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.

A manufacturing method of a rotary electric machine is disclosed. The rotary electric machine includes a stator provided with a stator iron core, which is cylindrical and in which slots are formed in a circumferential direction on an inner circumferential surface, and coils of phases that are each inserted into the slots, and a movable element provided with a movable element iron core supported in a rotatable manner relative to the stator and at least a pair of movable element magnetic poles provided in the movable element iron core. The method includes: a split flux coil formation step; a coil setting step; a stator iron core setting step; and a split flux coil collective insertion step.

The invention relates mainly to a method for producing a wound stator (1), including: a step of preparing a phase winding; an insertion step which includes inserting the phase winding into a corresponding series of notches (5) in said stator (1); and an intermediate step of forming lead out wires of the winding (26) each extending between two notches (5) of each series of the inserted phase windings, by applying a first radial force (F1) from an axis (X) of the stator (1) toward the outside of the stator (1), wherein the method also comprises a step of positioning a bearing surface facing at least one notch (5) such as to apply a second radial force (F2) resulting from the application of the first force (F1) from the outside toward the axis (X) of the stator (1).
