ABSTRACT:
A brush holder assembly for use in an electric motor or generator has an insulating ring one side of which carries a set of several equidistant carriers for brushes which are biased in the radial direction of the ring to bear against a slip ring or against a commutator. Each carrier is radially adjustably secured to the ring by two screws or bolts and nuts whose shanks extend through two elongated slots provided in a flange-like extension of the carrier. Each extension has a tongue extending into a radial groove in the one side of the ring. The axial position of each carrier relative to the ring can be changed by inserting one or more shims between the extension and the ring.
