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.

Abstract: A method is provided for processing an object with the aid of a planar drive system. The planar drive system comprises at least one stator assembly, each having a plurality of coil groups for generating a stator magnetic field, a stator surface above the stator assembly, and at least one rotor comprising a plurality of magnet units for generating a rotor magnetic field. The planar drive system further comprises at least one rotational position, where the rotor is rotatable about a rotational axis perpendicular to the stator surface in the rotational position. The rotational position is determined based on a point of contact of four stator assemblies. The method comprises energizing the coil groups in such a way that the rotor moves to the rotational position, energizing the coil groups in such a way that the rotor rotates, and processing of the object with the aid of the rotor rotation.

Abstract: A planar drive system includes a stator module and a rotor. The stator module has a stator assembly with at least one coil arrangement that can be energized to generate a stator magnetic field above a stator surface, and a magnetic field sensor. The rotor has a magnet arrangement and can be moved above the stator surface via interaction between the stator magnetic field the magnet arrangement. The rotor can be used as an input device or output device, or both. A controller can compare the position of the rotor magnetic field detected with the sensor to the position expected based on energization of the coil arrangement, to determine any deviation of the expected position as an external movement, and to recognize an input thereby. The controller can control an output via a predetermined movement of the rotor, and to energize the coil arrangement so the rotor moves as defined.

Abstract: The invention relates to a planar drive system comprising at least a stator assembly with a plurality of coil groups for generating a stator magnetic field, a stator surface above the stator assembly, and a rotor. The rotor comprises a plurality of magnet assemblies for generating a rotor magnetic field. In a first operating state, the rotor can be moved above the stator surface in parallel to the stator surface with the aid of an interaction of the stator magnetic field with the rotor magnetic field. In a second operating state, the rotor is at least restricted in its ability to move in parallel to and perpendicularly with regard to the stator surface by a safety system.

Abstract: A method is provided for processing an object using a planar drive system having 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 at least one rotor with a plurality of magnet units for generating a rotor magnetic field. A processing element is arranged above the stator surface. The planar drive system has at least one rotational position, where the rotor can be rotated about an axis perpendicular to the stator surface. A spatial arrangement of the processing element is predetermined by the rotational position. The method comprises energizing the coil groups so a rotor with the object arranged on the rotor moves to the rotational position, energizing the coil groups so the rotor rotates, and processing the object with the aid of the rotor rotation, where the processing element acts upon the object.
