摘要: A rotor for an electric rotating machine, improving cooling performance of the rotating machine. D-axis through-holes (26) are provided outside the outer periphery of a rotor core (11), and hollow shafts (15a, 15b) are formed in those portions of a rotating shaft (15) which are not inserted in the rotor core (11). Pressing plates (14a, 14b) for holding the rotor core (11) between them are arranged on axially opposite sides of the rotor core (11). Hollow-shaft wall-holes (25) running through the radial direction are formed in the hollow shafts (15a, 15b) on both sides of the rotating shaft (15). In the surface of each pressing plate (14a, 14b) which surface is in contact with the rotator core (11), there are formed a first annular groove (30) connected to the d-axis through-holes (26) and radial grooves (31) for connecting the first annular groove (30) and the hollow-shaft wall-holes (25) of the rotating shaft (15). Refrigerant supplied through the inside of one hollow shaft (15a) of the rotating shaft (15) is passed through the d-axis through-holes (26) and caused to flow out from the other hollow shaft (15b) of the rotating shaft (15).
