Abstract
A generator may incorporate a positively restrained balance ring. A generator may include a rotor core including a rotor, and a balance ring. The balance ring may include a weight. The balancer may include a plurality of balance holes in the ring, at least one of the plurality of balance holes to receive a weighted insert. A method of balancing a rotor of a generator may include mounting a balance ring adjacent to a rotor core, and adjusting weights to be located at one or more of a plurality of positions equally spaced around the balance ring to balance the rotor.
