���磁石と永久磁石による薄鋼板のハイブリッド磁気浮上システム

In thin steel plate production lines, contact conveyance by rollers is used, so scratches on the surface of the plates and plating defects are problems. Therefore, non-contact magnetic levitation conveyance of thin steel plates using the attractive force of electromagnets has been proposed. We studied a magnetic levitation system for thin steel plates that uses both electromagnets and permanent magnets. We investigated the effect of a permanent magnet arrangement optimized by a genetic algorithm on the levitation performance of steel plates. As a result, it was confirmed that the levitation performance of steel plates changes depending on the permanent magnet arrangement.
