METHOD AND DEVICE FOR BALANCING ROTARY BODIES WITH PASSIVE RADIAL AND ACTIVE AXIAL MAGNETIC SUSPENSION AND FOR ORIENTING THEIR AXIS OF ROTATION

摘要

A method and device for balancing magnetically suspended bodies wherein at the axial ends of the bodies are included two centering devices on the rotor side constituted by centered and excentric magnetic rings facing two centering devices on the stator side with centered and excentric magnetic rings, the magnetic field in the air gaps between the pairs of rings being made variable according to signals received from correction sensors of the axes and of the alignment. The invention can be used in all cases of balancing a magnetically suspended body and notably in applications to ultracentrifugation and to momentum wheels.
