Abstract

The invention relates to a method for producing a coil winding which consists of one or more coil layers. If a coil winding has a plurality of coil layers, the individual coil layers have different numbers of turns, which mainly decrease from the inside to the outside. In order to guarantee identical coil layer heights, the cross-profile of the conductors or the conductor bundles is adapted by deforming the same. The aim of the invention is to make sure that the individual turns of the coil layers are wound neither at too high a pressure nor to loosely. For this purpose, the conductors or conductor bundles are deformed by means of a deformation device in a single process step at the same time as the deformed conductors or conductor bundles are insulated and the conductors and conductor bundles are wound. The height of the already wound part of the coil winding is continuously compared as the actual value with the theoretical value for the already wound part, a theoretical lead for the part of the coil layer to be wound is determined and the deformation device is adjusted in such a manner that the final axial length or height of the coil layer corresponds to a desired value or to the theoretical value. The invention also relates to a corresponding winding device.

Description

technical field [0001] The invention relates to a method for manufacturing a coil winding consisting of one or more winding layers consisting of substantially rectangularly shaped wires or wire bundles; and a method for manufacturing a coil winding consisting of one or more Winding device for coil windings composed of winding layers consisting of substantially rectangularly shaped wires or bundles of wires. Background technique [0002] For coils, in particular dry-insulated coreless choke coils with two or more cylindrical winding layers electrically conductive and parallel connected concentrically nested with a gap remaining, it is known that The winding layers are wound from rectangularly shaped wires or wire bundles, the individual winding layers having a different number of turns, preferably decreasing from the inside to the outside. [0003] The basic structure of concentrically nested electrically conductive parallel winding layers is known from the prior art, for ex...
