Abstract

An oscillation damping system for stator windings is provided which includes a supporting component of an end winding. The supporting component is equipped with damping elements, which are arranged asymmetrically in the circumferential direction in order to suppress excited natural oscillations. Masses or springs and screw-type restraints which connect the supporting component to the stator housing are suitable as damping elements.
