Abstract:
The invention relates to a stator (10) for an electric machine comprising a stator package (12); a stator winding, which comprises a plurality of rod-shaped conductors (16a, 16b), which are inserted through the stator package (12) in an axial direction (A); wherein at least one first conductor (16b) and an adjacent second conductor (16b) of the plurality of conductors are electrically connected to each other on an end face (20) of the stator package (12) by means of a bridge (34) formed by laser welding; wherein the bridge (34) formed by laser welding extends at an angle to the axial direction (A) between the conductor ends (18a, 18b) of the first conductor (16a) and the second conductor (16b).
