Abstract
An electric motor cooling fan having a seal ring reduces cooling air recirculation inside the motor which increases the cooling of motor windings for the prevention of motor failures and increases motor reliability. The cooling fan includes two opposed, spaced apart, and substantially circular fan shrouds. A plurality of fan blades extend between and are attached to the fan shrouds. The fan blades are spaced circumferentially around the fan shrouds. The seal ring is coupled to one shroud and extends from an outer surface of the shroud ring. The seal ring has a substantially cylindrical shape and is sized to provide a minimal clearance between an internal air deflector and the seal ring to minimize the flow of air through a space between the shroud ring and the air deflector.
