Claim 0:
1. A stator assembly for driving a rotor of an electrical planar motor,
wherein the stator assembly comprises:
coil conductors arranged in a stator layer of the stator assembly,
wherein the coil conductors extend in an elongated manner a first direction and are arranged side by side in a second direction oriented perpendicularly with regard to the first direction,
wherein the coil conductors are connected on the stator assembly to form a three-phase system having a first phase U, a second phase V and a third phase W, and
wherein the coil conductors are configured as a first forward conductor and as a first return conductor of the first phase U connected in series with the first forward conductor, as a second forward conductor and as a second return conductor of the second phase V connected in series with the second forward conductor and as a third forward conductor and as a third return conductor of the third phase W connected in series with the third forward conductor;

wherein the three-phase system has a first side and a second side opposite to the first side,
wherein the first forward conductor and the first return conductor are electroconductively connected in series by a first horizontal connecting conductor arranged in the stator layer and at the second side of the three-phase system, and
wherein the second forward conductor and the second return conductor are electroconductively connected in series by a second horizontal connecting conductor arranged in the stator layer and at the first side of the three-phase system.
