ABSTRACT:
A rotor for use in a rotary electric machine, which rotor includes a rotary shaft, a core on the shaft, windings wound around the core and having axial end portions thereof protruded from the axial ends of the core respectively, retaining rings each fixedly mounted on the shaft and extending around the outer peripheral surface of each protruded end portion of the windings for preventing each protruded end portion from being radially outwardly moved during the rotation of the shaft, and shielding layers each positioned between the inner peripheral surface of each retaining ring and the outer peripheral surface of each protruded end portion of the windings for preventing the cooling gas from being in contact with the inner peripheral surface of each of the retaining rings.
