Magnetic bearings, is not very common on the market today. Today, I gave you to introduce the two most common magnetic FAG bearings.ball bearing companies
A. FAG permanent magnet-type magnetic bearing permanent magnet-type magnetic bearing is made by the permanent magnet can be made into various shapes. FAG bearing load capacity and stiffness is determined by the type of permanent magnet materials, magnetic pole shape, size, thickness and configuration, the bearing clearance, as well as the size of the soft magnet part. This theoretical calculation of the FAG bearing is very difficult, and often experiment similar to the method for structural design. Experimental methods to determine the structure of several typical bearing, measured its carrying capacity, stiffness values. New design FAG bearings to take the same material, structure and size in proportion to determine its performance can be calculated by proportion, such as carrying capacity and bearing the characteristic dimension proportional to the square. Experience has shown that increasing the magnet thickness and the use of soft magnet pole piece structure is e ffective to improve the bearing carrying capacity. Of particular note is that the permanent magnet bearing to take no matter what kind of permanent magnet materials and structural forms, has a maximum size limit, exceed the size, the bearing can not support its own weight. Therefore, the permanent magnet bearing can not be designed too large.double row ball bearing
Two. Passive ac excitation of magnetic bearings (1) thrust bearings thrust bearings are usually paired modular, each bearing an electromagnet. The core geometry is generally E-shaped, U-shaped or annular. Tuning points series and parallel connection of two kinds.double row angular bearing
