摘要： A linear transport system comprises at least one carriage which has at least one permanent magnet and at least one roller, an energizable stator device which has multiple coils, and a guide rail which is arranged on the stator device and which serves for guiding the carriage. The guide rail comprises a running surface for the rolling of the roller of the carriage, such that the roller can roll on the running surface during a displacement, guided by way of the guide rail, of the carriage, wherein at least one electrical contacting device is provided which is formed separately from the roller and which is designed to form an electrical connection between the carriage and the guide rail during the displacement, guided by way of the guide rail, of the carriage.

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 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 two-dimensionally driving a rotor having first and second magnet units includes a stator assembly with first and second stator segments configured for interacting with drive magnets of the first and second magnet units. The individual stator segments can each be energized independently from the remaining stator segments. The stator assembly includes 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 including the first and second magnet units.

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.
