Russia is preparing an ultrafast super-engine
Currently, the world is experiencing a boom in the use of electric motors. Automobile companies for the production of environmentally friendly electric cars are being created. Unmanned taxis, which are convertibles with electric engines, rise into the sky. Even electric powered aircraft are being developed.
In addition to innovative equipment, electric motors are also used in the machines themselves, with the help of which equipment, microelectronics, composite materials, medical devices, miniature drones, etc., are produced. To increase the productivity of microelectronics, miniaturization of machines for its production is required. Technological processes for creating microelectronics require drilling holes of a very small diameter, which requires maximum speeds of rotation of the shaft of a miniature machine.
Currently, the speed limit of the electric motor shaft is fixed at 1 rpm. However, Russian scientists from the Ufa State Aviation Technical University have taken the first real step towards overcoming this speed barrier, setting an ambitious goal of breaking the bar of 000 rpm and beyond. With the assistance of the Russian Science Foundation, physicists from Ufa have developed a theory and a software package that can be used to design such ultrafast electric motors.
Using their algorithm, scientists from Bashkiria found that special magnets made from an alloy of samarium and cobalt would be needed to assemble such a superengine. Magnetic products made from this alloy must be able to operate even at extremely high temperatures. Calculations show that special bearings on a magnetic or gas cushion are needed to create a prototype. Also, you can not do without a special cooling system that will remove excess heat with the help of metal and water. A virtual model constructed by Russian physicists showed that the engine could operate efficiently at a speed of 1 rpm.
The theoretical model developed by the Russians was also tested in practice on an experimental electric motor already existing in Ufa, which so far produces half a million revolutions per minute. The tests carried out showed the consistency of the model developed by physicists. The next ambitious goal of our physicists is to increase the rotational speed of the electric motor shaft to 1 revolutions per minute. These developments can bring Russian science to the cutting edge.
