The development of European and American countries auto bearing

In view of the present situation of the European and American countries, automobile industry, the flywheel systems ( AFS) Is produced in 1115 grams of fruit farm and wild car as the prototype of the flywheel battery cars AFS20: in the four aspects of fire, west Germany ( Doors company has developed a long 1. M wide 0. 75 M of the flywheel battery, can provide 3 mw of power, and can store 30% of the car can: the United States grams of M state university. 一个。 Pichot, state university of north Carolina G. D。 Buckner, etc, with the support of people in the United States department of defense line of the maglev flywheel energy storage applied research on combat vehicles, the maglev flywheel energy storage in the 2000 min, can provide 5 mw peak power for the weapon system, 350 kw of continuous power for dynamic systems: Germany's electricity company made an electromagnetic power accumulator ( MDS) , MDS is rotating flywheel energy storage device, installed inside a double electronic motor, root according to need, motor or as a motor or as a generator, the energy storage valued 2100 kg, 78 mj energy storage, power 500 w, the kinetic energy of the magnetic memory MDS can work in the vehicle when the electrical energy will be stored for fast acceleration or can provide external devices. Figure 3 - 6 and figure 37 shows NASA with magnetic levitation bearing application in flywheel energy storage in flywheel energy storage technology started late in China. At the beginning of the 21st century of tsinghua university, wuhan university of science and technology, two Ann traffic big science, Chinese Academy of Sciences institute of electrical and other units began to research of flywheel energy storage. Tsinghua university studied the maglev flywheel for satellite attitude control, wuhan university of science and technology of vehicle flywheel battery flywheel structure design are studied, xi 'an jiaotong university studied the spaceborne nonlinear electromechanical coupling vibration control problem of magnetic suspension flywheel system. 米
