A fluid pump for a motor vehicle, having a housing, an impeller for conveying a fluid through a fluid chamber of the housing, an electric motor with a stator inside a stator space of the housing for driving an electric motor rotor coupled to the impeller, and a containment shell which separates a wet space of the fluid pump from a dry space of the fluid pump. The containment shell joined to the stator is arranged at least elastically compressed between two fastened together housing parts and rests against the stator and a pump stage housing portion, and the containment shell braces the stator against the housing and thereby fixes the stator relative to the housing in the longitudinal direction of the fluid pump.
The invention relates to an electronic assembly (10) comprising: - a printed circuit board (50); - an electronic component (20), mounted on the printed circuit board; - a metal sheet (40) mounted on the printed circuit board and in which a cavity (30) is formed, the electronic component being housed in the cavity and between the printed circuit board and the metal sheet, the cavity being filled with an interface material (300), - a cover plate (80) mounted on the metal sheet and kept spaced apart from the metal sheet opposite the electronic component and from the cavity so as to form a circulation channel (70) configured to admit a refrigerant liquid. The invention also relates to a module (5) comprising the electronic assembly. The invention also relates to a method for manufacturing the electronic assembly.
An electrical machine for a motor vehicle, having a rotor mounted rotatably about a rotational axis and has a hollow rotor shaft which encloses a shaft cavity, the hollow rotor shaft having an axial end with a shaft opening, a stationary lance guided through the shaft opening into the shaft cavity and has a fluid outlet opening, a cooling medium which is guided through the lance and sprayed via the fluid outlet opening onto an inner lateral surface of the hollow rotor shaft, an edge-sealed first outlet opening formed in a wall of the hollow rotor shaft, via which first outlet opening the cooling medium may escape from the shaft cavity, wherein, at a rotation speed n of the rotor of n≥4,000 rpm over at least 15 seconds, an average film thickness dF of the cooling medium in the radial direction of the rotor is ≤3 mm.

BRUSH ADJUSTER FOR EXTERNAL EXCITATION OF A ROTOR, WHICH IS ARRANGED ON A ROTOR SHAFT, OF AN ELECTRIC MOTOR, ARRANGEMENT OF A ROTOR SHAFT OF AN ELECTRIC MOTOR AND A WET-RUNNING, ELECTROMAGNETICALLY ACTUABLE BRUSH ADJUSTER, ELECTRIC MOTOR, VEHICLE AND METHOD FOR OPERATING AN ELECTRIC MOTOR
The invention relates to a brush adjuster for external excitation of a rotor, which is arranged on a rotor shaft, of an electric motor. Here, the brush adjuster (2) has a first and a second contact brush (4, 6), each of which can be pressed against an associated slip ring (8, 10) of the rotor shaft. The contact brushes (4, 6) can be spring-pretensioned against the slip rings (8, 10) by means of an armature (18) of an electromagnet (12) and a supporting section of the electromagnet, the supporting section interacting with the armature (14) by means of a spring (20), wherein, by means of a coil former (16) of the electromagnet (12), an electromagnetic force which acts in or against a pretensioning direction of the spring (20) and can be variably adjusted depending on requirements can be impressed onto the armature (18) in order to intensify or lessen a contact pressure on the contact brushes (4, 6) by means of the spring (20) and in so doing avoid lifting off of the contact brushes (4, 6) during operation of the electric motor. The invention also relates to an arrangement, an electric motor, a vehicle and a method for operating an electric motor.
The invention relates to an electronic assembly for a motor vehicle, which assembly comprises a housing (B) with at least one coolant pipe (C), and a cover (F) closing the housing (B), defining a controlled leakage space (E) with respect to an inner wall (PI), allowing two parts of the pipe (C) separated by the inner wall (PI) to communicate with one another. The assembly allows cooling to take place by contact with the housing (B) outside the pipe (C). The invention also relates to a motor vehicle and a method based on such an assembly.
