A motor vehicle auxiliary assembly electric motor includes a motor stator with stator coils. The motor stator is electronically commutated. A control electronics system drives the stator coils and is potted in a cast body. An electronics chamber is closed-off and has the control electronics system and the cast body arranged therein. A gas chamber is arranged adjacent to the cast body. A pressure equalization element ventilates and vents the gas chamber. An aeration shaft is arranged to pass through the cast body and fluidically connects the gas chamber to the atmosphere. The pressure equalization element is fluidically associated with the aeration shaft.

An electric motor vehicle coolant pump for cooling an internal combustion engine of a motor vehicle includes a pump housing and a rotor rotatably supported in the pump housing. The rotor comprises a motor rotor configured to be substantially pot-shaped. The motor rotor comprises a pot bottom and a ferromagnetic substance so as to be magnetized in at least a bipolar manner. A pump rotor comprises a plurality of rotor blades and an annular cover ring arranged on distal ends of the plurality of rotor blades. The plurality of rotor blades are configured to stand directly on the pot bottom of the motor rotor. The pump rotor and the motor rotor are each integral plastic material parts separately produced by an injection molding. The pump rotor and the motor rotor are made from different materials. The pump rotor is not ferromagnetic.

A housing unit for electrical components for use in the automobile sector includes a housing part configured to be closed in a sealed manner by a housing cover arrangement. The housing cover arrangement comprises a membrane, at least one ventilation opening, a main cover element comprising a recess, and a cover closure element. The recess comprises an opening which is configured to be closed in a sealed manner by the membrane. The opening comprises a rib arrangement which is configured to pretension the membrane. The cover closure element is configured to close the recess so as to provide the at least one ventilation opening.

A wet-type rotor pump which is particularly suitable for feeding coolant in motorcar engines comprises a pump wheel. By the pump wheel, a feed medium is fed through an intake channel into a discharge channel. Via a common shaft, a motor armature of an electric motor is connected with the pump wheel. The motor armature is surrounded by a slit pot, feed medium flowing around the motor armature to cool it. The shaft is supported by two radial bearings, one radial bearing being arranged in a supporting element. The supporting element that is arranged within the intake channel further comprises an abutting surface on which a flow surface of the pump wheel abuts to take up axial forces.

Wet-type rotor pump

The electric motor comprises an internal rotor and an external stator with stator windings. The rotor comprises several permanently magnetic pole shoes. The stator windings are supported by stator pole shanks comprising, radially inside, stator pole shoes facing the rotor pole shoes. Via a short circuit bridge, the stator pole shoes are connected with the adjacent stator pole shoes so that all the stator pole shanks are integrally formed with each other. Radially outside, the stator pole shanks and stator pole shoes are connected with each other only by a separate yoke ring set thereon. All the windings are wound from radially outside with one single continuous winding wire when the yoke ring has been removed.
