EXPLANATIONS OF THE VIDEOS.
The Input Bat. is 'chopped/minced' with a Reed Relay.
The motor is not wired to any load.
It sounds like you could run this motor (with a fan) for a long time without depleting the bat but
even slightly replenish it depending of the mood of the said bat and the tuning of a pot. :))
Due to shabby desing (glue problem, for ex.) , I did not try to run
this motor 'alone' for a long time.
I guess that a good fitter could have such a (better) motor running
for years!!!
---------------------
The vids were taken a couple of months after this (clicable for enlargement)
picture was designed.
In the vids the capacitor is not
wired, and the motor is absolutely left alone!

Over Unity (Cop > 1) is great, indeed, but wat about mere 'Unity'?
