    摘要： An electrical brush comprises a metal-and-carbon containing body and a metallic layer to which an electrical conductor is or may be secured and electrically connected. The metal-and-carbon containing body is sintered with the metallic layer in an area which is greater than the area at the connection of the electrical conductor to the layer.

    摘要： The invention relates to a brush arrangement for a dynamoelectric machine. The brush arrangement includes a brush box having a brush locating surface, a split brush having a first brush portion adjacent the locating surface and a second brush portion remote from the locating surface. The split brush has a bevelled outer end. According to the invention, a pressure plate is secured on the bevelled outer end of the remote brush portion. The plate has a first extension overlying the bevelled outer end of the adjacent brush portion and a second extension which projects as a cantilever from the restore brush portion in a direction away from the adjacent brush portion. The arrangement includes a pressing device engaging the second extension of the plate. In this arrangement, the adjacent and remote portions of the split brush are maintained together and the adjacent portion is maintained against the locating surface of the brush box. In addition, the inner ends of the brush portions are kept together irrespective of the direction of rotation of the collector ring.

    摘要： An electrical contact brush assembly with a brush head and a brush body, the brush head being of resiliently deformable material of mechanical impedance of the same order as that of the brush body, and the brush head being in contact with a top face of the brush body to provide an interface therewith so that high frequency compressive sound waves can pass into the brush head from the brush body and be absorbed to reduce brush bounce. The brush head may be slotted.
