磁悬浮轴承应用发展及关键技术综述

Study on Key Technologies and Applications of Magnetic Bearings

磁悬浮轴承是利用磁场力将转子悬浮于空间,实现定子和转子之间没有机械接触的一种新型支承轴承,在航空航天、机械工业及生命科学等领域具有非常广阔的应用前景。本文首先详细综述了国内外磁悬浮轴承的应用发展状况,归纳了国内外磁悬浮轴承的定义,针对磁悬浮轴承的结构(有传感器磁悬浮轴承、无传感器磁悬浮轴承)和磁悬浮轴承的悬浮力建模方法(有传感器磁悬浮轴承的建模方法和无传感器磁悬浮轴承的建模方法)进行了阐述。

A magnetic bearing is a new support bearing, which can suspend a rotor in the space by magnetic forces without machinery contact between the rotor and the stator. So a magnetic bearing has a vast application prospect in the fields of aeronautics and astronautics, mechanical industry, life sciences and so on. In this paper, firstly, the application and development at home and abroad are reviewed. Then the definitions for magnetic bearings are summarized. Finally, the structure types(magnetic bearings with sensors and sensorless magnetic bearings) and modeling approaches on suspension forces(modeling methods based on magnetic bearings with sensors and sensorless magnetic bearings) are systemically expounded.
