Curved Magnetic Levitation Conveying System for Thin Steel Plate with Magnetic Field Applied from Edge Direction: Fundamental Consideration on Effect of Bending Angle on Levitation Performance

In production lines for thin steel plate, which are widely used for industrial products, contact conveyance is performed by rollers. However, quality deterioration due to contact between the thin steel plate and the roller has become a problem. Therefore, non-contact magnetic levitation transportation of thin steel plates using the attractive force of electromagnets has been proposed. So far, we have studied the levitation performance of a magnetic levitation system that combines a horizontal positioning control system and a curved magnetic levitation system. However, the levitation stability of the levitation performance of the magnetic levitation system, which combines the horizontal positioning control system and the curved magnetic levitation system, when the bending angle of the steel plate is changed has not been sufficiently studied. Therefore, in this report, we experimentally investigated the effect of the bending angle of the thin steel plate on the levitation performance.
