Abstract
The invention provides a method and a device for producing a winding element from a supplied wire, in particular from a round copper wire, said method and device allowing the economical and flexible production of a winding element which, when subsequently used in the field of electrical engineering as a coil or inductor fitted in a stator, ensures the highest possible groove filling factor. For this purpose, the wire is wound to a three-dimensional shape and the cross section of the wire is changed simultaneously, as a result of which separate method steps and therefore tool arrangements for three-dimensional winding of the wire as well as the change of the cross-section of the wire can advantageously be dispensed with.
