Abstract

Disclosed is a method for pulling a stator winding system of an electric machine into a stator lamination stack of the electric machine and to a winding tool, with the stator lamination stack having stator grooves which run parallel to a rotation axis of the electric machine and are distributed in a circle around the rotation axis and open thereto and which have on an end facing the rotation axis a gap region which is narrowed relative to the rest of the stator groove. Windings are arranged in the stator grooves, and winding overhangs, as seen in the direction of the rotation axis, protrude from the stator lamination stack at the two axial ends thereof, with the windings formed in the stator grooves as laid windings. The stator lamination stack has no guide structures on the two axial ends for guiding the individual turns of the windings.
