Patent ID: 7902699

Claim:
A system for managing air flow within an induction motor, comprising: a rotor assembly comprising: a rotor shaft defining a longitudinal axis; a plurality of longitudinally extending conductor bars, each of said conductor bars defining a first bar end region and a longitudinally opposed second bar end region; and a first end ring adapted to be positioned concentrically with said rotor shaft, to be coupled to said conductor bars, to electrically couple said conductor bars, and to substantially impede air flow through a first plurality of radial apertures defined by said plurality of first bar end regions, said first end ring contiguous with a gap blocker, said gap blocker adapted to substantially cover radial apertures defined by gaps between conductor bar end regions and a fan of said induction motor, said gap blocker adapted to be positioned to substantially block a gap defined by said fan and a securement ring, said securement ring adapted to secure a stacked plurality of rotor laminations comprised by of said induction motor.
