A counter rotating generator has an outer housing including a cylindrical sidewall defining a pair of openings and a pair of circular mounting plates connected to the outer housing adjacent respective opposed ends thereof. A first shaft and an armature mounted thereon are rotatably mounted on one mounting plate. A second shaft and a field magnet mounted thereon via an inner housing is rotatably mounted on the other mounting plate in a direction opposite the armature. Slip rings are mounted on and encircle the inner housing. A pair of brush assemblies are mounted on the outer housing and extend respectively through the openings in sidewall thereof with brushes contacting the slip rings between and adjacent the inner housing and the outer housing sidewall. The large-diameter slip rings more quickly dissipate heat caused by frictional engagement of the brushes and slip rings, thus allowing the generator to operate at higher rates of revolution and higher temperatures.
