A two sided radial fan draws cooling air into axially opposite ends of a dynamoelectric device drawing the flow of air into one axial end of the device and directing the flow of air over the device exterior surface, and drawing a second flow of air into an opposite axial end of the device and through the interior of the device before redirecting the second flow of air over the exterior of the device. The two sided fan thereby provides greater cooling efficiency to the device without significantly increasing the size of the fan or the device and without significantly increasing the costs or adding additional components to the device construction.
