Abstract
An electrical machine with a rotor and a stator. The rotor or the stator has at least one coil with a coil core and a coil winding, which surrounds the coil core. The coil winding has at least one turn that is formed from a flat conductor, which is bent a around a plurality of bending axes, which are spaced apart from one another and are parallel, and, as viewed in section, is S-shaped and/or has a meandering shape. The flat conductor has a plurality of layers that are insulated from one another, at least in regions, and/or a plurality of slot-shaped recesses.

An electrical machine, comprising:
- a rotor and a stator, wherein the rotor or the stator has at least one coil with a coil core and a coil winding, which surrounds the coil core, wherein the coil winding has at least one turn that is formed from a flat conductor, which is bent around a plurality of bending axes, which are spaced apart from one another and are parallel, and, as a viewed in section, is S-shaped and/or has a meandering shape, wherein, for the reduction of eddy currents, the flat conductor has a plurality of layers, which are insulated from one another, at least in regions, and/or a plurality of slot-shaped recesses.
A method for manufacturing an electrical machine with a rotor and a stator, in particular an electrical machine, comprising:
- the rotor or the stator has at least one coil with a coil core and a coil winding, which surrounds the coil core, wherein the coil winding has at least one turn, which is formed from a flat conductor and, as viewed in section, is S-shaped and/or has a meandering shape, and, for the reduction of eddy currents, has a plurality of layers that are insulated from one another, at least in regions, and/or a plurality of slot-shaped recesses and, for the creation of the turn, is bent around a plurality of bending axes, which are spaced apart from one another and are parallel.
