Zetilos Bearing Technology (Beijing) co., LTD., in Germany on the basis of the magnetic suspension bearing of transformation, is committed to the development of magnetic suspension system and the perfect combination of the ORC turbine expansion generator.

Magnetic suspension bearing is the use of electromagnetic force, will be supporting a stable suspension in the space, make no mechanical contact between bearing and the bearing parts of a high-performance bearing mechanical and electrical integration. It has no mechanical contact, no lubrication, high speed, high precision, low power consumption, intelligent control, etc. Due to the above characteristics, magnetic levitation bearing has widely application value in many fields, the United States, Japan, France, Germany and other countries as early as 2 o century magnetic levitation bearing was applied to molecular vortex pump, centrifugal compressor, the turbine engines and other large equipment, is also used in high-speed ultra-precision machine tools with magnetic bearing spindle, has also been successfully applied in the military equipment.

As a kind of typical electromechanical integration products, magnetic levitation bearing research involving mechanics, rotor dynamics and electromagnetism, control theory, sensor theory and computer science and other multi-disciplinary knowledge, has the very broad application prospects. Magnetic suspension bearing as an independent functional unit has a very wide application field. The magnetic suspension bearing is mainly used in high speed, high precision, automation, or low speed overloading, or vacuum clean environment requirements of high value-added products. Such as: CNC machine tools, high-speed milling machines, high-precision grinding machine, robot, vacuum pump, motor, turbine, large hydro-generator, aviation engine, satellite navigation system, artificial heart pump, sewage treatment plant, etc.

The development direction of magnetic suspension bearing:

(1) the research of superconducting magnetic levitation bearing. This kind of bearing is small, but there is a lot of bearing capacity. The research progress in the very great degree depends on the progress of the superconducting material. High temperature superconducting ceramic material due to its inherent properties and reasons of the specific processing technology, and the practical application is very limited, still need to have great breakthrough.

(2) the sensorless magnetic suspension bearing research. Sensorless detection in recent years, the combination of Magnetic suspension Bearing and two major research field of the latest research results, the birth of a new research direction -- Sensorless Magnetic suspension Bearing (Sensorless Magnetic Bearing or Self2SensingMagnetic Bearing). It does not need to design special position sensor, but indirectly by measuring the electric circuits of the internal signals of rotor position information.

(3) new material research. New material research success will no doubt make the magnetic suspension bearing breakthrough centrifugal force, magnetic saturation, hysteresis characteristics. In recent years have rare earth permanent magnet materials but also because of the rapid development of the light structure, low energy consumption and great application future. These new materials can be expected to popularization will effectively reduce the volume of magnetic bearing, the energy consumption,

And greatly improve the bearing capacity.

(4) the research of high-speed controller. Magnetic suspension bearing is mainly used for high speed equipment, its high speed operation speed controller is very necessary, the traditional controllers can not satisfy the requirement of magnetic suspension bearing high speed computing, adopting digital signal processor DSP as controller is a development direction of magnetic levitating bearing, adopting DSP as controller has the following advantages: easy to achieve more complex, the computational cost is larger and control algorithm, the controller is easier to modify parameters; Multiplication and addition by the hardware implementation, operation speed is very fast; Control pulse frequency is greatly increased, the system performance is very good improvement; Easy to implement signal processing and filter circuit, reduce the peripheral circuit.

(5) other type research of magnetic suspension bearing. Magnetic suspension bearing type can be varied, far more than the current three types, needs further research.
