Abstract

A stator assembly for a planar electrical motor includes coil conductors arranged in a stator layer, elongated in a first direction and arranged side by side in a second direction perpendicular to the first direction. The coil conductors are connected to form a three-phase system, with a first forward conductor and first return conductor of the first phase connected in series to the first forward conductor, a second forward conductor and second return conductor of the second phase connected in series with the second forward conductor, and a third forward conductor and third return conductor of the third phase connected in series with the third forward conductor. The three-phase system has first and second opposite sides. The first forward conductor and the first return conductor are electroconductively connected in series by first and second horizontal connecting conductors arranged in the stator layer on the second and first side, respectively.
