Dynamic stiffnesses of active magnetic thrust bearing including eddy-current effects

Y Sun, YS Ho, L Yu - IEEE Transactions on Magnetics, 2009 - ieeexplore.ieee.org
The eddy currents induced in a thrust bearing result not only in a power loss of the system
but also in phase lag and a decrease in magnitude of the magnetic force. Therefore, an …

Dynamic factor models of a thrust magnetic bearing with permanent magnet bias and subsidiary air gap

B Han, S Zheng, X Hu - IEEE Transactions on Magnetics, 2012 - ieeexplore.ieee.org
A hybrid thrust magnetic bearing (HTMB) with permanent magnet creating bias flux is used
to save energy. The eddy currents have a fundamental impact on the dynamic …
