Russia is preparing an ultrafast super-engine

16

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.

    Looking at this engine, we can talk about the complete absence of theoretical justifications that would allow us to form a sufficient energy density and extremely positive effects based on magnetic force interactions. In addition, there is no mathematical justification for the change in the number of poles depending on the change in the radius of the rotor and stator.

        I want to say that at such rotational speeds it is very useful to use the potential of the environment in which the entire engine is located - this time. Then you can not be afraid that increasing the radius of the rotating parts will lead to destruction by centrifugal forces. By the way, this is the fundamental problem of all engineers to level centrifugal forces as a destructive process.

      There are no theoretical justifications yet. Our science is chewing on the old definitions of "what is electric current." But after studying the rules of Kirchhoff with their empirical amendments, you understand that the theory was hardly adjusted to what it actually is ... And el. the engine, as it was invented (or someone presented the idea from above) by Dolivo-Dobrovolsky in 1888, nothing has changed ...

      And what engine were you looking at? The one in the picture? It has nothing to do with the text of the article. In the picture is the Duyunov engine.

    This is a continuation of Putin's Message of March 1, 18. The same as there: it is necessary, perhaps, if it is, we will begin to design. Noodles for fools.

    Interestingly, the prototype has already tested bearings on a magnetic or gas cushion? And with what did Baalbek megaliths drill in antiquity?

      In Egypt, stones were manually drilled with copper pipes using abrasives.

        Well, yes, how did you drill holes with a 90-degree rotation? Curved copper tubes?

          And where in ancient Egypt did you see such holes? wink

      Speaking of magnetic or gas bearings. WHEN ROTATING AT HIGH SPEEDS, the magnetic spin or rotating magnetic flux, as in the Casimir effect, causes a linear magnetic flux vector. Just like a gas flow, it is similar to how you spin water in a glass of water with a spoon and it receives multidirectional flows along the periphery and in the center. Therefore, without the theory we are talking about, it also remains an unreliable method.

    Are there any ideas on the applied value of this development? If this was called an electric motor (and not just a ferromagnet in an alternating magnetic field), then there must be something that can take away torque at 1,5 million rpm. What could it be? I remembered an old joke about "glitches" ... Developers, no, it wasn't glitches?

      Absolutely right. This is what I often talk about, that we also need technologies for supplying and extracting both power and energy in its various forms. Therefore, it is extremely important to understand these issues. For example, we are talking about the fact that the kinetic energy of the pressure flow of water or air can be transformed into the work of both the mover and the variable magnetic flux. Those. Initially, everything is in one design, and not scattered across various devices.

    I don’t know what a breakthrough these electric motors will bring .... but in practice, what I do is service the water electric motors completely ... They break and burn for a sweet soul. PS There are electric motors made in the USSR with a quality mark, they work, but their century is coming to an end.
