METHOD OF ORIENTING ROTOR SHAFT OF REVOLUTION BODY WITH MAGNETIC SUSPENSION SYSTEM PASSIVE IN RADIAL DIRECTION AND ACTIVE IN AXIAL DIRECTION

摘要

P process and device which makes it possible to achieve balancing of the rotating bodies to a passive magnetic suspension, the radial and axial active and to orient the axis of rotation. / p & & p & is provided at the axial ends of the body 1, two centering members on the side of the rotor 2, 3 made of magnetic rings centered and offset with respect to the two centering devices on the stator 4, 5 to magnetic rings centered and offset, the magnetic field in the air gaps 8, 9 between the pairs of rings being rendered variable as a function of the received signals of sensors of correction of the shafts 34, 35 and 36, 37, 38, 39. The present invention can be used in all cases, the balancing of a magnetically suspended body, and in particular in applications to ultracentrifugation, to the flywheel, to seismographs. / p
