Abstract
PURPOSE: To increase the hardness of the brushes and reduce the wear and damage thereof caused by its sliding on the commutator, by using Ag-Pd-Cu or Ag-Pd-Ni alloy for the brushes.
CONSTITUTION: The brushes 1 are formed of, for example, a phosphor bronze plate (PBS) (commonly used for springs) applied with Ag-Pd-Cu alloy plating, and the commutator 2 is formed of laminated copper surface plate having its surface etched and applied with B, Ni, Ag-Co plating, so that sliding wear between them is reduced.
