Abstract
A reverse flow, gas cooled dynamoelectric machine includes a rotor mounted fan at each machine end for circulating gas coolant throughout the machine. Improved pressure and efficiency for the fan is achieved by positioning stationary guide vanes upstream from the fan for directing gas coolant into the fan blades at an optimum angle. The invention is directed toward an improved guide vane assembly construction and composition.
