Problems solved by technology

This single-stator electromagnetic levitation microsystem has the following disadvantages: 1. Because it can only be driven by unilateral levitation, the levitation stability of the whole device is not good, and the stable levitation anti-interference is poor; 2. With the increase of the current in the levitation coil Large, the suspension height of the micro-rotor increases, so the lateral stiffness of the suspension is not adjustable; 3. A special limit device is required so that the micro-rotor can stay near the center of the stator when it is not working, so that it can be restarted next time. start up
This speed is far from meeting the requirements of high-precision micro-gyro

Abstract

A type of stator embedded electromagnetism suspending Microsystems of microcomputer electric system technology field includes round box type micro suspending quality, upper stator, middle base, down stator, leading line, middle column, lower base. The upper stator and the lower stator are similar completely, they includes stable suspending loop outer loop, stable suspending loop inner loop, connecting line. The round box type micro suspending quality is suspended stably at the outer edge of the middle base under the function of electromagnetic force of upper stator and lower stator. The stator embedded electromagnetism suspending Microsystems adopts the round box type micro suspending quality and stator embedded structure, the structure can increase the suspending rigidity and side stability rigidity of micro suspending quality, at the same time the middle base can limit the position when the round box type micro suspending quality does not work, it fits for application in field of micro peg-top, micro inertia measuring unit, and resolves the defects of background technology.

Description

technical field [0001] The invention relates to a device in the technical field of micro-electromechanical systems, in particular to a stator-embedded electromagnetic levitation microsystem. Background technique [0002] The use of suspension technology can avoid the friction and wear caused by contact, so as to obtain high moving speed or rotation speed, and at the same time avoid the pollution of materials due to contact, so suspension technology is widely used in production or life, such as Maglev trains, electrostatic levitation bearings, electromagnetic levitation smelting technology, electrostatic gyroscopes, etc. Electromagnetic levitation is completely a passive levitation technology, that is, it does not need an external feedback control circuit to achieve autonomous levitation. At the same time, electromagnetic levitation has no strict requirements on the gap between electrodes. Compared with electrostatic levitation, the structure of electromagnetic levitation dev...
