ABSTRACT:
An AC magnetic floating apparatus for floating and conveying a conductive floating body of paramagnetic or nonmagnetic metallic material above a line of AC electromagnets, includes a single-phase AC current source having a first frequency for floating the floating body, a three-phase AC current source having a second frequency for conveying the floating body, an adder for adding AC current from the two current source and a supply circuit for supplying the added Ac currents to the line of AC electromagnets. The floating body can be stopped at a desired position exactly with efficient conveyance.
