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 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: A drive module for a linear transport system comprises a housing and a stator, wherein a conveying device of the linear transport system with a magnet arrangement can be arranged on the housing. The stator is arranged in the housing, wherein the stator comprises at least one coil arrangement having at least one coil with at least one stator tooth. The coil arrangement is designed to switchably provide a magnetic traveling field, wherein the magnetic traveling field exits from the coil arrangement at the end faces and passes through the housing shells in order to enter into operative connection with the magnet arrangement of the conveying device of the linear transport system on the outer side of the housing for the purpose of forming a magnetic coupling.
