An automotive electric motor with a mechanical commutation. The automotive electric motor includes a stiff coil wire comprising a welding portion and an end portion which is arranged adjacent to the welding portion, and a flexible braid wire with a wire end which is electrically and mechanically connected to the stiff coil wire at the welding portion via a welding. The end portion of the stiff coil wire includes an end surface. The end portion of the stiff coil wire is bent in relation to the welding portion so that the end portion is bent away from the flexible braid wire and the end surface of the end portion of the stiff coil wire does not face the flexible braid wire.

What is claimed is: 1. An automotive electric motor with a mechanical commutation, the automotive electric motor comprising: a stiff coil wire comprising a welding portion and an end portion which is arranged adjacent to the welding portion, the end portion comprising an end surface; and a flexible braid wire comprising a wire end which is electrically and mechanically connected to the stiff coil wire at the welding portion via a welding, wherein, the stiff coil wire is bent between the welding portion and the end portion so that the end portion is bent in relation to the welding portion, so that the end portion is bent away from the flexible braid wire, and so that the end surface of the end portion of the stiff coil wire does not face the flexible braid wire. 2. The automotive electric motor as recited in to claim 1 , wherein a bending angle of from 60°-120° is defined between the welding portion and the end portion of the stiff coil wire. 3. The automotive electric motor as recited in to claim 1 , further comprising: a welding area which faces in a direction which is substantially orthogonal to a longitudinal direction of the end portion of the stiff coil wire. 4. The automotive electric motor as recited in claim 1 , further comprising: a pocket, wherein, the end surface of the stiff coil wire is inserted into the pocket. 5. The automotive electric motor as recited in claim 1 , wherein the end surface of the stiff coil wire is fixed in the pocket. 6. The automotive electric motor as recited in to claim 1 , wherein the end portion of the stiff coil wire comprises a sharp edge. 7. The automotive electric motor as recited in claim 1 , wherein the stiff coil wire defines a choke coil. 8. The automotive electric motor as recited in claim 1 , wherein the flexible braid wire defines a brush wire of a mechanical commutator arrangement. 9. The automotive electric motor as recited in claim 1 , wherein the end surface of the stiff coil wire is a surface which is generated by a cutting process.
