A segmented stator end turn air deflector for an electric motor having a stator and a rotor. The stator has a plurality of stator coils with end turns and a plurality of air passages extending longitudinally through the stator. A frame having an inlet end and an outlet end surrounds the stator. The rotor is rotatably mounted inside the stator and the frame. Brackets are coupled adjacent to the outlet end of the frame in a circular orientation. An air baffle assembly is coupled with respect to the stator adjacent to the outlet end and extending between, but out of contact with, the frame and ends of the coils for the purpose of directing any air flowing from the air passages onto the end turns. The air baffle assembly includes a plurality of arcuate segments each coupled to a respective one of the brackets. The air baffle assembly further has a radially interior arcuate end and a radially exterior arcuate end and angularly oriented side edges which converge inwardly.

[ What is claimed is:] [1.] An electric motor having improved ventilation for improved cooling comprising a stator having winding end turns at each end thereof, air passages extending generally longitudinally along the longitudinal axis of the motor and positioned generally radially outwardly of the winding end turns, an outer housing around the stator, an end bell at one end of the motor having a plurality of ventilation openings therein at spaced locations around the end bell and a generally annular disc shaped air deflector positioned in the motor longitudially between the winding end turns and the end bell and extending generally radially outwardly from adjacent the winding end turns toward the outer housing, with the deflector comprising a plurality of generally planar segments mounted within the motor in generally side-by-side relation and together redirecting the air exiting the air passages to flow generally radially inwardly past the winding end turns, with each deflector segment being sized to fit through a ventilation opening to enable a motor built without a deflector to be modified to include said deflector without disassembly of the motor.
