I don't say its so easy of course. At least to me, it was impossible ;-)
The right timming to tap the back spike is the main thing in the Adams mo=
tor.
If you see how the coils are switched you will see what in the Adams moto=
r they
are
switched FIRST in attractive mode, and then turned off in the right time =
to try
do useful work in repulsive mode at the last.
Of course the back spike exist in every coil, but in the Bedini motor it =
effect
isn't used.
If with this effect it's possible get OU regimes, I don't know, it's anot=
her
game.

Agreed, that explain the speed up in this type of motor.

No. The coils of the little girl motor are not bifilar. I was talking abo=
ut the
others motors of Bedini. As you know he do use bifilar coils in several d=
esigns.

It's a mistake. The reed switch was not my idea, good one though.
It has the frequency limitation but are very simple and cheap.
I could add the arc generated in a conmutator type of switch could collab=
orate
in
recharging the battery as in the Newman motor. You should know the anomal=
ous
effects observed in arcs by several researchers.
Good luck to you too, Juan.
