Claim 7:
8. 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,
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 first forward conductor and the first return conductor are electroconductively connected in series by a first horizontal connecting conductor arranged in the stator layer,
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,
wherein the three-phase system comprises a first side and a second side opposite to the first side which extend along the second direction, wherein the first horizontal connecting conductor connects the ends located at the second side of the three-phase system of the first forward conductor and of the first return conductor and the second horizontal connecting conductor connects the ends located at the first side of the three-phase system of the second forward conductor and of the second return conductor, and
wherein the first horizontal connecting conductor and the second horizontal connecting conductor are in the stator layer each configured as transverse connector in the form of conductor paths.
