摘要： A device for reducing the vibrations of a rotating machine equipped with an active magnetic suspension comprises at least two vibration detectors located on the machine frame for detecting disturbances applied to the frame, and at least an additional selection feedback loop with narrow band and high gain whose central frequency is synchronized with a reference frequency and which receives signals delivered by the vibration detectors. The additional selective feedback loop comprises means for integrating the signals delivered by the vibration detectors and filtering means for eliminating the transient signals whose frequency is not linked to the reference frequency.

摘要： The device for magnetically suspending a rotor relative to a structure comprises at least one axial active magnetic bearing with a main electromagnet coil disposed in a stator and having load-bearing surfaces placed facing an armature extending essentially perpendicularly to the axis of the rotor. A device for detecting the axial position of the rotor is associated with circuits for servo-controlling the current carried by the main electromagnet coil. A compensation coil is disposed close to the main electromagnet coil, but in a position that is situated away from the load-bearing surfaces of the stator that co-operate with the rotor armature. The compensation coil is connected in series with the main electromagnet coil, but carries current in the opposite direction to that carried by said main electromagnet coil. The device constitutes an axial abutment of optimized capacity without magnetic leakage.

摘要： The flexibly-mounted turbomolecular pump comprises a leaktight casing mounted on a structure via a mechanical damper, a vertical support driven by an electric motor, radial magnetic bearings, an axial magnetic bearing, radial detectors, an axial detector, an emergency mechanical bearing, and a control module comprising power supply circuits and servo-control circuits for the axial and radial magnetic bearings. The servo-control circuits present low stiffness and include filter circuits for defining a limited passband. The control module comprises a comparator unit for detecting abnormally large movements of the rotor from signals delivered by the axial and radial detectors, which movements are greater than predetermined thresholds. The servo-control circuits include a restabilization network and a unit for selectively activating the restabilization network during a predetermined duration after a time at which the crossing of at least one of the predetermined thresholds is detected during a movement of the rotor.
