No
Thanks for your explanation, but the kinetic energy or angular momentum of the rotor (flywheel) does not enter into the power and efficiency calculations of the motor in the video demonstration because it is spinning at a constant speed at the point where the experimenter makes the measurements and calculations.
As you can plainly see in the Russian paper you posted, they are interested in and measure the acceleration (and deceleration) of the flywheel. A change in speed (RPM) is needed to use or store energy in the flywheel. That energy is simply irrelevant in a constant speed power or efficiency calculation. That is why I call the bad math guy in the subject video an idiot.
Sorry if you disagree but no sense of me posting more. I have explained my stated opinion.
Thanks for the discussion.
