When the magnetic wheel facing a conductive plate is rotated at high speed, three-axis magnetic forces are generated. Among them, the levitation and lateral forces have self-stability and do not require a separate controller to be stable. In this study, we introduce a device that moves in space by controlling only the transfer position in a transport device comprising four magnetic wheels. The relationship between the design value of individual magnetic wheels and the range of spatial stability is explained using finite element analysis. In particular, the change in the levitation force according to the overlapping distance from the edge of the conductive plate to the center of the magnetic wheel is described using the induced current density. Because the only control variable in the developed system is the wheel speed, we present a simple logic and test results to transfer the system only by controlling the speed. KCI Citation Count: 0
