SUPERCONDUCTION MAGNETIC BEARING

摘要

PROBLEM TO BE SOLVED: To improve rigidity, which a superconduction magnetic bearing possess and stability against a load change. SOLUTION: A superconduction magnetic bearing comprises a superconduction magnetic bearing 1 provided on a linear stage 3 with a superconductor 2; a floating body 4 formed such that a rotary shaft 8 supported by a radial gas bearing 9 is attached to a magnet 5 above the super conduction magnetic bearing 1; a sensor 15 to defect a displacement amount by a load W exerted on the floating substance 4: and a control means 17 to control the position of the linear stage by raising and lowering the linear stage 3 according to a displacement amount detected by the sensor 15.
