Electric motor comprising a wiring unit, and method for producing an electric motor comprising a wiring unit

An electric motor, comprising:

• a rotor situated rotatable about an axis of rotation;
• and
• a stator having multiple coils, each coil having two coil connections, the stator having multiple stator segments, each stator segment having exactly one coil, the coils being connected to one another by a wiring unit, the wiring unit including a carrier part adapted to accommodate multiple wiring elements set apart from one another, the wiring elements including at least three first wiring elements, each first wiring element including two and/or exactly two contacting regions set apart from one another and a connection region connected to the contacting regions so that the connection region is arranged between the contacting regions, the contacting regions of each first wiring element being connected to, electrically connected to, and/or integrally connected by laser welding to one of the coil connections at a connection point, a region covered by the connection region of one of the first wiring elements in circumferential and radial directions overlapping with a region covered by the connection region of another of the first wiring elements in the circumferential and radial directions;
• wherein each first wiring element includes a first fastening region adapted for positive and/or integral connection to the carrier part, each first fastening region having a first uninterrupted recess in an axial direction, the carrier part having multiple rivet pins extending in the axial direction, a first rivet pin being guidable through each of the first recesses, free ends of the first rivet pins adapted to be reshaped into rivet heads by ultrasonic welding.
