A high slip induction motor is described wherein the protruding ends of extended aluminum rotor bars are interconnected by cast aluminum end ring strips having an elongated radial length to function as a fan maximizing heat transfer from the rotor bars. The strips preferably are a bifurcated design with a protruding nose at the interconnected end of the strips remote from the rotor bars while juxtaposition of the bifurcated strips forms a pocket between adjacent strips to snugly receive the rotor bars which are then welded to the strips. Radial and arcuate restraint of the extended end of the rotor is achieved by support wheels formed of rotor laminations situated at both ends of the end ring strips to receive the extended rotor bars and protruding noses, respectively, within the conductor slots of the laminations.
