Claims

[Claims for Utility Model Registration] An armature core of a predetermined thickness is fixed to the rib outer periphery of a ribbed rotating shaft, a commutator is fixed to the rib-free portion of the ribbed rotating shaft, and a commutator is fixed to the ribbed outer circumference of the ribbed rotating shaft. A rotor is provided with an armature coil wound around slots punched out in the rotor, and outside air is introduced through an axial duct formed between the inner periphery of the armature core of the rotor and a rotating shaft with ribs. In a rotor cooling structure for a rotating machine in which air is blown out from a plurality of radial ducts formed in the circumferential direction of a child core to cool the inside of the rotor, a windbreak plate whose outer peripheral portion protrudes into the axial duct is attached to the radial duct. A rotor cooling structure for a rotating machine, characterized in that the outer diameters of the windbreak plates are sequentially increased from the commutator side to the opposite commutator side.
