摘要： A pump unit assembly includes an electric motor with a printed circuit board carrying a controller, a pump driven by the electric motor, a housing surrounding the printed circuit board, and a plug connector which is fixed to an outside of the housing by a flange. The plug connector covers an opening of the housing and includes contacts directly electrically contacting the printed circuit board and passing through the opening of the housing. The connector includes a pressure compensator including a sintered filter to vent the housing.

摘要： An electrically driven gerotor pump has a gerotor which comprises a stationary outer gerotor element with an inner toothing that is axially delimited by two chamber walls, wherein each chamber-forming root section of the inner toothing is paired with a pressure valve which is connected to the outlet. The gerotor also comprises an inner gerotor element with an outer toothing which is guided in the outer gerotor element in a circumferential manner on an eccentric section of the shaft and is mounted in a rotatable manner so as to mesh with the inner toothing.

摘要： An electric motor includes a rotor and a stator including a stator core and coils. The coils are defined by a winding wire including winding wire ends electrically contacted with a printed circuit board at an end surface through connectors. The connectors each include at least two insulation displacement contacts receiving a winding wire end of a stator winding. Each connector includes a single electrical connection to the printed circuit board. The connector includes a base body with an underside in contact with the printed circuit board. Each of the at least two insulation displacement contacts includes a clamping slot perpendicular to the underside of the base body. The clamping slots are defined by spaced legs extending from the base body, at least two of the spaced legs being resilient.

摘要： A pump includes an electric motor with a rotor mounted rotatably about an axis of rotation and circumferentially surrounding a stator that includes a stator core and coils wound on the stator core. The windings are defined by a winding wire with winding wire end sections electrically contacted directly with a printed circuit board at an end surface through insulation displacement contacts each including at least one opening for insertion of a winding wire end section, the at least one opening being a slot extending parallel or substantially parallel to a surface of the printed circuit board.

摘要： A pump includes an electric motor with a rotor rotatably mounted about an axis of rotation and circumferentially surrounding a stator. The stator includes a stator core and coils wound on the stator core. The windings are made of a winding wire including winding wire end portions which are electrically contacted with a circuit board on an end side. The rotor, the stator, and the circuit board are surrounded by a motor housing which is adjoined by a pump housing, the circuit board being electrically contacted with an intermediate plug to contact the circuit board with an electrical controller. The intermediate plug includes contacts which are injection-molded into the intermediate plug, are electrically contacted with a first end at the circuit board, include a second end arc directed at least partially radially outwardly, and are introduced into a connecting region of the intermediate plug.

摘要： An electric coolant pump is used as an auxiliary water pump in a vehicle. The pump includes radial mounting of the shaft (4) is provided by means of a coolant-lubricated radial sliding bearing (41) arranged between the pump impeller (2) and the rotor (32). A dry-running electric motor (3) with a radially inner stator (31) and a radially outer rotor (32) is accommodated in a motor chamber (13) separated from the pump chamber (10). A shaft seal (5) is between the radial sliding bearing (41) and the motor chamber (13). The rotor (32) is bell-shaped with an inner surface facing the shaft seal (5) and being fixed to the shaft seal (5) to axially overlap with the shaft (4). The motor chamber (13) has an opening to the atmosphere, which is closed by a liquid-tight pressure equalization membrane (6) that is permeable to vapor.

摘要： A pump includes an electric motor with a rotor mounted rotatably about an axis of rotation and surrounding a stator circumferentially. The stator includes a stator core and coils wound on the stator core, the coils being made from a winding wire with winding wire end sections electrically contacted at an end surface with a printed circuit board. The printed circuit board is surrounded by a plug assembly circumferentially with respect to the axis of rotation. The plug assembly includes contacts which are electrically contacted at a first end with the printed circuit board and are directed radially outwardly at a second end in order to define a plug to contact the printed circuit board with an electrical controller.
