A grounding brush assembly includes a grounding brush with a plurality of conductive fibers and a mounting plate. The mounting plate includes a radial main body, a plurality of retaining tongues extending from the main body for axially and radially retaining the brush, and either a plurality of centering tabs or an annular centering flange extending from the main body and at least locally surrounding the grounding brush while remaining radially separated therefrom. The centering tabs or flange have/has an outer surface defining the outer diameter of the mounting plate. The mounting plate further includes at least one mounting tongue which protrudes outwardly with respect to the outer surface of the centering means and which is flexible in the radial direction.

A grounding brush assembly includes a grounding brush and a mounting plate. The mounting plate includes a radial main body and a plurality of tongues for axially and radially retaining the brush, the tongues extending from the main body and being spaced apart from one another in the circumferential direction. The mounting plate further includes a plurality of centering tabs which extend from the main body and are offset radially outwardly at least partially with respect to the tongues.

A fluid delivery module includes a housing with a housing interior volume, the housing defining a first brush compartment and a second brush compartment within the housing interior volume; an inlet which introduces fluid into the housing interior volume; an outlet which discharges fluid from the housing interior volume; a fluid pump within the housing interior volume and having a pump section and a motor assembly which receives electric power through a first carbon brush and a second carbon brush such that the first carbon brush is received within a first carbon brush holder of the motor assembly and the second carbon brush is received within a second carbon brush holder of the motor assembly; and a filter within the housing interior volume which circumferentially surrounds the fluid pump. The first brush compartment encloses the first carbon brush holder and the second brush compartment encloses the second carbon brush holder.

A rotating electric machine has a brush holder that holds brushes. A first cover through which a rotor shaft passes is provided on one end side in an axial direction. A brush holder accommodating portion that accommodates the brush holder is recessed in the first cover in the axial direction from an outer side of the first cover. The brush holder is disposed in the brush holder accommodating portion such that a distance between a lower surface of the brush holder and an inner peripheral wall of the brush holder accommodating portion is larger than a distance between another portion of the brush holder and another inner peripheral wall of the brush holder accommodating portion.

An isostatic brush holder (10) comprises a central body (12), one or more arms (14, 14) rotationally disposed in proximity of the opposite ends of said central body (12), and defining a first and a second end (16, 16), and a plurality of brushes (20) cooperating with at least one elastic element (22), where said arms (14, 14) define the respective first ends (16) of quick release snap catches (24, 24), said arms being pivoted to each other at the second ends (16), said arms being further connected in a swivelling manner and in proximity to said second ends (16) at the opposite ends of said central body (12).

A system for mitigating induced currents in an electric motor having a shaft includes: a brush holder having a handle end, the brush holder having: a brush holder handle at the handle end; and a shaft grounding brush attached to the brush holder handle, the shaft grounding brush including a contact at a contact end of the brush holder, the contact end being opposite the handle end; and an end bell of the electric motor, the end bell receiving the contact end of the brush holder such that the contact of the shaft grounding brush contacts the shaft.

A high-voltage accumulator module having a multiplicity of battery cells arranged in a honeycombed parallel- and series connection assembly (for example, honeycomb). The gaps between the battery cells are filled with a thermally and electrically conductive potting compound. The battery cells are electrically insulated with respect to the potting compound. The potting compound is connected to an energy source via electrically conductive fixing elements that protrude into the potting compound and via two pole connections in such a way that a current flow through the potting compound which is as homogenous as possible is achieved. The two pole connections, for example, in the form of metal plates, may be fastened to the potting compound over a large surface area and in close electrical contact therewith by the fixing elements. The fixing elements may protrude as deep as possible into the potting compound in the form of strips or pins and may contain barbs.

A device may include a first end, a second end, and a coupler configured to extend through an aperture from a first side to a second side of a motor cover. The coupler includes a head portion, a conduit portion extending from the head portion towards the second end, and a first bore axially extending through the coupler. The device may include a brush holder extending through the first bore. The brush holder includes a cylindrical body, a socket at the first end, and a receptacle at the second end. The device may include a first lock nut including a first threaded bore axially extending through the nut. The device may be configured to enable a grounding brush to contact a motor shaft to provide a current discharge path to ground to reduce an erosion of the motor components including the motor shaft and rolling bearing elements.

A rotating electric machine has a brush holder that holds brushes. A first cover through which a rotor shaft passes is provided on one end side in an axial direction. A brush holder accommodating portion that accommodates the brush holder is recessed in the first cover in the axial direction from an outer side of the first cover. The brush holder is disposed in the brush holder accommodating portion such that a distance between a lower surface of the brush holder and an inner peripheral wall of the brush holder accommodating portion is larger than a distance between another portion of the brush holder and another inner peripheral wall of the brush holder accommodating portion.

An apparatus according to the invention comprises a brush holder for receiving a brush for transmitting power between a rotating part and a stationary part of a slip ring having at least a first electrically conductive contacting member and a second electrically insulating guiding member.
