Abstract
Brush rigging for a dynamoelectric machine such as an electric cranking motor for cranking an internal combustion engine. A support carries a plurality of radially extending brush holders each of which slidably supports a brush. The brushes are urged radially inwardly by an elastomeric band that is formed of electrical insulating material. The band directly engages the outer ends of the brushes and a plurality of pins that are carried by the support. The pins are located between pairs of brush holders.
