Abstract: A stator assembly for driving a rotor of an electrical planar motor includes a first arrangement of longitudinal stator layers and a second arrangement of oblique stator layers. The longitudinal stator layers comprise first coil conductors and the oblique stator layers comprise second coil conductors. The second coil conductors interact with second drive magnets to drive the rotor in a first direction, and the first coil conductors interact with first drive magnets to drive the rotor in a second direction, different from the first direction. The longitudinal and oblique stator layers are arranged on top of one another in a third direction, perpendicular to the first and second directions, where the first arrangement of longitudinal stator layers and the second arrangement of oblique stator layers have a shared central plane, each being symmetrically arranged with regard to the shared central plane, in the third direction.

Abstract: A stator assembly for a planar electrical motor includes coil conductors arranged in a stator layer, elongated in a first direction and arranged side by side in a second direction perpendicular to the first direction. The coil conductors are connected to form a three-phase system, with a first forward conductor a nnd first return conductor of the first phase connected in series to the first forward conductor, a second forward conductor and second return conductor of the second phase connected in series with the second forward conductor, and a third forward conductor and third return conductor of the third phase connected in series with the third forward conductor. The three-phase system has first and second opposite sides. The first forward conductor and the first return conductor are electroconductively connected in series by first and second horizontal connecting conductors arranged in the stator layer on the second and first side, respectively.

Abstract: A position-detection system for a drive having a rotor, which can move along a path, comprises an encoder unit, a signal-detection unit and a signal-processing device. The encoder unit or the signal-detection unit is arranged on the rotor, and the respective other unit is arranged along the path. Furthermore, the signal-processing device is designed to generate a first position signal and a second position signal on the basis of a relative position of the encoder unit and signal-detection unit. The signal-processing device is designed to determine a longitudinal position of the rotor along the path on the basis of phase values of the first and second position signals. Furthermore, the signal-processing device is designed to determine a distance, directed transversely with respect to the path, between the encoder unit and the signal-detection unit, on the basis of amplitude values of the first and second position signals, and to detect an operating state of the drive on the basis of the distance.

Abstract: To operate a load a half bridge includes a switching device with a high-side semiconductor switch and a low-side semiconductor switch. The semiconductor switches are connected in series via their current terminals, and each semiconductor switch may be assigned, via its control terminal, a driving system that switches the respective semiconductor switch on or off according to a drive signal. The load is connectable between the high-side and low-side semiconductor switches. The half bridge may include a load relief device connected to the switching device, e.g., in order to collect energy during a switching process in the switching device. The half bridge can\include an energy recovery circuit configured to feed the energy collected by the load relief device, e.g., a current, to an energy storage device before a further energy collection, e.g., current collection, of the load relief device, during a further switching process in the switching device.

Abstract: A magnet arrangement for interacting with drive coils of an electric motor comprises a first drive magnet, a second drive magnet, and a compensation magnet arranged between a coil-facing side of the magnet arrangement and a coil-averted side of the magnet arrangement. The compensation magnet is arranged between the first drive magnet and the second drive magnet. The first drive magnet has a first cross-sectional area, the second drive magnet has a second cross-sectional area, and the compensation magnet has a third cross-sectional area; e.g., with a coil-facing width of the first cross-sectional area and a coil-facing width of the second cross-sectional area in each case greater than a coil-facing width of the third cross-sectional area, a coil-averted width of the third cross-sectional area greater than the coil-facing width of the third cross-sectional area, and the third cross-sectional area undercuts the first and second cross-sectional area on the coil-averted side.
