ABSTRACT:
A one-piece, plastic, integrally formed deflector for a motor includes a generally annularly shaped shroud portion, an axially offset generally annularly shaped mounting ring portion, and four generally axially extending webs interconnecting them. The deflector may be conveniently mounted to an end bracket with a screw placed through a mounting hole in the mounting ring located at each web such that as the end bracket is assembled to the motor, the shroud portion closely fits nearly adjacent the rotating rotor blades and the inside of the motor shell to restrict the flow of ventilating air through the motor and prevent its re-circulation past the blades.
