  • Publication number: 20250253751
    Abstract: A planar drive system includes first and second planar drive partial systems. A rotor is movable above a first stator surface in at least two directions, with the aid of first drive elements. The rotor has rotor drive elements for this purpose. The first planar drive partial system also includes a first controller with which the first drive elements can be actuated. The rotor can be moved above the second stator surface in at least two directions with the aid of second drive elements, if the rotor is arranged above the second stator surface. The second planar drive partial system further includes a second controller with which the second drive elements can be actuated. The first stator surface is adjacent to the second stator surface. In a transition area, the rotor is driven cooperatively by the first planar drive partial system and by the second planar drive partial system.

  • Patent number: 12160141
    Abstract: A method for controlling a planar drive system includes determining values of magnetic stator fields for different energizing currents and spatial regions in a two-dimensional array of magnetic field sensors, generating at least one magnetic stator field by applying energizing currents to stator conductors to electrically control a rotor, determining measured values of a total magnetic field via the magnetic field sensors for a plurality of the spatial regions to determine a position of the rotor, compensating contributions of the magnetic stator fields to the measured values of the total magnetic field determined by the magnetic field sensors, generating measured values of the magnetic field determined by the respective magnetic field sensors for the respective space regions, and determining a position of the rotor based on the generated measured values of the magnetic fields. The planar drive system includes at least a controller, a stator module, and a rotor.

  • Publication number: 20240178737
    Abstract: A planar drive system has at least one stator assembly with a plurality of coil groups for generating a stator magnetic field, a stator surface above the stator assembly, and first and second rotors. The rotors each have a plurality of magnet units for generating a rotor magnetic field. The rotors can be moved above the stator surface in first and second directions, with the aid of an interaction of the stator magnetic field with the rotor magnetic field. A connection can be formed between the rotors with the aid of a coupling device. A controller is arranged to output control signals to the stator assembly. The stator assembly is configured to energize the coil groups on the basis of the control signals so that movements of the rotors, coordinated with one another with respect to the coupling device, are carried out with the aid of the stator magnetic field.

  • Publication number: 20230107323
    Abstract: A method for controlling a planar drive system includes controlling a rotor along a control path starting from a first position on a stator module, and determining a sensor pattern for magnetic field sensors of a sensor module. The sensor pattern includes a subset of the magnetic field sensors with at least one of the magnetic field sensors not comprised by the sensor pattern, and an area of the sensor pattern is at least partially covered by the rotor in a position along the control path. The method includes measuring values of the rotor magnetic field with the aid of the magnetic field sensors of the sensor pattern, detecting the rotor, and determining a second position of the rotor based on the measured values. The invention further relates to a planar drive system.
