MAGNETIC SUPPORT FOR UNIT Russian patent published in 1999 - IPC

FIELD: contactless supporting assemblies with electromagnetic bearings, applicable in creation of big transmission high-speed units, for instance, gas-transfer or gas-expansion units. SUBSTANCE: the shaft in the magnetic support has three rotors of transducers alternating with rotors of electromagnets; the radial transducers connected to the magnetic support control unit are conjugate to that of the transducer rotors, with which self-sustained vibrations in the magnetic support control system caused by shaft form bending are less than in the points of location of the two other transducer rotors. Besides, the transducer rotors have annular bulges, the transducers are conjugate respectively: the axial transducers to the lateral surfaces of the bulges, and the radial ones - to the rotor surface between the bulges. The body is built up for detachment in the radial plane located between the electromagnets; the axial electromagnets installed in the body part adjoining the unit body. EFFECT: reduced influence of the first forms of shaft flexural vibrations on operation of the magnetic suspension at variation of the shaft line dynamic parameters; improved operating characteristics of magnetic support associated with reduction of self-sustained vibrations in the magnetic support control system. 3 cl, 4 dwg
