Abstract

A stator assembly for driving a rotor of a planar electrical motor includes longitudinal stator layers with first coil conductors and inclined stator layers with second coil conductors. The first coil conductors extend in an elongated manner in a first direction, and the second coil conductors extend in an elongated manner in a second direction, different from the first direction. The longitudinal and inclined stator layers are arranged on top of one another in a third direction, oriented perpendicularly to the first and second direction. An uppermost and lowermost stator layer of the stator assembly are each formed as a longitudinal stator layer with first coil conductors. The longitudinal stator layers are arranged in the third direction at most on one side next to an inclined stator layer, and the inclined stator layers are arranged in the third direction at most on one side next to a longitudinal stator layer.
