Abstract

PURPOSE:To control and excessive vibration of a rotary object so that its rotational speed can be shifted in a higher speed range over the critical speed, by forcing a vibration suppressor wheel to touch the rotary object set on a thrust magnetic bearing when its rotational speed reaches a certain specific level. CONSTITUTION:When any abnormal vibration is generated to a rotary object 4, and the output from a rotational speed detector 12 increases beyond the level which is set in a standard voltage source 14, a comparator 13 shall be set in ON status, causing the current source 15 to supply a solenoid 16 with a current. Accordingly, the solenoid 16 forces a wheel fixing frame 18 to touch the face of groove 11 provided on the periphery of the rotary object 4 so as to suppress any excessive vibration of the rotary object 4 during its rotational motion.
