永磁体磁力轴承在空调主机中的应用

摘要

介绍了永磁体磁力轴承的工作原理：将永磁体与其他部件组合，产生一个偏向磁悬浮合力，以克服水平转轴及其上所有附件的总重力，继而减少摩擦及能量损失、减振降噪、延长轴承寿命。针对空调主机常用的电动机与设备的两种连接方式，给出了具体的结构示意图。%Describes the working principle of permanent magnet shaft.The permanent magnet is combined with other parts to generate the deviated magnetic suspension composite force,so as to overcome the overall gravity of horizontal shaft and its attachments,to reduce the friction,energy loss,noise and vibration,and to extend shaft life.Considering the two common connection modes between motor and equipment for chillers of air conditioning system,presents the detailed structure charts.
