Abstract
An apparatus and method for a generator assembly for a drive train such as a rotatable turbine engine assembly. The generator assembly includes at least first and second generators mechanically coupled to the drive train. First and second dampers are operably coupled to the first and second generators, respectively, to selectively damp the first and second generators. Damping the first and second generators can reduce or eliminate both common mode and differential mode torsional oscillations from the generators to the drive train.
