Geometrical Coupling Between Axial And Radial Dynamics Of AMB

The coupling between angular and radial motion in rotors supported by AMB has been studied in a previous paper by the Authors. The present paper generalized these results to conical AMB actuators taking into account also radial-axial coupling. The aim is to assess how much these effects influence the dynamics in the small of the rotor but does not restrict to the traditional linearization. The linearized model is studied together with the complete nonlinear one, to deal also with second-order effects.
