ABSTRACT:
A system for supporting a retaining ring on an end of body portion of a rotor in an electrodynamic system includes an end wedge which is adapted to be in contact with a retaining ring, a damper bar having a first surface which abuts the end wedge member and a second, oppositely facing surface; and a filler block positioned between the second surface of the damper bar and a field winding portion of a rotor. The filler block has a tapered surface which defines a stress-reducing gap between the field winding portion and the retaining ring, so as to minimize stress in the slot cell and field windings during high-speed rotation of the rotor.
