Dynamics of active magnetic thrust-bearings.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990
A linearlized model considering the effect of eddy currents is shown to be useful for the analysis of the dynamics of active magnetic thrust-bearings, in which electromagnet cores are composed of solid steel. The dynamics of a magnetic control-force is modeled by the first-order time-lag system with unknown parameters : a gain and a time constant.
