Abstract
PURPOSE:To improve the reliability of a rotary electric machine by laying a cylindrical damper with comblike teeth axially inside a retainer ring fitted by shrinking to the end of a rotor field coil and engaging a retainer ring for a damper with the outer periphery of the cylindrical damper, thereby preventing the heating of the field coil retainer ring. CONSTITUTION:A cylindrical retainer ring 9 is engaged through an insulating column 7 with a field coil end 4a, is fitted by shrinking to the shrink fitting part 8 of a rotor body 1, and a cylindrical damper 10 having a comblike teeth 11 and a shortcircuit ring 12 is laid axially inside the ring 9. A retainer ring 15 for a damper is engaged with the outer periphery of the damper 10, and is fitted by shrinking to the body 1 at the shrink fitting part 16. Thus, the damper 10 can be mounted irrespective of the mounting structure of the ring 9, thereby preventing the heating of the ring 9 and its fitting part 8.
