    Warren:
   Looks like it's spinning down quite fast. Not sure why with mag bearings. Needs to add another pair of disc mags
to the top on both sides to hold the shaft steady. Then add an end cap mag to hold the rotor on the horizontal plane.
I did one of these some time ago and tried to make a motor with it but the shaft bearings had such magnetic interference
that the coils were bathed in it before I switched it on. Not to mention the out of balance but oh boy, did the bearings
work great.
   Think maybe if the center had a metal plate say 1/4" thick to shield the center bearings from the outer ones, might
be a different story.

       DougIs
 it turning on its own, or is that just a push to demonstrate
 the bearings levitating it?Cheers
 Warren
