Hmm.... that's interesting, but I wonder if there is a translation problem. The vacuum running... it is a real problem to sustain high voltages in any but the very hardest vacuums. Even the "vacuum" of Earth's orbit is conductive enough to make it really difficult to get voltages over 1 kV.

For example in my "terrela" anatmosphere vacuum chamber, using the 2-stage vane pump which pulls down to 25-30 microns or so, the maximum voltage can only rise to 900 volts or so before the highly conductive plasma forms.

With very close electrode spacing the standoff voltage will be even less. Of course if they are using turbopumps for roughing and an ion or oil-diffusion pump for final vacuum they can get below the "glow discharge" region and begin to build up higher voltages, but then, shouldn't you have to include the vacuum system power as part of the motor's input power?

I haven't yet tried my Mendocino maglev esmotor in the chamber; maybe I'll dust it all off, get it down from the shelf and try it out. Things like VDG generators, corona motors, and so on usually don't work in ordinary lab vacuums. I have tested a simple corona motor in my chamber and it doesn't work, although it does make nice "st.elmo's fire" anode tufts.

ゴシック]The clear case around ESM65-TR1 keeps the vacuum environment around ESM65-TR1. Keeping the vacuum environment around ESM65-TR1 reduces the possibility of "spark generating".
The sound is the wind noise of the propeller attached to the tip of equipment and the sound of a vacuum pump.

Look at the "Spark generating" in this video:

Do you not believe me that a very hard vacuum is needed for high voltages in vacuum? Do you not believe my instrumental measurements?

http://en.wikipedia.org/wiki/Paschen%27s_law

I see the sparks in that last video; they prove that that particular device isn't under vacuum, and it is a Franklin motor like the first one I linked up above which also sparks to transfer charge from the inputs to the balls.

If the ESM65-TR1 is running in vacuum, it is in a vacuum that is below the "Paschen limit", the extreme left end of this set of curves. Otherwise you would see a glow discharge as I demonstrated, and the voltage could not rise to "electrostatic" levels, as I also showed. If that is the case, then the vacuum is produced by a high-vacuum system involving turbo or oil-diffusion pumps, roughed or backed by a vane pump, and perhaps even augmented by a diode-type ion pump once the pressure gets into the real "hard" vacuum range. I am not saying that this is impossible, what I am saying is that if such a vacuum system is in use, it must be considered part of the motor, and the power to run the pumps to establish and maintain the vacuum must be considered as part of the power input to the motor.
