Abstract
A device for insulating a body on magnetic bearings from vibration of its stator and hence the environment and vice versa. The body may include a rotor which can produce undesirable vibrations during rotation. The position of the body is caused to follow slow movements of the stator, but does not follow higher frequency interference. However, intentional fast position regulating procedures are possible. The device includes a double integrator which generates a largely interference-free position sensor signal for low vibration bearing adjustment which is followed slowly by a true position sensor signal. The device can be used in a flywheel for satellite stabilization where it facilitates adjustment of the angular position while at the same time providing insulation against vibration.
