Abstract
A method for facilitating damping torsional or ring vibrations of a dynamoelectric machine including a rotor assembly with a first amortisseur bar and a second amortisseur bar extending therefrom and terminating at an endring is provided. The method includes providing a damping assembly, and positioning the damping between the first amortisseur bar and the second amortisseur bar such that the damping assembly contacts the first and second amortisseur bars, and is substantially proximate the endring or alternatively the damping assembly is positioned only over one amortisseur bar.
