摘要： In a rotor of a rotary-electric machine, in order to improve a cooling performance of a rotor winding, in a rotor winding on an end portion of the rotor in an axial direction, the rotor winding being held by a retaining ring of the rotor winding formed by laminating a plurality of conductors in slots of a rotor iron core extending in an axial direction and having a plurality of slots formed at predetermined intervals in a peripheral direction, ventilation channels through which cooling air flows are formed in the surfaces of the conductors along a longitudinal direction. The ventilation channels have air inlet holes which guide the cooling air and exhaust holes which exhaust the cooling air, the conductors provided with the ventilation channels which are formed in the surfaces of the conductors along the longitudinal direction and through which the cooling air flows are laminated to constitute the rotor winding, and the conductors include openings of the air inlet holes in bottoms of the conductors on a side opposite to a side on which the ventilation channels are formed.
