Abstract
A method for producing a single- or multi-layer coil, includes the steps of: providing a flat wire; deforming the flat wire along a deforming direction in order to produce one or more winding sections which are designed to be offset relative to a starting section of the flat wire, wherein the one or more winding sections are designed to form coil layers which run on winding planes arranged in an offset manner relative to the deforming direction; and winding the one or more winding sections on the respective winding plane in order to form one or more coil layers.

A method for producing a single or multiple layer coil, the method comprising the steps of:
- providing a flat wire;
- deforming the flat wire along a deforming direction in order to produce one or more winding sections configured to be offset in relation to a starting section of the flat wire, wherein the winding section or sections are designed to form coil layers which run in winding planes arranged in an offset manner relative to the deforming direction;
- arranging the flat wire in a deforming tool in order to produce S-shaped deforming regions;
- and
- winding the winding section or sections within the respective winding plane to form one or more coil layers;
- wherein a first S-shaped deforming region of the S-shaped deforming regions between the starting section and a first winding plane of the winding planes has a different form than second S-shaped deforming regions of the S-shaped deforming regions between the winding planes.
A layer coil, comprising:
- a plurality of coil layers formed from a flat wire,
- wherein the plurality of coil layers include a plurality of winding sections, which are offset in relation to a coil beginning of the layer coil, and a plurality of S-shaped deforming regions,
- wherein the winding sections form coil layers which run in winding planes arranged in an offset manner relative to a deforming direction of the flat wire which is oriented perpendicularly or substantially perpendicularly to the winding plane, and
- wherein a first S-shaped deforming region of the S-shaped deforming regions between the coil beginning and a first winding plane of the winding planes has a different form than second S-shaped deforming regions of the S-shaped deforming regions between the winding planes.
