Abstract (2. Language): 
The magnetic bearing consists of levitating a shaft so that it is free to rotate about its axis. The magnetic bearing has the advantages of being very quiet work and very cleanliness because there is no mechanical friction or lubricants. The shaft has two permanent magnets attached to it. These two magnets determine a straight line rotation axis of the rotor shaft. The magnets are radially levitated and centered within a cavity by a passive permanent magnetic field in the adding stator housing assembly. The levitation and centering of the shaft axially is stabilized by a closed loop electronic servo circuit that regulates an electromagnetic field in the stator housing that pushes and pulls on the shaft magnets. The rotor weight can be between one gram and forty five thousand, four hundred grams. In 1985, the first magnetic bearing was developed that it had used to applications of gas turbines and other compressors. In these days, they can be used by many applications which are Medical, Transportation, Machine and Tools Industry, Aerospace, Vacuum and Clean room Environments... etc.

Abstract (Original Language): 
Manyetik yatak, mil ve ekseni etrafında boşlukta asılı kalarak serbest bir şekilde dönen bir yatak sistemidir. Hiçbir şekilde mekaniksel sürtünme ve yağlanmaya maruz kalmadıklarından dolayı, sessiz çalışma ve temizlik gibi birçok avantajlara sahiptirler. Yataklarda oluşan manyetik etkiler, sisteme eklenen stator tarafından sürekli olarak etki altına alınmakta ve bu sayede şaftın boşluk içersinde merkezde tutulması ve radyal olarak havada asılı kalması sağlanmaktadır. Statorun mili manyetik olarak çekme ve itmesi ile meydana gelen elektromanyetik alanın düzenlenmesini ve döngüyü sağlayan elektronik servo devresi kapalı konumdayken bile mil normal durumda eksenel olarak dengede tutulabilmektedir. Rotor ağırlıkları, 1-45400 gr. arasında olabilmektedir. 1985'de yapılan ilk manyetik yatak sadece gaz kompresörleri ve diğer kompresör türlerinde kullanılmaktaydı. Günümüzde ise tıp, ulaşım, makine takım endüstrisi, uzay sanayii, temizlik alanları vb. gibi birçok uygulama alanlarında kullanılmaktadır.
