1)Be allowed to achieve high rotor speed. By magnetic bearings in the rotor can be supercritical, hundreds of thousands per minute to the running conditions, the rotation speed only restricted by the intensity of rotor material. Usually in the same journal diameter, the rotor magnetic bearings are able to reach a speed about2 times higher than roller bearings and about three times higher than journal bearings. Germany obtained through tests: Rolling bearings, plain bearings, magnetic bearings.
(2)Small friction power. In the 10000 rpm, magnetic bearings power dissipation only about hydrodynamic lubrication of the journal bearings' 6%, only 17% of rolling bearings, which are of important significance of energy conservation. First, the magnetic bearings have small energy consumption, saving energy; In addition, magnetic bearing no oil, and saving oil resources.
(3)Low maintaining cost, long life. The magnetic bearing is to rely on magnetic suspension Journal, the relative movement between the surface there will be no contact, and there is no friction, wear and contact fatigue life of the issue, and the reliability of electronic components in the rated working conditions, much higher than the mechanical components, magnetic bearing life and reliability are much higher than in conventional type of bearings.
(4)Magnetic bearings without lubrication, thus there is no lubricant on the pollution of the environment. In a vacuum, radiation and prohibit the lubricant applications, such as vacuum technology, ultra-clean and sterile room or very pure media and so on, magnetic bearings have incomparable advantages. In general applications, because of eliminating the lubricant storage, filtration, cooling, recycling facilities, in the price and space occupied, it is entirely possible to compete with and plain bearings.
(5)Magnetic Bearing system is flexible adjustment of stiffness and damping, and able to safely beyond the rotor critical speeds. In industrial applications, magnetic bearing not only for aerospace sector, the nuclear industry, but also been rapidly applied to the military sector and the industrial sector based on the hundreds of different types of rotary or reciprocating machinery. Such as Stirling refrigerator (IR night vision), thermal Turbine (submarine), Stirling heat pump, high-speed grinder, high-speed milling machinery, high-speed lathes, high-speed motor, centrifuges, turbine compressors, vacuum pumps, achieved by the scope of the technical indicators:
(1)Speed: 0 ~ 8 x100000rpm
(2)Diameter: 14 ~ 600 mm
(3)Single bearing capacity: 0.3 ~ 5 x 10000N
(4)The use of temperature range: -253 0C ~ 450 0C
(5)Stiffness: 100000 ~ 100 million N / m
