in the horizontal direction improves the levitation stability of transported thin steel plate in different transport conditions.
