ABSTRACT:
An air baffle is provided to redirect cooling air flow for the stator of an electric motor. The air baffle is provided at the air outlet end of the motor, and extends between the stator frame and the stator coils, so that air is forced to pass through the coils to exit the motor. The baffle is fixed to the coils, but is loosely mounted to the stator frame in a floating manner so that the entire assembly is free to rotate and can have limited longitudinal motion when necessary according to the operating condition of the motor.
