  • Patent number: 4445056
    Abstract: In an electric motor operating with a liquid filled housing, friction and hydraulic losses are reduced and heat removal is improved. A first collar is mounted on the end of the stator coaxially therewith. A second collar is positioned in proximity to the first collar. An annular plate extends from the second collar and faces the end of the rotor. The plate is spaced from the end of the rotor and from the rotor shaft. The rotor has a surface opposing the annular plate. The collars and annular plate form a liquid turbulence reducing shroud for the end of said rotor. The opposing surfaces of the annular plate and rotor move liquid outwardly toward the stator bore and the collars divert the liquid down the air gap for heat removal purposes. The first collar protects the end turns of the stator from abrasion by the moving liquid.
