Abstract: An electronic motor vehicle fluid pump includes a pump housing and a motor which is electronically commutated. The motor includes a motor rotor which is permanently magnetized, a motor stator with a stator body and a plurality of stator coils, a cylindrical metal motor can which fluidically separates the motor stator and the motor rotor, and a motor electronics unit with an electric ground terminal. The motor electronics unit is arranged at a dry side of the cylindrical metal motor can and is electrically connected to the plurality of stator coils so as to energize the plurality of stator coils to drive the motor rotor. A pump wheel is arranged to co-rotate with the motor rotor. An electric connection provides a direct electric connection between a motor electronics unit ground terminal and the cylindrical metal motor can

Abstract: An automotive electric auxiliary unit includes an electric motor. The electric motor includes a motor rotor which rotates about a rotor axis, a multi-piece motor stator having stator coils, stator teeth, and a separate ring-shaped magnetic back iron ring, and a plastic motor housing. The separate ring-shaped magnetic back iron ring radially surrounds the stator teeth and is attached to the stator teeth. The separate ring-shaped magnetic back iron ring is overmolded by the plastic motor housing.

Abstract: A motor vehicle pump arrangement includes a pumping unit having engagement steps, and a mounting arrangement which mounts the pumping unit to a motor vehicle mounting structure which corresponds to the pumping unit. The mounting arrangement includes a vibration-decoupling body having a ring shape, and a clip retainer which is attached to the vibration-decoupling body. The vibration-decoupling body radially surrounds the pumping unit, supports the pumping unit, and is attachable to the motor vehicle mounting structure. The clip retainer axially retains the pumping unit. The clip retainer includes a retainer frame which extends in a transversal pumping unit plane and which is axially supported by the vibration-decoupling body, and retainer arms which axially project from the retainer frame. Each of the retainer arms engages a respective one of the corresponding engagement steps of the pumping unit so as to axially retain the pumping unit.

Abstract: A motor vehicle pump arrangement includes a pumping unit and a mounting arrangement. The pumping unit has a substantially cylindrical pumping unit housing and at least one support protrusion which radially protrudes from the pumping unit housing. The mounting arrangement mounts the pumping unit to a motor vehicle mounting structure corresponding thereto. The mounting arrangement has a ring-shaped pump support body. The pump support body radially surrounds and supports the pumping unit and is attachable to the motor vehicle mounting structure. An axial side of the pump support body includes a castellated structure having axially extending merlons and protrusion receptacles. One protrusion receptacle is arranged between two adjacent merlons. The support protrusion engages with at least one of the protrusion receptacles.

Abstract: An electric motor vehicle secondary assembly includes a housing body with a housing opening, a drive motor, a device driven by the drive motor, a connector arrangement with at least two exposed connector pins, a cast body with a connector core integrally molded thereon, and a motor control circuit board which is partially potted in the cast body. The connector core forms a connector base. The connector pins are each formed by a respective single rigid pin element which is directly electrically connected to the motor control circuit board. The connector core of the cast body encloses each pin element between the motor control circuit board and the connector base. The connector core is plugged into the housing opening of the housing body so that the connector base completely closes the housing opening and the pin elements project outward from the connector base through the housing opening.
