Abstract:
An XY-table includes a separate drive for reversing the direction of movement of the table. A ferromagnetic rib projects at one edge of the table and extends perpendicular to the direction of movement of the table to be reversed. The drive has a magnetic yoke for receiving the rib when the table is near a reversal point, the free ends of the magnetic yoke having pole shoes which concentrate a magnetic flux in the yoke, switchable with the aid of a reversal coil, in an air gap through which the rib extends into the interior of the yoke.
