摘要： 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.

摘要： 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.

摘要： A stator module for electromagnetically driving a rotor of a planar drive system comprises a connection module to provide drive energy. A power module has a current-generating unit to generate a drive current, which drives the rotor, from the drive energy. A stator unit has a coil conductor, to which the drive current can be applied, for generating a magnetic field which drives the rotor. A sensor module comprises a position-detecting unit to detect a position of the rotor over the sensor unit. The sensor module is arranged in a module housing. The stator unit and power module are arranged on a top side of the module housing and the connection module is arranged on a bottom side. The current-generating unit and the connection module are connected via a drive energy line. The drive energy line passes through the module housing in a manner electrically insulated from the sensor module.

摘要： 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.

摘要： A stator unit for driving a rotor of an electrical planar drive system comprises first and second stator sectors. The first stator sector comprises conductor strips extended in an elongate manner along a first direction, and arranged next to one another along a second direction perpendicular to the first direction. The second stator sector comprises conductor strips extended in an elongate manner along the first direction, and arranged next to one another along the second direction. The first stator sector is arranged adjacent the second stator sector in the first direction. A contact structure comprises a first and a second contact unit groups conductively connected to the conductor strips of the first and second stator sectors. The contact structure is arranged on inner edges of the first stator and second stator sectors, with the inner edges are arranged to bear against one another between the first and second stator sector.

摘要： A network module is specified for controlling an automation process via a data network with superordinate and subordinate data paths. The network module is configured to successively receive, during a communication cycle, via the superordinate data path, a first portion of a sum total of first output data transmitted to signal units connected to a first subordinate data path, a first portion of a sum total of second output data transmitted to signal units connected to a second subordinate data path, a second portion of the first output data and a second portion of the second output data. The network module is configured to send the first and second portions of the first output data immediately subsequently to one another via the first subordinate data path and the first and second portions of the second output data immediately subsequently to one another via the second subordinate data path.
