Problems solved by technology

[0003] After searching the literature of the prior art, edited by Lin Shier, etc., "Power Tuning Gyroscope" published by National Defense Industry Press, pages 176-190, the power tuning gyroscope involved in this article has a large size and is driven by a hysteresis motor. The parts are nested with each other, and the overall structure is complex
Due to the use of traditional processing and assembly technology, the size is larger and the weight is increased. For occasions that require small size, light weight, and low cost, it is not applicable

Abstract

A micro-gyroscope of flexible rotor tuned by electromagnetic driving force is prepared by setting top rotor and bottom rotor at top and bottom of shell, setting one jewel bearing at center hole of top rotor, setting another at center hole of bottom rotor, placing shaft on both bearings and driving rotor on shaft between top and bottom rotors, setting gyroscope rotor on shaft above top rotor. The prepared micro-gyroscope can be used as orientational gyroscope.

Description

technical field [0001] The invention relates to a micro-gyroscope in the technical field of micro-electro-mechanical systems, in particular to a micro-gyroscope with an electromagnetically driven power-tuned flexible rotor. Background technique [0002] The flexible gyroscope is a high-performance, low-cost and high-precision gyroscope. It uses a flexible support to take over the traditional suspension technology and brings a series of advantages, so it is widely used in inertial navigation systems. According to the specific form of flexible support and the method of compensating the elastic moment, the flexible gyroscope can be divided into two types: thin neck type and dynamic tuning type. The neck-type flexible gyroscope started to be manufactured earlier, but before it was put into mass production, a more novel power-tuned flexible gyroscope appeared. At present, the thin-neck flexible gyroscope with medium precision is still in use, and the precision is also improving ...
