In the summer of 2012, the Russian Superconductor Corporation completed the preparation of experimental documentation and the manufacture of an experimental sample of a high-power and energy-intensive kinetic energy storage (NKE). Upon completion of the fabrication and acceptance tests, full-fledged bench tests of the drive were performed with testing the performance of all its nodes, as well as some basic operating modes. This article describes the achieved results of the tests performed for the cyclic operation of a high-power and energy-intensive kinetic energy storage device created.

Taking into account the conversion losses from electrical to mechanical, and back from mechanical to electrical, the efficiency indicator should be within 0.67 (67%)
If everything is measured in kW, for clarity, we take the value of 1 kW of electrical energy. We accelerate the flywheel and accumulate 0.8 kW of mechanical energy. Next, generate electricity by absorbing mechanical energy, we get 0.67 kW of electrical energy. according to the rules of classical physics. In experience, a different indicator of 0.97 for the production of 0.97 kW of electrical energy, we need to spend 1.16 kW of mechanical. 1.16 -0.8 = 0.36 kW of mechanical energy is unknown from where it appeared, is not it.
