Abstract
A carrying apparatus having a carrier levitated by a magnetic force. The carrier is movably arranged on the track surface of a track path. A plurality of permanent magnets for generating along the track surface a magnetic field having a predetermined magnetic flux distribution pattern in a direction perpendicular to the extending direction of the track path are provided on the track path. A superconductor element is mounted in the carrier. The superconductor element traps (pins) the magnetic flux of the magnetic field which is applied during transition from the normal conducting state to the superconducting state. The superconductor element supplies a levitating force and a guide force acting in a direction perpendicular to the extending direction of the track path to the carrier by the magnetic force generated between the trapped magnetic flux and the magnetic field generated by the permanent magnets on the track path. The stator of a linear induction motor and magnetic plate which supplies a moving force to the carrier in the direction of the track path in the non-contact manner are provided below the track surface of the track path.
