In this paper, the stability analysis of a new permanent magnets (PMs) bearings is presented and discussed. The suspension is assured by the repulsive force of properly shaped PMs placed on both the stator and the rotor. Then, exploiting currents induced on a system of null-flux coils attached to the stator, a stabilizing force for the translation of the center of mass of the rotor is obtained. The performance of the proposed bearing is investigated by a research code, previously developed at DESTEC and capable to simulate six degrees of freedom electromechanical devices.

Abstract
In this paper, the stability analysis of a new permanent magnets (PMs) bearings is presented and discussed. The suspension is assured by the repulsive force of properly shaped PMs placed on both the stator and the rotor. Then, exploiting currents induced on a system of null-flux coils attached to the stator, a stabilizing force for the translation of the center of mass of the rotor is obtained. The performance of the proposed bearing is investigated by a research code, previously developed at DESTEC and capable to simulate six degrees of freedom electromechanical devices.File in questo prodotto:
