摘要： 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.

摘要： The present invention relates to a magnetic levitating transport system for transporting a levitating body composed of conductive paramagnetic or non-magnetic metal above electromagnet arrays by generating an alternating magnetic field in a pair of parallel electromagnet arrays.The dimensions of the levitating body are expressed in relation to dimensions of the electromagnet arrays, as well as, other dimensions of the levitating body. The specific symmetrical shape, having a flat underside, allows the levitating body to manoeuvre a curve having a large curvature. In addition, perpendicular direction changes are effected using transportation passages.
