  • Magnetically levitated and controlled body of revolution
    Patent number: 8461735
    Abstract: The invention relates to a body of revolution, in particular for a centrifugal, which comprises a rotator, an electric motor with a stator and a rotor wherein said latter is fixed to the rotator for rotational movement therewith, a support to which the stator of the electric motor is attached and a bearing unit for rotational arrangement of the rotor around an axis of rotation which comprises at least one bearing adapted to coact with an electromagnetic stabilizer unit in such a way that disturbing forces and/or disturbing vibrations of the rotator are counteracted and/or compensated.
