In the thin steel plates which are used in many industrial products, including those of the automobile industry, flaws on the plate surface and peeling during the surface treatment process are induced due to the use of many rollers in the conveyance process. These lead to deterioration of the quality of the plate surface. In order to solve this problem, the authors proposed a levitation control device for a rectangular steel plate by the hybrid actuator using five electromagnets and thirty permanent magnets. For fundamental consideration we have reported concerning the optimal placement of permanent magnets using free-free beam with 2 permanent magnets. Especially, to consider the interaction of permanent magnets, the distributed attractive force of a permanent magnet to the steel plate was calculated by the finite element method. In this study, to confirm the effectiveness of the modeling, the distributed attractive force model and the local attractive force model were compared.
