In the design of a magnetically levitated system the question arises whether the closed loop can be stabilized by a certain active magnetic bearing (AMB). In this paper we introduce several characteristic quantities which evaluate the static and dynamic capacity of an AMB system. A controller design is not necessary in this novel stability estimation. The calculation of the proposed characteristic quantities can be used to estimate how well an AMB is suited for the stabilization task. Furthermore, the derived dimensionless quantities allow easy comparison of different AMB systems.
