The future development of magnetic suspension bearing will mainly focus on the following aspects

Superconducting magnetic levitation bearing, the volume of this bearing is very small, but there are a lot of bearing capacity. But, to a large extent the progress depends on the development of high temperature superconducting material, it is difficult to have a big breakthrough in recent years since the detection of magnetic suspension bearing; Traditional magnetic suspension bearing need sensors to detect position signal, due to the deposit in the sensor, the bearing axial size bigger, dynamic performance of the system is reduced, the surface and high cost, low reliability. Since the detection of magnetic suspension bearing shaft position is detected through bearing its own signal directly, do not need to be independent of displacement sensor, can simplify the structure and is the manufacturing cost reduction, in industry has a wide application prospect of the electromagnetic and permanent magnet hybrid magnetic suspension bearing, the bearing is mainly produced by water long magnet magnetic field instead of the electromagnet bias current of the magnetic field generated, in order to reduce the stator magnetic levitating bearing, the volume and weight of the power amplifier, has a good application prospect in the aircraft engine. Base hand global optimization design: in addition to let itself and magnetic levitating bearing rotor system meet the mechanical requirements, from the perspective of system also consider the stability, reliability and economy of magnetic suspension bearing for magnetic suspension bearing products, to create a wider application prospect. Used in a variety of advanced controller and power amplifier: in order to achieve higher performance requirements, the control links in the magnetic suspension bearing system is playing an increasingly important role, the controller of the digital, integration and computerization of magnetic suspension bearing hard systems tend to be more structured, modular, it is good for its standardization, seriation and commercialization. And the development of corresponding software increasingly modern control theory is used to realize all kinds of control algorithm, such as the sliding mode control, fuzzy control, adaptive control of nonlinear system and control, mu control, etc. , making it more 'flexible', and to the multi-functional and intelligent direction. Power amplifier is to adopt high efficiency switching power amplifier, etc to replace continuous power amplifier. Second, the Suggestions for development strategy of high-end bearing ( A) Research and development system construction of China's high-end research and development of bearing system is caused by incomplete behind one of the main factors in the high-end bearing in China. According to according to the principles of engineering and practical to carry out the administration, production, study and research, with reasonable combination, is an important means of development of China's high-end bearing. In promoting the research and development of high-end bearing system construction process, the need to carefully analyze market, on the basis of market improve and perfect the economic law to guide research and development system, to achieve the purpose of stronger bearing industry in our country. 1. Guide enterprises play a role of the main body of technology innovation in science and technology has the practical value, with product design, investment, production organization, marketing, product service, combination of resource factors, form the industry, can benefit society finally. Place is the technology and resources enterprise, enterprise is one of the main places of applied technology research and basic research. A healthy, energetic technology research and development system, the enterprise, especially with the influence of the leading enterprises must become the main body of technological innovation.
