they plug this into the wall to bring the motor up to speed
Then unplug the power.
The machine appears to be operating itself
Plus a substantial load.
So what's your impression sm0ky2? Think it is the real McCoy?
If so, do you think it has a limited life-span--maybe working the little neo magnets in such
a way they eventually lose their field strength?
The one thing about this I clearly think is important, is the starting cycle. Pretty sure
the big motor is a typical induction motor--notice it doesn't ramp-up rapidly as though
it was directly connected to the mains. Instead, it appears to be powered by way of
a variable frequency drive that brings the motor up-to-speed much slower. Also, when
at speed, the motor appears to be running at much less than 50 or 60 Hz. So in my
manner of thinking, the motor itself is just as important as the fabricated generator
with all the round neo magnets exposed. I would bet the electronics are playing some
sort of "trick" with the frequency and phasing. I also suspect the motor drive circuits
are not continuously powering the motor. There are probably moments between cycles
when the electronics are recovering from the motor, using it as an additional generator.
To me this is the only reason such a large induction motor would be used is if it is also
part of the generation mechanism.
