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.


Beyond Innovation equipmentElectric motors are also used in the machines themselves, with the help of which equipment, microelectronics, composite materials, medical devices, miniature drones, etc., etc. are produced. To increase the performance 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 shaft speeds of a miniature machine.

Currently, the speed limit of the shaft of an electric motor is fixed at 1 rpm. However, Russian scientists from the Ufa State Aviation Technical University took the first real step towards overcoming this speed barrier, setting an ambitious goal - to cross the bar at 000 rpm and above. With the assistance of the Russian Science Foundation, physicists from Ufa developed a theory and a software package with which to design such ultra-fast electric motors.

Using their algorithm, scientists from Bashkiria found that to assemble such a super-engine, special magnets from an alloy of samarium and cobalt will be needed. Magnetic products from this alloy must be able to work even at extremely high temperatures. Calculations show that to create a prototype, special bearings on a magnetic or gas cushion are needed. Also, you can not do without a special cooling system, which will remove excess heat with the help of metal and water. A virtual model designed by Russian physicists showed that the engine can 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 performed showed the viability of the model developed by physicists. The next ambitious goal of our physicists is to bring the rotational speed of the shaft of an electric motor to 1 rpm. These developments can bring Russian science to the forefront.

    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 speeds of rotation it is very useful to use the potential of the environment in which the entire engine is located - this is the 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.

      And there are no theoretical justifications yet. Our science is chewing on the old definitions of "what is electric current". But after studying Kirchhoff's rules with their empirical amendments, you understand that the theory was hardly fitted to what it really is ... the engine was invented (or the idea was presented by someone from above) by Dolivo-Dobrovolsky in 1888, so 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. WHILE ROTATING AT HIGH SPEEDS, the magnetic spin or rotating magnetic flux, as in the Casimir effect, produces a linear magnetic flux vector. Just like a gas stream, it’s similar to how you unwind water with a spoon in a glass of water and it receives multidirectional flows along the periphery and in the center. Therefore, without the theory we are talking about, this 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 say, that technologies of supply and selection and power and energy in its various forms are also needed. Therefore, it is imperative to understand these issues. For example, we are talking about the fact that the kinetic energy of a pressure stream of water or air can be transformed into the work of both a mover and an alternating magnetic flux. Those. initially all 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.
