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.
