The newest 500-kilowatt electric motor was tested in Russia


Demonstration tests of a promising electric motor on high-temperature superconductors were carried out as part of the acceptance of the results of the second stage of the joint project of the FPI and ZAO Superoks. Tests were conducted on a 500 kW unit. In the future, such power plants can be used for vertical taxi with take-off and landing, as well as all-electric ships.


Work on the creation of the latest electric motor started in 2016. As part of the current tests, the main modes of operation of the unit were demonstrated.

According to representatives of the Advanced Research Foundation, the use of superconducting materials in the future will allow the creation of hybrid and fully electric engines for the latest short- and medium-haul aircraft. Such aircraft will fully meet the advanced requirements of transport efficiency, reliability and fuel economy.

At the moment, to demonstrate the potential of a promising Technology 50 and 500 kW power plants have been developed. At the same time, earlier in the FPI they stated that in 2020 the flight of the first flying laboratory equipped with a high-temperature electric motor based on superconductors could take place.

    Currently, the most powerful three-phase electric motor is up to 315 kW. The largest electric motors weigh more than 1,5 tons and a length of more than 1,5 meters. The best electric motor for SIEMENS aircraft weighs over 50 kg. And its power is 260 kW. The motor is capable of providing takeoff of an aircraft weighing up to 2 tons. That's the way to work! Do not try to catch up with someone, you need to create your own and let us catch up with us !!!

    The transition to electric motion brings with it a problem in the form of the operation of the electric motor on the screw. For an electric motor, this is a fan load at which the required power has a cubic dependence on the speed. Pumping power through the engine involves losses, including copper losses, i.e. heat losses also grow in the same relationship. There is a problem with heat dissipation, the dimensions grow, the magnetic properties of the magnets fall if they are on the rotor. The use of superconductivity will reduce copper losses, which should result in a reduction in size. But the requirement to ensure the required torque on the shaft (quadratic dependence on the rotational speed) will not be removed, so the energy consumption will still remain high. In general, the use of superconductors is not enough to drastically improve energy efficiency. A qualitative improvement along with compactness can be achieved by abandoning the traditional approach to building the "electric motor-propeller" system, but this is already a different technological level, a new generation of electric motors. To confirm or deny this, experimental research is needed, as they say, the devil is in the details. So it's easy to start ...
