Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to an integrated explosion-proof magnetic levitation bearing control device. Background Technology

[0002] Bearings are an important component in mechanical equipment. Their main function is to support the rotating shaft, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. Bearings consist of two sets of coaxial ring structures, with the inner and outer rings fixedly connected to the rotating shaft and bearing housing, respectively.

[0003] Magnetic levitation bearings use magnetic force to levitate the rotor in the air, eliminating mechanical contact between the shaft and the external stator. The principle is that the magnetic induction lines are perpendicular to the magnetic levitation lines, and the shaft is parallel to the magnetic levitation lines. Therefore, the rotor's weight is fixed on the running track. The almost unloaded shaft pushes against the magnetic levitation lines, creating a suspended rotor on the fixed running track.

[0004] A rotating shaft equipped with a magnetic levitation bearing needs to maintain a stable relative position at all times to prevent radial and axial offsets. The current in the control coil is adjusted based on the acquired position signal to change the magnetic flux. Due to explosion-proof requirements in production sites, the control unit is typically located in a control room, making the transmission cables susceptible to interference and causing drift in feedback and control signals.
