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.

Abstract: Displacement devices comprise a stator and a moveable stage. The stator comprises a plurality of coils shaped to provide pluralities of generally linearly elongated coil traces in one or more layers. Layers of coils may overlap in the Z-direction. The moveable stage comprises a plurality of magnet arrays. Each magnet array may comprise a plurality of magnetization segments generally linearly elongated in a corresponding direction. Each magnetization segment has a magnetization direction generally orthogonal to the direction in which it is elongated and at least two of the magnetization directions are different from one another. One or more amplifiers may be connected to selectively drive current in the coil traces and to thereby effect relative movement between the stator and the moveable stage.

Abstract: Provided is a means for mitigating strict constraints between a virtual polyhedron inscribed in a rotor and a virtual polyhedron inscribed in a stator of a spherical stepping motor and a spherical AC servo motor and drastically increasing the degree of freedom in design. The above problem is solved by disposing permanent magnets at points of division of the sides of the virtual polyhedron inscribed in the rotor and electromagnets at points of division of the sides of the virtual polyhedron inscribed in the stator. A multiple pole spherical stepping motor and a multiple pole spherical AC servo motor include a rotor with permanent magnets disposed at the vertexes of a virtual polyhedron inscribed in a sphere and at points of division of arcs corresponding to the sides connecting the vertexes, and a stator with electromagnets disposed at the vertexes of a virtual polyhedron inscribed in a sphere containing the sphere of the rotor and at points of division of arcs corresponding to the sides connecting the vertexes.

Abstract: A planar motor system comprises a platen with a first planar motor component and a stage with a second planar motor component. The stage can move along a first cardinal axis or a second cardinal axis. The planar motor system further comprises a drive system. When the drive system is energized in a first drive configuration, it applies a first force and a second force. The first force and the second force are not parallel to any cardinal axis. A vector sum of the first force and the second force is parallel to the first cardinal axis. When the drive system is energized in a second drive configuration, it applies a third force and a fourth force. The third force and the fourth force are not parallel to any cardinal axis. A vector sum of the third force and the fourth force is parallel to the second cardinal axis.
