The object of the invention is a device for insulating a body on magnetic bearings from the vibration of its stator and hence the environment and vice versa. It may especially concern a rotor (3) which can produce undesirable vibrations through its rotation.The proposed invention ensures that the position of the body follows slow movements of the stator but higher-frequency interference is not transmitted. At the same time, however, fast intentional position regulating procedures are possible. The essential element of the invention is a double integrator (15) which generates a largely interference-free position sensor signal for low-vibration bearing adjustment which is slowly followed by the true position sensor signal. The invention is especially useful in a flywheel for satellite stabilisation where it facilitates adjustment of the angular position while at the same time providing insulation against vibration. |
