摘要： A laminated carbon brush for a liquid pump motor slides in a liquid fuel on a disk-like commutator. The laminated carbon brush includes two layers of a lower resistivity layer and a higher resistivity layer. In both the lower resistivity layer and the higher resistivity layer, circular directional resistivities of the brush along a circular direction in the rotation of the commutator are higher than non-circular directional resistivities of the brush along a radial direction of the commutator and a perpendicular direction to the sliding surface of the commutator. A non-circular directional resistivity of the higher resistivity layer are higher than or equal to 90,000 µ ©·cm. No spark discharges occur if the fuel pump motor is operated to output a high power.

摘要： A carbonaceous material is fabricated by kneading of carbon powder and a binder. The carbonaceous material is granulated such that an average particle diameter of the carbonaceous material is 0.3 mm or more. A brush material is fabricated by mixing of the granulated carbonaceous material and metallic powder. A ratio of the metallic powder to a total weight of the brush material is adjusted to 1 % by weight or more and 30 % by weight or less. Pressure molding is performed on the fabricated brush material, and thermal processing is further performed on the brush material at a temperature at which a resin in the brush material is not carbonized.

摘要： An electrical connector (100) includes a body (102) having a bore (104) and an interior surface (110). The bore (104) is sized to receive a cable conductor (20) of an electrical power cable (14). The body (102) includes a groove (120) disposed along a length of the interior surface (110). A wire brush insert (140) is located within the groove (120) and includes a plurality of bristles (144) that extend into at least a portion of the bore (104). Rotating the cable wire brushing connector (100) relative to the cable conductor (20) cleans the cable conductor (20) prior to securing the cable conductor (20) within the cable wire brushing connector (100).

摘要： The invention relates to a method for producing a brush (30) for a commutator motor (14), particularly for a motor vehicle fan (2), for electrically contacting a connected contact lead (42) to a commutator (26) by means of spring-loaded contact with the commutator (26). According to said method, a brush material (66), particularly carbon dust, is poured into a cuboid matrix (60) and compressed by means of a plunger (62, 70) in the contact direction (38). The invention also relates to such a brush (30) and to a commutator motor (14).

摘要： The invention relates to an electric machine, in particular a commutator machine (10), the carbon brushes (14) of which cooperate with a commutator (13) to supply the rotor with current, the carbon brushes (14) being continuously provided or provided in layer sections with different additives such as scouring material, lubricants or similar. To achieve a longer service life for the carbon brushes (14), a maximum of half, preferably less than half of all the carbon brushes (14) of the machine have a significant fraction of an additive, said fraction differing from that of the other carbon brushes (14).

摘要： The present invention relates to a brush 10 suitable for coming into contact with conducting plates 12 provided on an electric motor commutator 11. According to the invention, the brush has a means 15 for adjusting its pole coverage between the start of life of the motor and its stabilized operation. This is therefore a brush with pole coverage that can be varied over its operating life. Such a brush is more particularly fitted into a motor for a ventilation (air conditioning) system for motor vehicle.
