Abstract

The invention discloses a magnetically suspended gyroscope adopting the magnetic path decoupling design. The magnetically suspended gyroscope consists of a stator system and a rotor system, wherein the stator system mainly comprises a mandrel, a base, a protective bearing, a radial magnetic bearing stator, an axial magnetic bearing stator, a motor stator, a deflection magnetic bearing stator and a displacement sensor; the rotor system mainly comprises a flywheel body, a protective bearing cover, a radial magnetic bearing rotor, an axial magnetic bearing rotor, a motor rotor and a deflection magnetic bearing rotor. According to the magnetically suspended gyroscope, a magnetic bearing supporting technology is adopted, frictional wear caused by a mechanical bearing is avoided, and a magnetic path decoupling path of each channel of the magnetic bearing is adopted to eliminate disturbance torques of three translation controls of magnetic bearings to radial two deflection controls, so that sensing precision of the gyroscope is improved.
