The units as shown are to heavy. We would have to redesign the
clutch
and
perhaps arrange the magnets in a different polar configuration for
more
attraction but less slippage. Simply explained; the mag./clutch is
designed
to slip from 100% down to about 3% by varying the gap between the
magnets
and the copper conductor. The input power rpms are always larger than
the
output rpms. in its intended design applications. However this might
get us
into trouble or be a benefit in our application. Have to test it.
Torque
stays the same though.
The micro toroid CVT. is our other option for matching rpms as well
as
being a disconnect clutch, affording wider range of turbo speed ratios
rpms., and perhaps a few other goodies. I am now designing a few
variations
of this device on paper.
This work is approaching a bench test on certain parts. Paul is busy
spinning gears and planning Hollywood stunt work while I am playing
with
colored pencils and magnets:)

Doug,
Would make an excellent damper if it could be designed light enough - but
I
don't know what power requirements are needed for the rare earth magnets.
Just think an infinitely variable gearbox, just by varying he air gap.
I like the alignment problem elimination as well.

Rare earth magnets have no power requirements.
They are created by superheating the material while applying a powerful
field.
The molecules align N/S and when cooled retain this alignment. The
superheating is what makes magnet so brittle.
By the way, be very careful handling powerful rare earth magnets bigger than
1/2". They are finger smashers.

Yes Mike
The little devils are strong. I also made a mistake of carrying a few with
me in my front pocket to impress the kids in Nepal. When I was running low
on funds I stopped by a ATM and.... yep , you guessed it, all cards with a
magnetic strip on them were wiped clean. They should work wonders around
computers as well:)
BTW George, the mag/clutch is promoted as a possible transmission but
actually it just controls the rpms. Their ARE similar ideas out there that
do use mag/connect gear ratios for in wheel motor cars. Perhaps we will see
them on the market in 7 to ten years.
