Abstract:
A system for rebalancing a generator rotor includes a temporary bearing shield configured to support a non-drive end of the generator rotor, and a pony motor assembly configured for attachment to a drive end of the generator rotor. The pony motor assembly is configured to rotate the generator rotor during a rebalancing operation. The temporary bearing shield and the pony motor assembly enable the generator rotor to be rotated during an in-situ rebalancing operation.
