ABSTRACT:
The present invention provides an improved rotor and end connector for an induction motor. The end connector adjoins a rotor core. The rotor core includes a plurality of spaced ventilation openings and defines an aperture for capturing a motor shaft. The end connector should preferably surround and be concentric with the inner ventilation openings. To increase ventilation efficiency, the end connector has a plurality of spaced fan blades. Each of the fan blades has a sloping inner surface and backward curving outer surface. The backward curving outer surface is substantially perpendicular to the end connector, and directs air flow radially outward.
