电磁轴承技术是国际上20世纪60年代中期开始研究的一项新的支承技术。第一部分简要介绍电磁轴承的结构、原理、特点，并分析了国内外电磁轴承的发展现状及前景。第二部分，以乙烯装置的甲烷膨胀/压缩机为例，阐述了电磁轴承设计选型时的注意事项及其应用。
電磁軸承技術是國際上20世紀60年代中期開始研究的一項新的支承技術。第一部分簡要介紹電磁軸承的結構、原理、特點，併分析瞭國內外電磁軸承的髮展現狀及前景。第二部分，以乙烯裝置的甲烷膨脹/壓縮機為例，闡述瞭電磁軸承設計選型時的註意事項及其應用。
전자축승기술시국제상20세기60년대중기개시연구적일항신적지승기술。제일부분간요개소전자축승적결구、원리、특점，병분석료국내외전자축승적발전현상급전경。제이부분，이을희장치적갑완팽창/압축궤위례，천술료전자축승설계선형시적주의사항급기응용。
The active magnetic bearing is a new supporting technology in the world,and it began to be study in the mid- 1960s.In the paper, the structure,principle,characteristics of active magetic bearings were introduced,and the developing level and tendency of the active magnetic bearing were analyzed. At last, taking methane expansion compressor in the ethylene plant as an example, matters needing attention during design,type selection and application of the active magetic bearing were discussed.
