回転電機の回転子。A plurality of axial coil slots are provided on the outer circumferential surface of the cylindrical rotor core, and sub-slots narrower than the coil slots are provided at the bottom of the coil slots. A plurality of radial ventilation holes are formed in the coil, the wedge insulating block, and the wedge at intervals in the axial direction, and cooling gas is introduced from the sub-slots and branched into each radial ventilation hole. In the rotor of a rotating electric machine, the size of the wedge of the radial ventilation hole near the end of the core and the ventilation hole of the insulating block below the wedge are determined by the size of the wedge of the radial ventilation hole near the center of the core and the ventilation hole of the insulating block below the wedge. A rotor for a rotating electrical machine characterized by being larger than its size.
