Abstract

A stator assembly for driving a rotor of an electrical planar motor includes a first arrangement of longitudinal stator layers and a second arrangement of oblique stator layers. The longitudinal stator layers comprise first coil conductors and the oblique stator layers comprise second coil conductors. The second coil conductors interact with second drive magnets to drive the rotor in a first direction, and the first coil conductors interact with first drive magnets to drive the rotor in a second direction, different from the first direction. The longitudinal and oblique stator layers are arranged on top of one another in a third direction, perpendicular to the first and second directions, where the first arrangement of longitudinal stator layers and the second arrangement of oblique stator layers have a shared central plane, each being symmetrically arranged with regard to the shared central plane, in the third direction.
