A brush assembly for use in a brush holder assembly of an electrical machine is disclosed. The brush assembly includes a carbon brush, an electrically conductive terminal and an electrically conductive lead assembly attached to both the carbon brush and the electrically conductive terminal. In some instances, the electrically conductive lead assembly includes a spliced union located between the electrically conductive terminal and the carbon brush and spaced away from both the electrically conductive terminal and the carbon brush. In some instances, the electrically conductive terminal includes an inner core layer positioned between a first conductive metal layer and a second conductive metal layer.

A motor apparatus provided with a connector unit (40) to which an external connector is connected, wherein the connector unit (40) has a plurality of conductive members (64, 65, 66) arranged over a base portion (50) and a connector connecting portion (70) provided with a plug-in hole in which the external connector is plugged, wherein the conductive members (64, 65, 66) respectively include connector-side connecting portions (64a, 65a, 66a) connected to the external connector so as to face the connector connecting portion (70) from a first direction reversed to a plug-in direction of the external connector to the plug-in hole and base-side connecting portions (64b, 65b, 66b) connected to terminals or wirings provided in the base portion (50), wherein the connector-side connecting portions (64a, 65a, 66a) are respectively inserted into a plurality of insertion holes (74, 75, 76) provided at positions different from each other in a second direction intersecting the first direction, and wherein the base-side connecting portions (64b, 65b, 66b) are respectively arranged at the same position in the second direction.

A brush holder assembly including a quick disconnect assembly for quickly disconnecting a brush and electrical leads from a remaining component of the brush holder assembly to facilitate brush removal and replacement. The quick disconnect assembly includes a receptacle having a cavity for removably receiving and an end of the electrical lead, such as the nugget, and a resilient clip. When positioned in the cavity of the receptacle, the resilient clip urges a surface of the nugget into direct contact with a surface of the receptacle partially defining the cavity, completing an electrical current pathway from the brush through the electrical lead to the nugget, and from the surface of the nugget to the surface of the receptacle.

Each cross-section of the connector member assembling hole and the assembly main body 51a in a direction intersecting the insertion direction has a point-symmetrical circular shape with the insertion shaft center FC as the center. A pair of connector-side female terminals 57a, opposed to each other with the insertion shaft center FC as the center, is provided at the distal end side in the insertion direction of the assembly main body 51a, and a pair of brush-side male terminals, opposed to each other with the insertion shaft center FC as the center and to which the connector-side female terminals 57a are connected, is provided to a portion of the brush holder opposite to the connector member assembling hole. Therefore, it is possible to insert the connector member 50 into the gear case in the state of being rotated by 180 degrees about the insertion shaft center FC, and it is possible to cope with arrangement needs which are different by 180 degrees in a connection direction of the external connector, using one connector member 50.

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 brush for a starter-generator includes a first carbon block, a second carbon block, a terminal lug, and a plurality of brush leads. Each carbon block has an outboard edge and an inboard edge. Each carbon block includes a front carbon wafer and a rear carbon wafer. Front brush leads connect the terminal lug with the front carbon wafers of the respective carbon blocks adjacent the inboard edges of the respective carbon blocks. Rear brush leads connect the terminal lug with the rear carbon wafers of the respective carbon blocks adjacent the outboard edge of the respective carbon blocks.

Devices and methods of use for brush holder assemblies are disclosed. Brush holder assemblies including a mounting block and a brush holder are disclosed. Also illustrated is a brush holder assembly including a first portion in sliding engagement with a second portion. In some embodiments the brush holder includes a channel, such that at least a portion of the mounting block is disposed within the channel of the brush holder.

The invention relates to a contacting part (5) for a drive module (1), comprising: a main body for providing contacting of a brush-commutated drive motor (2) by means of brushes; at least one supply line (62), in particular a punched-grid line (62), for electrically contacting the drive motor (2); a circuit surface (57), to which a conducting track is directly applied by means of an MID technique; and at least one component (59), in particular a surface-mounted device (59), which is electrically connected to the conducting track (58).

The invention relates to a discharge device for discharging electrostatic charges from a shaft comprising a flexurally elastic conductor having a carbon fiber arrangement comprising at least two conductor portions (21, 22), which are arranged on a holder, extend transversely to a longitudinal axis of the shaft and are insulated from the holder and which can be connected to a ground conductor (42) via their portion ends (40, 41), which are accommodated in the holder, each of the conductor portions having a shaft contact portion (30, 31), and the shaft contact portions together forming a contact arrangement for making contact with two circumferential contact regions (33, 34) of a shaft circumference (32, 35) arranged opposite each other in a shaft contact plane W, such that the shaft contact portions are arranged tangentially to the shaft circumference when making contact with the shaft circumference.
