Four freedom degree single frame magnetic suspension control torque gyroscope
A four freedom degree single frame magnetic suspension control torque gyroscope can serve as a gesture control execution mechanism of a large satellite, an earth observation platform, a space station and other large spacecrafts and is composed of a four freedom degree magnetic bearing, a high speed motor, a radial and axial integrated sensor, a radial sensor, an upper protective bearing, a lower protective bearing, a central spindle, a wheel body, a base, an upper sensor detection ring, a lower sensor detection ring, a shell, frame central spindles, a frame motor, a frame, mechanical bearings, an angle position sensor and an electric conduction sliding ring. The driving part of the four freedom degree magnetic bearing controls a gyroscope rotor to move in a translational mode and deflect, and the gyroscope rotor moves in a translational mode in the axial direction through the driven part of the four freedom degree magnetic bearing. All the components are compact in layout, the size and the weight are reduced, noise of a system is lowered, the size and the weight of the system are reduced, bearing friction force is eliminated, then the service life of the single frame control torque gyroscope is prolonged, and the control precision of the single frame control torque gyroscope is improved.
