MAGNETIC SUSPENSION OF THE DEVICE ROTOR Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: magnetic suspension of the device rotor has radial and axial electromagnetic supports and units of the axial and radial position pickups of the rotor, with all this being placed in the cylindrical housing. A dismountable flange for fixating the axial position of the insurance bearing mounted inside the flange is fixed on the housing. The axial support is made as two stators with control windings, with one of them being fastened on the inner side of the housing and the other on the device, and a rotor made as a disk mounted between them with a gap. The radial support is made as a stator fastened on the housing and a rotor mounted on the device rotor, with both being coaxially mounted. One part of the pickups of the radial and axial positions of the device rotor is set up on a common member fixed on the inner wall of the housing. The other part interconnecting with them is also set up on a common member made as a bush with a bead disposed on the device rotor. The flange is made with through holes for the access to the position pickups during their regulation. EFFECT: quicker disassembly and assembly of the suspension for replacing the disabled members and the required regulation without its disassembly. 1 dwg
