摘要： A conveying system includes at least one guide unit and a carrier. The guide unit includes a traveling surface, at least one guide rail, and a magnetic member formed of a soft magnetic material and including a plurality of salient poles aligned along a conveying path. The carrier includes at least one roller coming in contact with the guide rail from a side direction, at least one wheel coming in contact with the traveling surface, and a plurality of coils provided to overlap with the magnetic member in plan view, and configured to generate thrust along the conveying path and attraction toward the magnetic member by generating a moving magnetic field acting on the magnetic member in accordance with supply of power.

摘要： A transport system include: a workpiece holder configured to hold a workpiece; a moving body facing the workpiece holder at least in a gravity direction and movable in a movement direction intersecting the gravity direction; a weight reducer configured to apply a static non-contact force to the workpiece holder to reduce a weight of the workpiece holder; a force generator disposed on the moving body to face the workpiece holder in the gravity direction, the force generator configured to apply a controllable non-contact force to the workpiece holder so as to follow a movement of the moving body while levitating the workpiece holder having the reduced weight; and circuitry configured to control the controllable non-contact force generated by the force generator to control a relative position of the workpiece holder with respect to the moving body.
