GEAR FOR SUSPENSION OF FERROMAGNETIC SPHERICAL ROTOR Russian patent published in 2000 - IPC

FIELD: instrumentation, non-contact gyroscopes, accelerometers, magnetic bearings. SUBSTANCE: gear has two stators with eight slots which house eight concentrated windings. Four alternating windings of each stator are interconnected in parallel or in series and form first and second tractive electromagnets placed diametrically opposite along symmetry axis of stators. Each two adjacent windings from the rest of correspondingly first and second stators are connected in parallel or in series and form four tractive electromagnets placed along two orthogonal axes and along symmetry axis of stators. Sources of current are connected to terminals of six tractive electromagnets. Simplified design of suspension, decreased number of sources of controlled current provide for possibility of insertion of proportional-plus-integral elements to reduce sagging of rotor and for adjustment of rigidity along three mutually orthogonal axes of suspension. EFFECT: adjustment of rigidity along three mutually orthogonal axes of suspension. 6 dwg
