FIELD: centrifugal apparatus for carrying-out physical or chemical processes. ^ SUBSTANCE: ultracentrifuge comprises structural frame, solenoid for the magnetic suspension provided with rod ferromagnetic core, and winding of the electric motor secured to the intermediate section of the structural frame. The inner port in the frame receives unmovable vacuum vessel. The ferromagnetic rotor is freely suspended inside the vacuum vessel. The bottom section of the frame is provided with the displacement pickup whose output is connected with the output of the solenoid of magnetic suspension through the device for control of the current in the solenoid of the magnetic suspension, sleeve with viscose fluid, and steel needle with float arranged inside the sleeve. The sleeve is secured to the frame. The rotor is hollow, filled with fluid, and provided with remote output valve in the bottom section. ^ EFFECT: enhanced maximum speed of rotation. ^ 1 dwg |
