Abstract (en)
[origin: WO2023006612A1] The invention relates to a method for producing a stator comprising a winding, preferably a hairpin winding, for an electric machine, in particular an electric motor or generator, comprising the steps: - introducing, in particular inserting, winding base bodies (13) into stator grooves and - additively applying at least a section of at least one winding head (11, 12), in particular by applying a build-up material in layers and locally selectively solidifying the build-up material by irradiation with at least one beam impinging on the build-up material and stator.
