BLADE AND YOKE ARRANGEMENT FOR COOLING STATOR WINDINGS

摘要

A fan comprises a hub and a stator coil disposed with the hub. A first set of blades is disposed about the hub. Second blades are disposed on an interior of the hub. An opening is provided through the face of the hub. When the fan is operating, a flow of air passes through the opening which is then captured by the second blades and redirected across the stator coils to provide cooling.
