Abstract: The invention relates to a stator having a multi-phase wave winding made of hairpin conductor elements (5). Each phase consists of two parallel or serially connected branches (6, 6.1, 6.2). Each branch has a first (3.1) and a second (3.2) winding portion, which are connected to each other in series. The slot position of the two limbs (5.1) of each hairpin conductor element alternates by +?1. The first winding portion (3.1) extends clockwise along the stator circumference; the second winding portion (3.2) extends counterclockwise and is connected to the first winding portion via a reverse-connector conductor element (12, 12.1, 12.2). Both limbs of the reverse-connector conductor element (12.1) of the first winding branch (6.1) are located in the uppermost slot position; the limbs of the reverse-connector conductor element (12.2) of the second winding branch (6.2) are located in the lowermost slot position.
