Abstract

See full text

A planar drive system comprises a stator and a rotor. The stator comprises a plurality of stator conductors. The rotor comprises a magnet device comprising at least one rotor magnet. The stator is configured to energize the stator conductors. A magnetic interaction can be produced between energized stator conductors of the stator and the magnet device of the rotor in order to drive the rotor. The stator is configured to carry out the energizing of the stator conductors by a current control based on a pulse-width modulation. Due to the current control, a ripple current in energized stator conductors of the stator and thereby an alternating magnetic field can be generated. The rotor comprises at least one rotor coil in which an alternating voltage can be induced due to the alternating magnetic field.
