Electromagnetic bearings for shaft and bearing no direct contact, without lubrication, can work in a vacuum and in a wide temperature range, the friction is small, without speed limits (some up to 23 million rev / min speed, line speed up to 3 times the speed of sound), long life, the structure can be diverse. Static bea ring requires a lot of electric field strength, the application is limited, only a few meters. Magnetic bearings have greater carrying capacity and rigidity, have been used for ultra-high-speed trains, super-high-speed centrifuge, turbine generator, the angular momentum of the space vehicle flywheels, flow meters, density meters, power meter, vacuum pump, precision steady flow device and gyroscopes. With the development of magnetic materials and electronic technologies, the application of electromagnetic bearings is growing.angular bearings
Electric force and electric field strength, electric displacement and the electrode area is proportional to the magnetic field strength and magnetic field strength, magnetic flux density and the magnetic pole is proportional to the area. abec 7 bearings
Appropriate choice of electric or magne tic field parameters and geometry, available to the bearing load capacity and stiffness. Is inversely proportional to the square of the distance between the electrostatic suction or magnetic attraction, and the object, according to Yasuji Hugh Theorem statics system is statically indeterminate, so in addition to using anti-magnet or a superconductor bearing, static field or static magnetic fields The bearing is unstable. Electromagnetic bearings to work stably servo device or adjusting circuit parameters must be controlled. The actual use of the electromagnetic bearings are generally radial bearings, thrust bearings, servo control loop, dampers, speed sensor or position sensor components.angular contact bearings
