Claim 18:
19. A method for producing an electric motor as recited in claim 1, comprising:
providing a substantially annular carrier part made of an injection molded insulating material;
placing multiple first wiring elements on the carrier part in a circumferential direction, the first wiring elements having two and/or exactly two contacting regions, the first wiring elements being placed such that a region covered by one of the first wiring elements in the circumferential and a radial direction overlaps a region covered by an adjacent first wiring element in the circumferential and radial directions, the first wiring elements being arranged at a distance from one another;
connecting the first wiring elements to the carrier part in a positive and/or integral manner to form a wiring unit; and
connecting, electrically connecting, and/or integrally connecting by laser welding each of the contacting regions of the first wiring elements to a coil connection of one of a plurality of coils having two coil connections arranged on a stator of the electric motor to connect the coils into a multiphase winding.
