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