Winding tool for stator winding system

A winding tool for a stator winding system of an electric machine, said winding tool comprising:

• a shell section having tool slots for windings of a number of phases of the stator winding system, said tool slots running parallel to a tool axis of the winding tool, being disposed in a circularly distributed manner about the tool axis and being closed toward the tool axis;
• and
• first and second end parts disposed completely inside the shell section when viewed radially with respect to the tool axis, said first and second end parts being guided by the shell section for displacement in a direction of the tool axis by a shortening section, so that, when viewed in the direction of the tool axis, the first and second end parts are displaceable between a smaller and a greater distance from one another, said first and second end parts including guide surfaces for holding winding overhangs of the windings radially within the shell element during winding of the windings, said first end part including guide elements for guiding the windings in a transition section from sections of the windings disposed in the tool slots to the winding overhangs held by the first end part such that, when viewed in a tangential direction about the tool axis, the guide elements extend over an angle which is smaller than an angle in a region of the shell section,
• wherein the shell section includes guide bevels which guide the winding overhangs wound onto the second end part radially outward after detachment of the winding overhangs from the second end part, so that the winding overhangs are able to slide radially outward along the shell section toward a stator lamination stack of the electric machine.
