An air cooled diode-rectified alternating current generator for use on motor vehicles. The generator has an internal fan located within the slip ring end frame and an external fan located adjacent the outer wall of the drive end frame. The internal fan cooperates with a baffle having a central opening and forces cooling air between air inlet openings and air outlet openings formed in the slip ring end frame. The air that traverses this path cools one end of a stator winding and a bridge rectifier. The external fan causes a flow of air between air inlet openings and air outlet openings formed in the drive end frame and this air contacts an opposite end of the stator winding. The cooling arrangement also provides for a flow of cooling air from the air inlet openings in the slip ring end frame to the air outlet openings in the drive end frame.
