A damped rotor system includes a rotor blade defining a longitudinal axis opposed leading and trailing edges and having a blade spar. The rotor blade has flexibility in an edgewise direction defined between the leading and trailing edges. A structural damping assembly has an eddy current damper including a damper body that is mounted to the blade spar. The damper body houses a magnetic member movable relative to the damper body. The damper body is of an electrically conductive non-ferromagnetic material such that movement of the magnetic member relative to the damper body induces magnetic eddy currents in the damper body for damping vibrations of the rotor blade in the edgewise direction.
