In this paper we illustrate an analytical numerical model of passive magnetic bearings with axial magnetization. We evaluate the axial stiffness of these bearings versus the air gap, the coaxiality error of the rings polarized, and the direction of the magnetization. With reference to an application example the calculation of the natural frequencies of such a system is evaluated versus the stiffness previously cited.

Abstract
In this paper we illustrate an analytical numerical model of passive magnetic bearings with axial magnetization. We evaluate the axial stiffness of these bearings versus the air gap, the coaxiality error of the rings polarized, and the direction of the magnetization. With reference to an application example the calculation of the natural frequencies of such a system is evaluated versus the stiffness previously cited.File in questo prodotto:
