Abstract
A method for controlling a planar drive system includes identifying a preferred stator module direction with a preferred magnetic field or sensor direction, and identifying a preferred mover direction with a respective other of the preferred magnetic field or sensor direction; setting a magnetic orientation field with a magnet device; recording at least a measurement value of the magnetic orientation field with a magnetic field sensor device; determining an alignment of the preferred mover direction relative to the preferred stator module direction based on the measurement value of the component of the magnetic orientation field parallel to the preferred sensor direction; and determining a first orientation of the mover on the stator module, on the basis of the alignment of the preferred mover direction relative to the preferred stator module direction. The application also relates to a planar drive system.
