"Tiny Orbo Replication" over 100% efficiency

[PaulLowrance]

forgot to mention that the current pulse was decreased to 12 degrees while advancing it a bit, which made hardly no difference in rpm. So that cut the electrical resistance losses by nearly half.

Passive magnetic levitation bearing idea,

Ok...obviously removing lubrication will speed the bearing
up initially, but the cost is faster bearing race wear which
may not be a problem initially. Also, I expect the unit will
be subjected to very little mechanical shock initially which
is a bearing race wear problem also mitigated by the lubricant.

I think the powerful vibration the occurs in a device has to
do with "finite element analysis of rotating members"
with the fact that vibration causes a shift in the center
of gravity of a complex shaped rotating mass as viewed
from outside. (even if the mass is perfectly stiff) the vibration
occurs because a source excites a vibration that only occurs
when it exciting force exceeds the z-axis rotational momentum of the
rotor mass. So the rotational momentum act as resisting force,
but not as a damping force. What this means is that the
bearing lubricant is the primary damping force trying to
kill off the random force excitations before they build up and
start the rotor vibrating, enhanced only at certain RPM's.
So I think you are going to have luck with your device
but as it goes through various resonant RPM's it will show
a tendency for large scale vibrations. This occurs because
the rotor shape is not necessarily how one would want it to be
theoretically. That is, a stiff shaft with rotational symmetry and
top to bottom symmetry through the middle, with a bearing at
each end of the shaft.

This damping force is primary only lenz magnetic forces in passive
magnetic bearings
