摘要： A machine includes a moving part and a direct drive for moving the moving part. The direct drive includes a stator and an armature unit which interacts with the stator. A coupling device couples the armature unit to the moving part to allow a movement of the moving part in relation to the armature unit. The direct drive further includes a spacer device to maintain a distance between an active region of the stator and an active region of the armature unit, thereby defining the air gap between the stator and the armature unit.

摘要： The invention relates to a short stroke linear motor. In order to improve the dynamics of such a short stroke linear motor, the primary part (12) of the motor is provided with a single-strand winding. The primary part (12) and the secondary part (1) have essentially the same pole pitch (tZ=tM). In this way, a very high motor torque is produced in a limited range of displacement. In order to be able to reach a plurality of working positions without an inactive intermediate position, a short stroke linear motor having a double-strand winding is additionally provided, both strands being operated at a phase difference of

摘要： The aim of the invention is to create an inexpensive sensor system for a movable electric machine in order to determine positions, the sensor signal featuring zero crossings. Said aim is achieved by a sensor device (1) comprising a U-shaped yoke (3) and a sensor (10) which is disposed in/on the yoke (3) to detect a magnetic variable, for example. Magnets (6 to 9) that are or can be inversely magnetized are arranged at a free end of the yoke (3). Opposite magnetic fluxes that can be detected by the sensor (10) can be generated in the yoke (3) in accordance with the position of the magnets (6 to 9) relative to one of the pole teeth (11, 12, 13) of a machine component. Approximately sinusoidal sensor signals can be generated therefrom without having to use several measuring sensors, e.g. in order to regulate a linear motor.
