Publication number: 20240113597Abstract: An automotive electrical liquid pump includes a pump housing which is defined by a pump housing body, a static heat-conducting separating can having a can part and a radial can flange part, an electric motor which drives the automotive electrical liquid pump, a printed circuit board with electronic components for driving the electric motor, and a non-rotatable heat-conducting cooling sleeve. The separating can fluidically separates a wet zone from a dry zone within the pump housing. The electric motor comprises a non-rotatable motor stator arranged within the dry zone and a rotatable motor rotor arranged in the wet zone. The motor rotor is co-rotatably connected to an impeller wheel via a rotatable rotor shaft. The cooling sleeve is arranged to circumferentially surround the motor stator within the dry zone and to be in a direct physical heat-transferring contact with each of the motor stator and the separating can.Type: ApplicationFiled: December 14, 2020Publication date: April 4, 2024Applicant: PIERBURG PUMP TECHNOLOGY GMBHInventors: JENS TEUBEL, RONALD RATHKE

Patent number: 10224778Abstract: 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.Type: GrantFiled: January 14, 2015Date of Patent: March 5, 2019Assignee: PIERBURG PUMP TECHNOLOGY GMBHInventors: Vladimir Popov, Maik Waberski, Ronald Rathke, Jens Teubel

Patent number: 10180142Abstract: 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.Type: GrantFiled: August 4, 2010Date of Patent: January 15, 2019Assignees: PIERBURG PUMP TECHNOLOGY GMBH, KOLEKTOR MAGNET TECHNOLOGY GMBHInventors: Jens Teubel, Ronald Rathke, Martin Fiedlschuster, Michael Weinert, Norbert Weber, Pietro Giannico, Friedel Schlusnus

Patent number: 5785013Abstract: 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.Type: GrantFiled: December 5, 1996Date of Patent: July 28, 1998Assignee: Pierburg AGInventors: Walther Sinn, Frank Langner, Wolfgang Weller, Wolfgang Zacher, Jens Teubel, Ronald Rathke
