Problems solved by technology

The existing single-frame control moment gyroscope, the gyroscope rotor system and the frame system are all supported by mechanical bearings. Due to the wear of the mechanical bearings, there are still many restrictions on the speed and service life of the rotor system. At the same time, due to the friction torque of the mechanical shaft of the frame system It is non-linear, which will bring a disturbance torque to the spacecraft system, thereby affecting the stability of the spacecraft; the e

Abstract

A fully non-contact single-frame magnetic- levitation torque-controlling gyro is composed of magnetically levitated frame system and magnetically levitated rotor system. Said magnetically levitated frame system consists of frame jointer, protecting bearing, mandrel, torque motor, angular position sensor, radial and axial magnetic bearings, integrated radial/axial displacement sensor, electrically conductive slide ring and base. Said magnetically levitated rotor system comprises gyro rotor, axle holder, axial and radial magnetic bearings, integrated radial/axial displacement sensor, protecting bearing, drive motor, sealing cover, base and jointer.

Description

technical field [0001] The invention relates to a completely non-contact single-frame magnetic levitation control moment gyroscope, which can be used for attitude control of large spacecraft such as space stations or small spacecraft such as agile maneuvering satellites. Background technique [0002] Modern satellite platforms or small spacecraft used in earth observation or scientific research have higher and higher requirements for stability and flexibility of maneuvering at large angles. Satellites that can maneuver at large angles can improve the efficiency and quality of Earth observation. The single-frame control moment gyro is one of the main actuators used for attitude control of spacecraft. The existing single-frame control moment gyroscope, the gyroscope rotor system and the frame system are all supported by mechanical bearings. Due to the wear of the mechanical bearings, there are still many restrictions on the speed and service life of the rotor system. At the s...
