Claims

[Scope of utility model registration request]

An armature core and a commutator with spaced rings interposed in each predetermined laminated layer are fixed to a rotating shaft, and a rotor is provided in which an armature coil is wound in a slot punched out on the outer periphery of the armature core, and the armature Rotation of a rotating machine in which outside air is introduced from an axial duct provided on the inner diameter side of the iron core in parallel to the rotating shaft direction, and is blown out from a plurality of radial ducts formed in the circumferential direction of the armature iron core to cool the rotor. A rotor cooling structure for a rotating machine, wherein the outer periphery of the spacer ring protrudes into the axial duct, and the outer diameter thereof is increased from the commutator side to the opposite commutator side.
