Carrying apparatus having carrier levitated by magnetic force
First Claim
1. A carrying apparatus comprising:
- a track path having a track surface;
magnetic field generating means, provided along said track surface of said track path, for generating, along said track surface, a magnetic field having a predetermined magnetic flux distribution pattern in a direction perpendicular to an extending direction of said track path;
a carrier movably arranged on said track surface of said track path;
at least one superconductor element mounted in said carrier, said superconductor element trapping a magnetic flux of a magnetic field applied during transition from a normal conducting state to a superconducting state and supplying a levitating force and a guide force acting in a direction perpendicular to the extending direction of said track path to said carrier by a magnetic force generated between the trapped magnetic flux and the magnetic field generated by said magnetic field generating means; and
propelling means for supplying a moving force to said carrier in a direction of said track path in a non-contact manner.

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.
