A MOVEABLE MAGNETIC SUSPENSION DEVICE

摘要

A movable magnetic suspension device comprises a rack box body, and a floater below the rack box body with a permanent magnet. The permanent magnet is located on the gravity line of the floater. An electromagnet interacting with the permanent magnet of the floater, a displacement sensor for measuring the floater position and a magnetic suspension control circuit are provided on the rack box body. An input terminal of the magnetic suspension control circuit is connected to the displacement sensor, and an output terminal thereof is connected to a coil of the electromagnet. The electromagnet and the displacement sensor are provided on a movable device on the rack box body. Thus, the floater can move with the movable device while the floater self-rotates.
