Problems solved by technology

The overall structure of the gyroscope adopts the traditional double-frame structure, and only the bearing support adopts a superconducting structure. The gyroscope with this overall structure is large in size, complex in structure, and difficult to assemble and debug. It is difficult to reduce its size by using micro-machining technology. Small, and to achieve mass production, cost reduction is difficult
This greatly limits its application range, especially in micro-satellites, micro-aircraft and other applications requiring small gyroscopes.

Abstract

A micro-gyroscope of permanent magnet rotor stably suspended by high temperature superconductor is prepared by setting gyroscope bottom shell on piqued nitrogen Dewar through support column; forming top and bottom stators of gyroscope by high temperature superconductor, silicon nitride insulation material and stator driving detection moment layer; forming gyroscope rotor by two layers of rotor driving detection moment layer, two layers of cylindrical silicon nitride insulation material and cylindrical permanent magnet material .

Description

technical field [0001] The invention relates to a device in the technical field of micro-electromechanical systems, in particular to a micro-gyroscope with a high-temperature superconducting stabilized suspension permanent magnet rotor. Background technique [0002] The suspended rotor micro-gyroscope does not require mechanical support, and integrates the high precision of traditional gyroscopes with the characteristics of small size and low cost of micro-mechanical technology. Non-contact suspension support is an important guarantee for the work of suspended rotor micro-gyroscopes. At present, suspended rotor micro-gyroscopes mainly use electromagnetic and electrostatic forces to achieve suspension support. [0003] After searching the literature of the prior art, it was found that the Japanese patent JP1193612 describes a micro-gyroscope made of superconductors. The core structural feature of the gyroscope is that the rotor is attached to two superconductors, and the two ...
