Estimating the term…
Method and apparatus for positioning and altitude-stabilizing an inert mass slewable on a movable base in at least one axis are disclosed. Oppositely rotatable driving parts are supported on either the base or the mass, and the driven parts on the other of the base or mass are friction coupled to the driving parts under the control of one or more control devices. The control devices are controllable electromagnetic clutches or brakes, and control of the magnetic field is achieved by the hyperexcitation through feedback and intensification of the measured magnetic field strength and/or the control torque.
Device for positioning and attitude-stabilizing a slewable inert mass supported on a base, said device having at least two oppositely-directed rotatable driving parts supported on one of the base and the inert mass by means of at least one control device regulated in friction contact with compressible driven parts, said driven parts being supported on the other of the mass and base, said control device having at least one electromagnetic clutch or brake in which the magnetic field is controlled by hyperexcitation of the exciting coil through feedback and intensification of the measured magnetic field strength.
