Abstract
A damping device for a rotor supported by an arrangement of magnetic bearings including at least one radial bearing formed of a stator magnet and a rotor magnet, with the damping device, including an intermediate member fixedly connected with the rotor by the stator magnet of the at least one radial bearing, and connected with a stationary part in an axial direction by connecting elements including spherical recesses formed in the intermediate member and in the stationary part and balls located in opposite recesses of the intermediate member and the stationary part, with spherical recesses having a diameter larger than a diameter of the balls, and with the balls or surfaces of the recesses being formed of an elastically deformable material having a modulus of elasticity smaller than a modulus of elasticity of a metal.
