ABSTRACT:
A magnetic suspension device for inertial wheel or rotary body holds a rotor coaxially with respect to a stator while being mechanically free. On the stator side it comprises an inner continuous ferromagnetic crown and an outer discrete ferromagnetic crown formed with a plurality of diametrically opposite sectors provided with coils. Between said crowns there is interposed an axially magnetized crown carried on the rotor and clamped between two annular flanges. Said coils provide for radial centering of the rotor whereas the magnetized crown provides for axial centering thereof. The association of the crowns and the sectors ensures minimum path for the induction lines. The magnetic suspension device is intended for space or terrestrial applications especially for satellites, telecommunications, vacuum pumps, printing cylinders, machine-tools, optical scanning systems and the like.
