摘  要

磁悬浮技术是将电磁学、机械学、动力学、电子技术、自动控制技术、传感技术、检测技术和计算机科学等高新技术有机结合在一起，成为典型的机电一体化技术。磁悬浮技术是利用磁场力使一物体沿着或绕着某一基准框架的一轴或者几轴保持固定位置，由于悬浮体和支撑之间无任何接触，克服了由摩擦带来的能量消耗和速度限制，具有寿命长，能耗低，安全可靠等优点。目前，各国已广泛开展了对磁悬浮控制系统的研究随着控制理论的不断完善和发展，采用先进的控制方法对磁悬浮系统进行的控制和设计，使系统具有更好的鲁棒性。在我国，磁悬浮技术研究起步较晚，水平相对落后。
随着电子技术的发展，特别是电子计算机的发展，带来了磁悬浮控制系统向智能化方向的快速发展。近年来，磁悬浮技术开始由宇航、军事等领域向一般工业应用方面发展，广泛应用于很多领域，如：磁悬浮列车、磁悬浮隔振器、磁悬浮轴承、高速机床进给平台、磁悬浮硬盘、飞轮电池等。
    本文主要针对磁悬浮技术对一种磁悬浮主轴进行探索与研究.

Abstract
The magnetic suspension technique is the electromagnetics, mechanics, dynamics, electronic technology, automatic control technology, sensor technology, detection technology and computer science and high technology are organically combined together, become a typical electromechanical integration technology. The magnetic suspension technique is the use of magnetic field makes an object along or around a reference frame of a shaft or shaft to maintain a fixed position, due to suspension and support between without any contact, overcome by the friction caused by energy consumption and the speed limit, has long service life, low energy consumption, safe and reliable advantages. At present, all countries have been widely carried out in the research on magnetic suspension control system with the control theory of continuous improvement and development, the use of advanced control method for maglev system control and design, the system has better robustness. In our country, magnetic levitation technology research started late, the level is relatively backward.
With the development of electronic technology, especially the development of the electronic computer, brings a magnetic levitation control system intelligent direction of the rapid development of. In recent years, magnetic levitation technology started by the aerospace, military and other fields to the general industrial applications development, widely used in many fields, such as: maglev, maglev isolator, magnetic bearings, high-speed machine tool feeding platform, hard disk, the flywheel battery.
This article mainly aims at the magnetic suspension technology of a kind of magnetic suspension spindle to explore and research.
