摘要： A motor vehicle cooling system with an electric coolant pump includes a housing with a pump shaft. The electric coolant pump includes an electric motor in a motor housing. The electric coolant pump is at least partially accommodated in the pump shaft. A clamping device including at least two clamping arms is attached to an upper side of the motor housing. The clamping arms are supported with free ends thereof on an inner side of the pump shaft to clamp the electric coolant pump to the housing.

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.
