Abstract: A planar-drive system includes a rotor and stator module with a housing, a stator assembly for driving the rotor, and a sensor module for detecting the rotor position. The sensor module has a 2D arrangement of magnetic-field sensors arranged on a carrier in first and second periodic grids, extending in first and second directions. Adjacent magnetic-field sensors are arranged at first and second distances in the first and second directions. The grids are shifted by a vector having first and second components smaller than the respective first and a second distances. The rotor has first and second magnet units, each with an arrangement of magnets with first and second periodic lengths aligned in the first and second directions. The first and second components of the vector, and a difference between the first and second distances and the respective components, are each smaller than the respective first and second periodic lengths.

Abstract: A stator module for two-dimensionally driving a rotor having first and second magnet units comprises a stator assembly including first and second stator segments for interacting with drive magnets of the first and second magnet units. The individual stator segments may each be energized independently from the remaining stator segments. The stator assembly comprises first, second, third and fourth stator sectors. The first stator segments of the individual stator sectors each extend in a second direction over all second stator segments of the relevant stator sector arranged side by side, and the second stator segments of the individual stator sectors each extend in a first direction over all first stator segments of the relevant stator sector arranged side by side. Extensions of the stator sectors in the first and second directions are respectively smaller than extensions of a magnet arrangement comprising the magnet units.

Abstract: An output module for connection to a DC voltage intermediate circuit of a drive control system for an electrical drive comprises a frequency converter which is connected between the DC voltage intermediate circuit and an output of the output module, and a module controller for controlling the frequency converter. The module controller is configured to control the frequency converter in a first operating mode of the output module in such a manner that an electrical motor is driven with an electrical drive current from the DC voltage intermediate circuit via the output. The module controller is configured to control the frequency converter in a second operating mode of the output module in such a manner that an electrical feedback current from the DC voltage intermediate circuit is fed back into an electrical supply network via the output.

Abstract: A stator module for driving a rotor of an electrical planar-drive system comprises a power module, a stator assembly arranged on a top surface of the power module, and a connector. The power module is embodied to provide drive currents for driving the rotor. The stator assembly comprises coil conductors electrically connected to the power module via the connector for charging with the drive currents. The power module and the stator assembly each have a plate-shaped embodiment. The power module is mechanically fastened to the stator assembly by the connector. The stator assembly comprises a contact structure with contact holes arranged side by side, and the power module comprises a connecting arrangement with further contact holes arranged side by side. The connector comprises contact pins arranged side by side to engage in the further contact holes of the connecting arrangement, and in the contact holes of the contact structure.

Abstract: A linear motor comprises a stator, the stator comprising multiple drive coils and an intermediate circuit electrically conductively connected to each drive coil, the intermediate circuit being configured to exchange energy with each drive coil. The drive coils are arranged along the running rail, where at least one slide comprising a magnet acting as a rotor of the linear motor is movably arranged on the running rail. A controller is configured to independently control each drive coil, so that electrical energy is fed from the intermediate circuit into the drive coils, if a measured intermediate circuit voltage is greater or equal to a predetermined intermediate circuit voltage threshold value, where those drive coils are excluded from the feed-in of the electrical energy which are instantaneously being used for driving or braking the at least one slide and/or have a thermal load which exceeds a predetermined thermal load threshold value.
