Abstract (en)

[origin: WO2023218042A1] The invention relates to a stator (2) for an electric machine, comprising a core (4) and a multiplicity of bar conductors that are arranged in a manner distributed radially around the stator and each spaced from one another and that are connected to one another in pairs such that their shape resembles a hairpin. The winding of the stator comprises a shaped stranded wire/hairpin hybrid in which bar conductors each having two end regions are designed as arms of an individual shaped stranded wire (50). The stator furthermore has a multiplicity of interconnection bridges (172, 174), wherein a respective interconnection bridge is arranged between an end region of a first shaped stranded wire and an end region of a second shaped stranded wire. The interconnection bridge establishes a direct electrical connection from the first shaped stranded wire to the second shaped stranded wire. A drivetrain for a motor vehicle having an electric machine in which such a stator is installed is likewise described.
