  • 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.

  • Patent number: 10180142
    Abstract: 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.

  • 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.
