Abstract: To determine the relative position of movable portions of an assembly, a first magnetic device is coupled to a first portion of the assembly. The first magnetic device has a sensing surface with a number of magnetic poles that provide a magnetization state transition location. An absolute position sensor with a two-state output is coupled to the assembly adjacent the first magnetic device. The output state changes when a magnetization state transition of the first magnetic device moves past the absolute position sensor. A second magnetic device is coupled to the assembly. The second magnetic device creates a cyclically-varying magnetic field proximate its sensing surface. An incremental position sensor is coupled to the assembly adjacent the second magnetic device, and has an output that varies continuously relative to magnetic field angle over at least a portion of one cycle of the cyclically-varying magnetic field of the second magnetic device.

Abstract: The invention relates to a stator for a linear stepper motor and method for its manufacture. A stator (1) for a linear stepper motor includes four stator sheets (2) and two stator windings (4). The four stator sheets (2) are oriented towards each other, provided with bent polar arms, and have two inner stator sheets (2) each defining a sheet recess (3) and two outer stator sheets (2) that are arranged in an offset manner. The four stator sheets (2) are joined into an integral coil body by a stator overmould (6). One of the stator windings (4) is wound onto the coil body between one inner stator sheet (2) and one outer stator sheet (2) and connected with connector pins (12). The four stator sheets (2) and the stator overmould (6) including a stator flange (5) and a pin socket are integrally formed such that radial envelope surfaces of the at least four stator sheets (2) are free from the stator overmould (6). A stator recess (7) inside the stator (1) is arranged centrically in the stator overmould (6).

Abstract: A linear synchronous motor, in which one or more intermediate annular magnetic pole portions and yoke assemblies can be connected easily while positioning the intermediate annular magnetic pole portions, is provided. A fitting concave portion that is opened in an axial direction and a direction away from a direct drive shaft is formed in each connected portion of the intermediate annular magnetic pole portions. A plurality of fitting grooves are formed on an outer peripheral surface of a pair of magnetic cylindrical members at a plurality of portions facing the plurality of intermediate annular magnetic pole portions. The intermediate annular magnetic pole portions are fixedly positioned between the pair of magnetic cylindrical members by fitting a peripheral portion defining the fitting concave portion of the intermediate annular magnetic pole portion into the corresponding fitting groove of the magnetic cylindrical member.

Abstract: A stage device is equipped with a surface plate (30) and a wafer stage (WST) which is mounted on surface plate (30) and has an exhausting port (73) formed on a surface facing the surface plate. In a state where wafer stage (WST) lands on the surface plate, an air chamber (72) is formed in between surface plate (30) and wafer stage (WST). Pressurized gas blows out from exhausting port (73) provided at stage main section (22) into air chamber (72), and self-weight of wafer stage (WST) is cancelled by an inner pressure of air chamber (72). This allows to the wafer stage which has stopped on the surface plate to be moved manually.
