磁性轴承及其在电主轴中的应用

在２ＧＤＺ３０ＬＭ 型电主轴中，采用推力磁性轴承 滚动轴承混合型支承结构，其中磁性轴承承受轴向力（主载荷）。介绍了磁性轴承系统的组成及其性能指标，并对装有磁性轴承的电主轴的特点、试验情况作了简要说明。附图５ 幅。

In the 2GDZ30LM type electric spindles, the support structure com bined m agnetic thrust bearing w ith rolling bearing is adopted. The m agnetic bearing carries axial force (m ain load). The paper introduces the com position and property target of m agnetic bearing system , and m akes sim ply explaination for feature and test condition ofelectric spin- dle assem bled w ith m agnetic bearing.
