If we could find 4 radially magnetized ring magnets (poles are at inner & outer part of ring), and a few normal magnets (axially magnetized), then it shouldn't be too difficult to make magnetic levitation.

Here's some radially magnetized magnets, a bit large and too expensive for me, $50 each

!!!!i've seen the light!

those videos of the mag bearings were great! try it you never know!  you might even want to, watch out for the rodin coil!

lol

I wonder which ceramic ball bearing has the lowest friction,

ABEC-5
http://www.vxb.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=kit7955&Store_Code=bearings

or

ABEC #1
http://www.bocabearings.com/main1.aspx?p=product&id=6827&n=#YCWK83-YZZ_AF2


One is ABEC-5, and the other is ABEC #1, whatever that means.


btw, yesterday I discovered that one of my ball bearings will fit inside a larger one. By rotating it by hand the outer one does not spin because there's not enough force on it, but I'd bet it would spin at high rpm's, which should help reduce the friction that much more.

ABEC number (odd integers only, higher is better) strictly represent (an average)
tolerance of all three dimensions of bearing. Not other stuff, which is more probably
important to bearing operation.

Ceramic balls are harder and 30% lighter then steel, so they can withstand higher RPM
due to centripetal forces not damaging the outer race.

Lubrication is important so in sealed bearing one is probably going to need
to specify the application.

Found these in the following official article link;

http://www.sme.org/cgi-bin/find-articles.pl?&00no0052&ME&20001107&&SME&#article

As to the compound bearings in the videos, I notice that too.

Then that would make this the better choice of the two,
ABEC-5
http://www.vxb.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=kit7955&Store_Code=bearings

It says it's good to 100,000 rpm. Yeah, I could just imagine the "tiny orbo replication" spinning at 100,000 rpm, lol. Suuuurrrrre!  ;D    That would be something else. It's possible because it's only 1.1" OD.


I agree, lubrication seems very important. Since my application is for light forces on the bearing (hopefully), then a light weight lubrication is better. Is it difficult to remove the lubrication cap, remove the factory lubrication, and apply different lubrication?

I'm telling you right now, if I had a magnetic levitation bearing that was good to 20,000 rpm, it would be easy to make a self-runner!

It's amazing what difference between ball bearing and ball bearing. I just extracted another ball bearing from a CPU fan. This was from a massive fancy fan for a high end CPU. Well, at least in it's day. The ball bearing looks in good shape, but it seems that the lubrication is too thick because the "tiny orbo replication 2" can't even run. Although it's by far the quietest of all the ball bearings. I can hardly hear it. The best ball bearing so far is the noisiest, sounding like sand paper.

This pdf says adding grease or oil to ball bearings will make it go slower,

A popular misconception is that by adding grease or oil to a ball bearing it will go faster
when in reality the opposite is true. It will slow it down. Why? To put it simply,
“kinematic viscosity.�

Well, the old dead 1st ball bearing was just revived by opening it up and removing all of the grease. Wow, it's as quiet as a church mouse, and is doing better than the best one so far.  ;D

I think grease is best for heavier loads. In the case of the "tiny orbo replication," it's as light as a feather. So maybe no lubrication is best for lowest friction.

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.

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
