ABSTRACT:
An air deflector mountable within an electric motor adjacent the outer periphery of a cooling fan within the motor and adjacent the stator winding end turns of the motor so as to inhibit circular flow of air within the motor and to ensure axial flow of air through the motor. In a first embodiment of the air deflector of this invention, the deflector is mounted on the stator through-bolts extending axially from the stator core of the motor, the through-bolts holding the end shields in place on the motor shell. In another embodiment of this invention, the deflectors are forceably inserted in the stator winding end turns and are held in place by the end turns and by the motor shell and are held captive between the stator core and a motor end shield.
