Levitating conveyor

Abstract

Abstract PURPOSE:To reduce the power consumption and to decrease the size of a levitating conveyor by supporting most of magnetomotive force for levitating a conveying vehicle to a permanent magnet, and utilizing the leakage magnetic flux of the magnet to drive the vehicle. CONSTITUTION:The cores of electromagnets 3 made of a magnetic material are mounted on both ends of a permanent magnet 9 for loading most of a magnetomotive force for generating the attracting force to levitate a conveying vehicle 10. The core is slightly elongated in a direction opposed to the motor stator winding group of the lower portion of the electromagnet to form a field of the motor. An armature winding 13 is wound on a bobbin 14 at the stator 15 side. The winding 13 is connected with 3-phase AC power source, controlled for the supplying current by a controller on the basis of a signal from a vehicle position detector, thereby controlling to drive the vehicle 10.
