ABSTRACT:
A brush holder support in a dynamic electric machine such as an electric motor includes an electrically insulating support plate which carries on its one side a plurality of brush holders slidably receiving brushes with pig-tails connected thereto. A pair of conductor plates are secured to the other side of the support plate concentrically with one another. The conductor plates are insulated plate from one another by a portion of the support located therebetween. Each of the pair of conductor plates provides electrical connections between the pig-tails of the brushes of the same polarity. The support plate includes notches formed in its inner and outer peripheral edges so as to provide passages for leading the pig-tails from the one side to the other side of the support plate.
