Abstract

The invention discloses a magnetic suspension control moment gyroscope high-speed rotor device. The device comprises a flywheel, three-degree-of-freedom integrated magnetic bearings, a high-speed motor, a gyroscope case, a protective bearing, a radial displacement sensor, an axial displacement sensor and an end cover, wherein a rotor component of the device is composed of the flywheel, a rotor part of the high-speed motor and rotor parts of the three-degree-of-freedom integrated magnetic bearings, a stator component is composed of the gyroscope case, a stator part of the high-speed motor, stator parts of the three-degree-of-freedom integrated magnetic bearings and the end cover, and high-speed rotation of a rotor is achieved between the rotor component and the stator component through thehigh-speed motor to provide angular momentum for output torque of a gyroscope. According to the device, through supporting by the two three-degree-of-freedom integrated magnetic bearings which are symmetrically arranged, radial and axial non-contact stable suspension of the rotor can be achieved, so that a magnetic bearing supporting system is compact in layout, the size and weight of the device are reduced, the axial length of the rotor can be shortened so that higher rotor inherent frequency and higher rotating speed can be obtained.

Description

technical field

[0001] The invention relates to the technical field of torque control gyroscopes, in particular to a high-speed rotor device for magnetic suspension control torque gyroscopes. Background technique

[0002] The control moment gyroscope has the characteristics of large output torque and high control precision, and is an ideal actuator for the attitude stability control of large spacecraft and the flexible attitude adjustment of small and medium-sized agile satellites. Due to the non-contact suspension support of the magnetic suspension bearing, it can overcome the friction and wear caused by the mechanical bearing, reduce the vibration and noise of the system, and does not need lubrication. The advantages of high reliability have obvious technical advantages compared with mechanical torque gyroscopes. In order to realize the stable driving of the high-inertia high-speed rotor around the main shaft, it is necessary to provide the rotation degree of freedom in o...
