VERTICAL ROTOR MAGNETIC SUPPORTING NIT Russian patent published in 2005 - IPC

FIELD: upper magnetic supports of high-revolution rotors with vertical rotation axis for holding rotors in vertical position, for example rotors of energy accumulator, centrifuges, gyroscopes and similar devices.

SUBSTANCE: supporting unit includes ferromagnetic ring mounted on upper end of magnet of magnetic support of rotor and having thickness equal to 1.2 - 1.5 of mean diameter of magnet. Non-magnetic gasket may be placed between magnet and ferromagnetic ring. Thickness of gasket is equal to thickness half of ferromagnetic ring.

EFFECT: lowered pressure acting upon lower support, reduced mass and size of magnetic support especially in axial direction, increased working length of rotor.
