Abstract
A brush holder assembly for a dynamoelectric machine. The assembly comprises an annular metallic support plate that carries a plurality of metallic brush holders. Each brush holder slidably supports a brush. Two of the brush holders have tangs that extend from a respective brush holder. A bus bar formed of copper is welded to the tangs to thereby support the bus bar from the brush holders. The brushes that are associated with the two brush holders are each connected to a brush conductor. The brush conductors are welded to the bus bar. Another conductor or lead is welded to the bus bar to feed current to the bus bar.
