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.

Automotive electric motor

An automotive single-phase electrical motor of a claw pole type includes a rotating motor rotor which rotates around a rotating axis, a stator defined by a pair of annular stator bodies, and a stator coil arrangement which magnetizes the stator bodies. The stator bodies includes a first stator body having a radial arm and at least two magnetic claws, and a second stator body having a radial arm and at least two magnetic claws. The at least two magnetic claws of the first stator body mesh with the at least two magnetic claws of the second stator body so that the stator bodies mate with each other. The stator coil arrangement is provided as a satellite of the stator bodies. The radial arm of the first stator body and the radial arm of the second stator body are magnetically connected to each other at the stator coil arrangement.

Claw pole type motor

An electric vehicle vacuum pump assembly includes a combination, a separate acoustic barrier casing configured to encase the combination in each of a radially-spaced relationship and an axially-spaced relationship, and an annular gastight attenuation assembly radially arranged between the separate acoustic barrier casing on a first side and the combination on a second side. The combination comprises a pump unit and a drive motor comprising a rotor space, a stator space, a ventilation inlet, and a ventilation outlet. The rotor space comprises a motor rotor, and the stator space comprises a motor stator. The separate acoustic barrier casing comprises an intake connection and a discharge connection. The ventilation inlet and the ventilation outlet of the drive motor are configured to provide a forced ventilation past the annular gastight attenuation assembly and through at least one of the rotor space and the stator space.

Electric motor vehicle vacuum pump arrangement

An electric exhaust gas recirculation valve for an internal combustion engine of a motor vehicle includes a motor rotor. A drive motor is configured to be mechanically commutated. The drive motor comprises a plastic carrier panel lying in a transverse plane arranged at a longitudinal end of the drive motor. The plastic carrier panel comprises, on a side facing the motor rotor, at least two commutator brushes and suppression reactance coils assigned to the at least two commutator brushes. Suppression capacitors are arranged on a side averted from the motor rotor. A valve body. A reduction gearing is connected to the drive motor. The reduction gearing is mechanically connected to the valve body.
