Abstract
A rotor for an electric motor includes a rotor core defining a plurality of slots that are spaced apart from each other and arranged along a circumferential direction of the rotor core, and a rotor winding provided at the plurality of slots and configured to flow current. The rotor winding includes a plurality of conductor bars that extend in an axial direction of the rotor core and that are disposed in a slot of the plurality of slots, and end rings that are disposed at both sides of the plurality of conductor bars and that connect the plurality of conductor bars to each other. The rotor further includes deformation preventing units each of which surrounds and contacts an outer surface of one of the end rings. The deformation preventing units are configured to restrict deformation of the end rings.
