Abstract
An engine driven generator () is provided with first and second stage fans () at one end thereof. The two-stage fan system draws in ambient air and forces it through the generator windings () and rotor-stator air gap () for the purpose of improving generator cooling. Stationary guide vanes () are disposed between the two fans () for the purpose of de-swirling the flow therebetween. The fans are of the centrifugal type and are preferably backward curved.
