A planar drive system comprises a stator and a rotor. The stator comprises a plurality of energizable stator conductors. The rotor comprises a magnet device having at least one rotor magnet. A magnetic interaction can be produced between energized stator conductors of the stator and the magnet device to drive the rotor. The stator is configured to carry out energization of the stator conductors so that an alternating magnetic field can be generated via the energized stator conductors. The rotor comprises at least one rotor coil in which an alternating voltage can be induced due to the alternating magnetic field. The planar drive system is configured to transmit data from the stator to the rotor, and the stator is configured to temporarily influence the energization of the stator conductors in order to temporarily cause a change with respect to the alternating voltage induced in the at least one rotor coil.
