The application status of rare earth permanent magnet motor on the air in the developed countries, the application of rare earth permanent magnet motor in aviation has become more widely, the domestic relative lag, so far only a few new model aircraft available. The main application of rare earth permanent magnet motor in plane object for all kinds of electric power system. Electric power system based on motor drive components for the implementation of the system, widely used in the aircraft's flight control system, environment control system, brake system, fuel and starting system, etc. Used on aircraft actuation system there are four hydraulic, electric power, pneumatic and mechanical. The most widely used hydraulic actuator system; But is currently developing and the most promising system is electric power system. With rare earth permanent magnetic material and high power semiconductor devices and the development of the microprocessor, the electric power system has developed to compete with the hydraulic actuator system. Process knowledge: magnetite crystals like rechargeable batteries. Today, from the university of tubingen in Germany James Byrne and colleagues found that a common magnetic minerals - - Minor magnetite grains can also act as electron acceptor and the role of electron donors, so like the battery work efficiently. He let by bacillus genera and red pseudomonas bacteria community grows in the magnets, and then found that bacillus genus, the electronic 'on' to crystal can be red pseudomonas genus from crystal for electronics. In the natural environment, the two reactions may, in accordance with the cycle of day and night or fluctuation tide period, each type of bacteria is active in the cycle of different point in time. He said, for the bacteria, magnetite crystals like natural rechargeable batteries work: by charging to coli, red pseudomonas belong to electricity. From the university of Aarhus, Denmark's Lars Peter Nielsen, says the finding is exciting, and it provides about magnets in the geomicrobiology as a kind of mineral with complete information on multiple roles. According to the different needs of bacteria, the magnet can be used as a conductor, also can be electronic storage tank and source.
