Abstract: A rotor has a rotor core with protruding fingers defining slots for conductors and support blocks at the axial ends of the fingers fixed by screws. The fingers have holes for housing the screws. The method for repairing the rotor includes removing the screws and support blocks, drilling the holes to increase the diameter thereof, providing plugs into the holes.
