ABSTRACT:
An apparatus for providing ventilating air into a housing for an electric machine is disclosed. The apparatus includes a hub mounted to the housing with a raised center portion and a generally circular outer portion. The center portion is displaced upwardly from the outer portion to form an outer surface. The apparatus features a first plurality of main blades extending upwardly from the hub, a second plurality of auxilliary blades extending downwardly from the hub. Ventilating air is communicated through an axial aperture in the hub, the main blades guiding air at least partially into the central aperture and the auxilliary blades transmitting air through the housing. An apparatus including a blower wheel for providing ventilating air into a housing of an electric machine is also featured. The blower wheel features a generally dome-shaped hub. The blower wheel may feature a third plurality of impeller blades extending downwardly from the hub to transmit air into the housing.
