気流で冷却を行うことを特徴とする回転子。[Claims for Utility Model Registration] A plurality of protrusions are provided on the end ring, and a balance adjustment ring is inserted into one or more of the plurality of protrusions to maintain dynamic balance during rotation. In a rotor of a rotating electric machine having a structure for correction, the shape of the protrusions is structured to have a side surface that increases air resistance when these protrusions move, and the balance adjustment ring has a shape such that air resistance increases when the protrusions move. The hole is shaped to fit into at least a part of the outer periphery of the protrusion, and when the rotor rotates within the rotating electrical machine, the protrusion generates an air flow, and this air flow performs cooling. Characteristic rotor.
