Abstract
A method for producing a coil winding which is intended for drawing into a stator, a rotor or a drawing-in tool, is of a wave-like form, includes opposing layers and has a plurality of individual wires with wire webs and end windings, and the wire webs are respectively arranged between two successive end windings along the length of the individual wires, and the end windings form lateral regions of the coil winding, the method including pressing the opposing layers of the coil winding by means of a pressing pressure commencing in the one middle region of the wire webs and continuing or migrating outwards to reach into the region of the end windings.

A method for producing a wave-like coil winding for drawing into a stator, a rotor or into a drawing-in tool, the coil winding including opposing layers, which coil winding has a plurality of individual wires with wire webs and end windings, and the wire webs of the individual wires are arranged in each case between two successive end windings and the end windings form lateral regions of the coil winding, the method comprising:
- compressing the opposing layers of the coil winding with a pressing pressure beginning in a middle region of the wire webs and continuing outwards into a region of the end windings,
- wherein the coil winding is wound or mounted on a former before compressing,
- and wherein the former has a droplet shape laterally in cross section.
