ANALYTICAL AND NUMERICAL MODELING OF PASSIVE MAGNETIC BEARINGS

The paper presents the theoretical aspects of passive magnetic bearings (PMBs), the analytical computation and numerical simulation of four cases for PMB with NdFeB permanent magnets in order to obtain the stiffness and magnetic forces for different static displacements of ring shape magnets. Also i...

Zusammenfassung:The paper presents the theoretical aspects of passive magnetic bearings (PMBs), the analytical computation and numerical simulation of four cases for PMB with NdFeB permanent magnets in order to obtain the stiffness and magnetic forces for different static displacements of ring shape magnets. Also in this paper it is presented a comparison between the two computational methods with the results of the relative errors that have been obtained. The static numerical simulations of passive magnetic bearings (PMBs) and analytical computation make the object of this paper.
