Abstract (en)
[origin: US2008030099A1] A carbon brush for an electrical machine for pivotable support on a brush holder of the electrical machine includes a bearing portion embodied on the carbon brush itself for pivotably supporting the carbon brush. This can be done in the form of a bore of a cylindrical portion. This has the advantage that the position of the carbon brush relative to the commutator does not vary especially markedly even in the event of major temperature fluctuations. Moreover, the carbon brush can be well positioned in a brush holder which assures a precise association with the commutator.
