Abstract
A fan blade is attached to the shaft of an induction motor by means of a spring clip seated in a groove in the shaft resiliently and frictionally clamping the fan blade against a flat surface of a member secured to the shaft, such as the rotor end ring, thereby providing a perpendicular relationship between the fan blade and shaft and, when the end ring is used, abstracting heat from the rotor.
