Abstract

The invention discloses an internal rotor magnetic suspension spherical surface gyro flywheel. The flywheel comprises a stationary part and a rotating part. The stationary part comprises an upper gyro chamber, a middle gyro chamber, a lower gyro chamber, a sealing ring, an axial spherical surface magnetic bearing stator, a protective bearing, a motor assembly stator, an axial displacement sensor assembly, a radial displacement sensor assembly, a radial spherical surface magnetic bearing stator and a Lorentz force magnetic bearing stator. The rotating part comprises a gyro outer rotating disk assembly, a gyro inner rotating shaft, sphere center adjusting backing rings and gyro rotor lock nuts. A spherical surface magnetic bearing is adopted to serve as supporting member, five-degree-of-freedom active suspension of the magnetic suspension gyro flywheel can be achieved, the interference of three times of translation control of a rotor in two times of radial twist control is eliminated, and then the moment precision of the high gyro moment instantly output by the gyro flywheel is increased.

Description

technical field [0001] The invention relates to an inertia actuator that can be used as an attitude control system of an agile mobile satellite platform, in particular to an inner rotor magnetic levitation spherical gyro flywheel. Background technique [0002] Because the momentum exchange system can provide high attitude control accuracy, it is widely used in the attitude control system of spacecraft such as satellites and probes. The flywheel system changes the magnitude of the angular momentum by controlling the rotor speed to generate the required control torque, thereby precisely controlling the attitude of the spacecraft. Increasing the rotational speed can increase the output torque range of the flywheel, but as the rotational speed increases, the life of the flywheel system supported by traditional mechanical bearings will be affected. At the same time, due to the friction of mechanical bearings, the rotor speed cannot be very high. To increase the angular momentum ...
