Abstract
An electrodynamic machine includes a rotor assembly, a stator assembly defining an annular core receiving the rotor assembly, the rotor assembly rotating within the stator assembly based on electromagnetic fields generated by the stator assembly and the rotor assembly, a plurality of structural components mechanically supporting the rotor assembly and stator assembly, and an active damping element providing forced vibrations that counteract structural vibrations of the electrodynamic machine caused by magnetic forces based upon the electromagnetic fields or caused by mechanical forces based upon the plurality of structural components.
