The technology of the Active Magnetic Bearing is developed so fast that it can be utilized in many field.In order to reduce the size of the magnetic bearing to fit the artificial heart,magnetic suspended hard disk,gyroscope and etc,a new minitype Magnetic Bearing-Rotor system is successfully designed by improving the mechanical structure and control technique of the bearing.It also can suspend stably.Experiments have already proved that this design can not only effectively reduce the size of bearing but also simplify the structure of bearing.
1 Introduction
Traditional Active Magnetic Bearings (AMBs) usuall have two radial bearings and a thrust bearing to control five degrees of freedom actively [1].The size of AMBs is difficult to be reduced to a scale in order to be applied.So the number of bearings and sensors are optimized to reduce the size of the AMBs.Considering the related design experience [2-3],Only two groups of AMBs are adopted as the support to actively control two degrees of freedom inside a single plane,which is named as the main control plane.The other three degrees of freedom of the rotor suspended passively,whose support is offered by the component forces of two groups of bearings inside the main control plane.Its principle is demonstrated in Fig.1.
Plane x-y is the main control plane.In this plane,the bearing is stabilized in its balance place by active control.One degree of freedom turning around z axes
is controlled by electric machine .The other three degrees of freedom which include translating around z axes,turning around x axes and y axes are passively stabilized by the component forces of bearings inside the main control plane.Its principle is demonstrated in Fig.2.when the rotor departures from the main control plane,bearing force will make component force which is contrary to the direction of
displacement to pull the rotor back to realize the stable suspensions in these three degrees of freedom.

活跃有磁性的举止的技术如此快速地被发展,因而它能在许多领域中被利用.为了要减少有磁性举止的大小适合人造的心、有磁性的中止硬盘,回旋装置而且及其他,新的 minitype 有磁性的举止-转子的系统成功地藉由改良机械的结构被设计而且控制举止的技术.它也能坚固地中止.实验已经证明这设计能不只有效地减少生的大小也单一化举止的结构了.
1 介绍
传统的活跃有磁性的举止 (AMBs) usuall 有生积极地控制自由的五度 [1] 的二光线的举止和推进.AMBs 的大小难以被转为刻度为了要是应用.因此举止的数字和感应器被最佳化减少 AMBs 的大小.考虑相关的设计经历 [2-3] ,只有二群 AMBs 当做支持被采用在平内积极地控制自由的二度,当做主要的控制被命名平的.转子的自由的另一个三度消极地中止,支持从二群举止的成份军队得到进主要的控制飞机.它的原则在图 1 被示范.
飞机 x-y 是主要的控制飞机.在这一个飞机中,举止在活跃控制旁边的它的平衡地方中被稳定.在 z 周围的自由旋转的一度轴
被电机器控制.包括的自由的另一个三度在 z 轴的周围翻译,在 x 轴周围的旋转和 y 轴消极地在主要的控制飞机内被举止的成份军队稳定.它的原则在图 2 被示范.当来自主要部份的转子离开控制飞机的时候,生力量将会使成份强迫哪一个是和方向相反
把转子拉回到的换置在自由的这三度中了解稳定的中止.
