Patent ID: 10461612

Abstract:
The invention relates to a planar positioning apparatus, comprising a stator, which comprises a coil arrangement comprising flat coils, a rotor which is arranged opposite the stator in the operating position of the positioning apparatus and has a planar magnet arrangement comprising a plurality of rows of magnets, wherein the plane which is spanned by the planar magnet arrangement is arranged parallel to the plane of the coil arrangement, a position detecting device for detecting the position of the rotor relative to the stator, and an evaluation and control device for evaluating position signals of the position detecting device and for controlling a current supply to the coil arrangement for controlling the position of the rotor with respect to the stator, wherein the coil arrangement comprises in each case n×3 (n≥1) elongate flat coils which are interleaved with one another, in a first and second orientation of the coil arrangement which, over the majority of their extent, are designed as conductor runs of a first plane of a multiple-plane printed circuit board, and the conductor runs of the three associated flat coils enclose crossover regions which run in a second plane of the multiple-plane printed circuit board.
