ABSTRACT:
A carrier transport device is provided with a stator table comprised of a plurality of stators 4 which themselves are comprised of cores 2 and coils 3, and a carrier C in which permanent magnets m1-m4 are provided such that by passing an appropriate current through the coil, the cores of the stators are magnetized. The attraction or repulsion generated between the cores of the stators and the permanent magnets of the carrier is used to transport the carrier along the stator table in two dimensions. This carrier transport device allows for transport of a carrier in two dimensions with a simple design for quick transport of a carrier, and for reliably bringing the carrier to a stop at a predetermined location.
