ABSTRACT:
A dual-face, internally-mounted cooling fan is provided in a dynamoelectric machine, e.g. an alternating current generator. The generator includes a ventilated housing supporting a stator assembly and a rotor assembly. The fan includes a divider disk having a plurality of blades provided on each surface and is mounted to rotate with the rotor assembly. As the fan is rotated, a plurality of separate air currents are drawn axially into the housing for cooling. The divider disk prohibits substantial mixing of currents drawn from opposite ends before they are radially expelled from the housing.
