series bearing be used to adjust the circuit parameters control

Using electric force, magnetic force of the shaft suspension sliding bearings. Electric field force is electrostatic series bearing suspension with magnetic force suspension of magnetic bearings (see figure), electric field strength and the magnetic field strength is combined together suspension bearings. A bearing both electrodes have the poles in the circuit connecting the capacitor and inductor corresponding to each other tuner, NNCF series bearing the stiffness is much higher than the first two, and the corresponding displacement of the maximum force is very small. Electromagnetic bearings for shaft and bearing no direct contact, no lubrication, can be in a vacuum and over a wide temperature range, friction is small, not the speed limit, long life, the structure can be diversified. Static bearing requires a lot of field strength, the application is limited, use only a few meter. Magnetic bearings with a larger carrying capacity and stiffness, have been used in ultra high-speed trains, ultra high-speed centrifuges, hydro, spacecraft angular momentum flywheels, flow meters, Tapered bearing density meter, power meter, vacuum pumps, precision current regulator and gyroscopes. With the development of magnetic and electronic technology, electromagnetic bearing applications are growing. Electric force and electric field strength, electric displacement and the electrode area is proportional to the magnetic field strength and the magnetic field strength is proportional to the magnetic flux density and magnetic area. Select the appropriate electric or magnetic field parameters and geometry, slim bearings get some bearing load capacity and stiffness. Electrostatic attraction between the magnetic attraction is inversely proportional to the square or the distance of the object, according to Hugh Aner theorem, series bearing this system is statically indeterminate statics, so in addition to the use of anti-bearing outer magnets or superconductors, in the electrostatic field or static magnetic field work bearing is unstable. For the magnetic bearing is stable, servo device or method must be used to adjust the circuit parameters control. The actual use of the general magnetic bearing by radial bearings, thrust bearings, servo-control loop, dampers, speed sensor or position sensor and other components.
