Passive eddy-current damping as a means of vibration control in cryogenic turbomachinery [PDF]

Lateral shaft vibrations produced by a rotating unbalance weight were damped by means of eddy currents generated in copper conductors that were precessing cyclicly in the gap formed by the pole faces of C-shaped, permanent magnets.
