Method and one-piece tool assembly for producing a stator for an electrical machine

The disclosure relates to a method for producing a stator, where, for one or both layers of a two-layer winding, a tool with receiving regions is respectively provided on an end face of a laminated core. A relative arrangement of the receiving regions corresponds to a relative end position for conductor ends of the conductor elements. In a positioning process, the tool is moved into a first turning position and each conductor end of a first group of the conductor elements is respectively inserted into one of the receiving regions. Then the tool is turned into at least one further turning position and each conductor end of a further group of the conductor elements is respectively inserted into one of the receiving regions until the conductor ends of all the conductor elements of the layer are in the relative end position in relation to one another.
