Abstract
A method for reshaping a winding and introducing the winding into a rotor body or stator body is provided. The method includes preforming a stranded wire to create the winding, such that straight sections of the stranded wire are connected via bent winding head sections of the stranded wire so as to form a wave winding or loop winding. The method also includes introducing the winding into the rotor body or stator body such that the straight sections come to lie in the slots and the winding head sections of the winding protrude on axial end faces of the rotor body or stator body. The method also includes compacting the winding head sections so as to reduce their axial protrusion.

A method for reshaping and introducing a winding into a rotor body or stator body of an electric machine, the method comprising:
- preforming a stranded wire to create the winding, such that straight sections of the stranded wire are connected via bent winding head sections of the stranded wire so as to form a wave winding or loop winding;
- introducing the winding into the rotor body or stator body such that the straight sections come to lie in slots of the electric machine and the winding head sections of the winding protrude on axial end faces of the rotor body or stator body;
- and
- compacting the winding head sections so as to reduce their axial protrusion.
A stator of an electric machine having a stator body with slots and having a winding made of stranded wire, in which straight sections of the stranded wire are connected via bent winding head sections of the stranded wire to form a wave winding or loop winding, the straight sections come to lie in the slots and the winding head sections of the winding protrude from axial end faces of the stator body, wherein the winding head sections are compacted.
A rotor of an electric machine having a rotor body with slots and having a winding made of stranded wire, in which straight sections of the stranded wire are connected via bent winding head sections of the stranded wire to form a wave winding or loop winding, the straight sections come to lie in the slots and the winding head sections of the winding protrude from axial end faces of the rotor body, wherein the winding head sections are compacted.
