A centrifuge for separating gaseous constituents of different masses consists of: a vertical tubular rotor; means for introducing a gas mixture of different masses into the rotor and means for removing at least one of the gas components from the rotor; a first bearing means supporing the rotor at one end; a support; a damping bearing mounted on the support; a shaft fixed to the rotor at the opposite end and mechanically connecting the rotor to the damping bearing; a cup-shaped tube of electrically conductive, non-magnetic material in coaxial relationship with the shaft, the open end of the tube extending away from the rotor, and the closed end of the tube being directly secured to the adjacent end of the rotor; an annular core of magnetic material fixedly mounted on the support so as to be disposed within the tube and around the shaft; and a second annular magnetic core with coils to receive polyphase current to produce a rotating magnetic field traversing the circumference of the tube, fixedly mounted on the support so as to surround the tube, the size of first and the second annular core being such as to permit limited radial displacement of the shaft and the tube.
