Abstract
This squirrel-cage motor rotor includes a plurality of conductor bars provided at regular intervals along the circumferential direction of a rotor core, short-circuit rings connected to ends of the conductor bars, and reinforcement covers having axial-direction surfaces being in contact with axial-direction-end surfaces of the short-circuit rings. The reinforcement covers are enclosed by casting in the short-circuit rings. Holding rings are attached to the outer circumferential surfaces of the flange portions of the reinforcement covers and the outer circumferential surfaces of the short-circuit rings by interference fit.
