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 …
