PURPOSE:To prevent the slip-off of a transported article from a transfer passage by permitting the reverse excitation in the horizontal direction each other by an alternating magnetic field and restricting the position in the horizontal direction of the transported article which is levitated through magnetism, in a magnetic levitating apparatus for transporting a nonmagnetic article. CONSTITUTION:Single-phase electric power source is supplied into a levitating force applying part 5 and a horizontal pushing-force applying part 6. A nonmagnetic body 1 is levitated by receiving a floating-up force FY. At the same time, said body 1 receives the horizontal pushing forces FY and -FX directing towards the center in the direction of width by receiving the action of the repulsive force generated by the eddy current due to the horizontal magnetic field of the horizontal pushing-force applying parts 6 and 6. therefore, the nonmagnetic body 1 is restriction-held at the center of a transfer passage, and floated-up. At this time, the pushing forces FY and -FX are directed in the direction of width, and do not give an influence to transportation. With such constitution, the slip-off from the transfer passage for a transported article can be prevented. |
