  • Patent number: 10224778
    Abstract: An electric motor vehicle coolant pump includes a pump rotor which pumps a coolant and a drive motor which drives the pump rotor. The drive motor includes a dry motor stator comprising motor coils, a wet motor rotor, and a gap tube configured to separate the dry motor stator and the wet motor rotor from each other in a fluid-tight manner. The gap tube is formed by an integral sheet metal body which, in a gap region between the wet motor rotor and the dry motor stator consists of an austenitic high-grade steel comprising a material thickness of <0.5 mm, a hardness of from 200 to 500, a specific electrical resistance >0.10?×mm2/m, and a relative magnetic permeability<20. The integral sheet metal body forms a sheet metal shell sliding bearing shell of a sliding bearing to radially mount the wet motor rotor.

  • Publication number: 20180034181
    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.

  • Patent number: 6552466
    Abstract: A wet-running direct-current motor for a fuel pump having a commutator (2) formed from carbon lamellas (5), and carbon brushes (3) having brush running faces (6) which are fluted in the direction of rotation. The fluting is obtained by curved, parallel ribs of triangular cross-sections whose apexes define the brush running face. The curved ribs have radii offset from the curvature of the commutator surface, the offset being achieved by offset of the center of the radius of each rib in a direction counter to the direction of relative rotation of the commutator and brushes. The motor is rendered usable for fuel pumps of diesel engines.

  • Patent number: 6296458
    Abstract: An electric fuel pump for an internal combustion engine in which a pump mechanism is provided in a housing for pumping fuel from an inlet to an outlet of the housing. A d.c. motor in the housing is drivingly connected to the pump mechanism, the fuel flowing through the housing past the motor to the outlet. A module including a commutation circuit for the d.c. motor is sealed in the housing from the fuel which flows therearound and cools the module. The module is constructed with an injection-molded casing around the circuit which is connected to stator windings of the motor and to an outside power supply.

  • Patent number: 5785013
    Abstract: A pump-motor unit for pumping a coolant for cooling an internal combustion engine in which a centrifugal pump is connected to an electrically commutated d.c. motor to be driven thereby. A power electronic circuit is mounted on a plate and installed in the unit in connection with the d.c. motor to operate the motor in accordance with signals delivered to said power electronic circuit from an external power source. A cooling body is supported in the unit to cool the power electronic circuit by transferring heat from the power electronic circuit to the coolant. The centrifugal pump and the d.c. motor are interconnected through the cooling body.
