That tickles my curiosity.
Can you show some of your DSO measurements?

Sure, soon enough I'll show lots of measurements on video.

Hi mscoffman,

You mean decrease the rpm? Sure, that's easy by lowering the voltage. The stage now is the find ways to decrease the losses so get a self-runner.

Steorn is using plastic, which is probably what I should eventually use, or some type of ceramic. What would be the hardest, yet affordable, plastic or ceramic?

Yes, to scale back the internal energy, without changing circuit drive
characteristics. Plastic is machinable, Ceramics are stronger, plastic has
larger thermal expansion characteristics as Steorn found out in his first
attempts. I kind of like glass for a PM machine. One would slide the guts
of the device into internal slots, once one knows what he is doing. (and
can afford the thermal molds.) They are satisfying for MIBS to smash,
and yet you can always reach around and pull out another one. ;)

Any ideas where to get the lowest friction bearings? A hard drive?  VCR?  CD player?

These guys claim to have the best low friction bearings, but don't see any price sheet,

hd motor have stepper that give no smooth movement.

for me VCR.

If the load and weight is not critical try bearing stone
http://www.adamant-kogyo.com/products/precision-components/clock/

a complete system in the old energy meter:

http://www.kanabona.com/kanabona/?q=energy_ceb_energy_meter_1979

or single ball bearing

there, for instance :

Those are their large bearings. What about the tiny ones?

I wonder what kind of bearings are in these,

One thing that helps is most of the weight is on the outer perimeter, and large radius.

Look at these two ceramic hobby bearing links:

Try the RC hobby section: jet turbines; They have some
8x9x27mm, this is small, I believe. These probably are not
optimal for you application but shows what can be done
spec. wise. I've heard that the very best bearings for
skateboarding are of the ceramic type.

http://www.bocabearings.com/main1.aspx?p=docs&id=16&source=adwords

http://www.vxb.com/page/bearings/PROD/8mm/2ISB-1

Enter: "roller skate bearings ceramic" into google. Get some
Teflon based lube too. You are going to have to have your
rotor balanced before any ball bearings can work well. Sleeve
bearings may be a better choice if you have continued high
vibrational loading.

Looks like *full* ceramic bearings cost a lot more, but I don't see any place that says they're better. Dry lubricant seems to have the lowest COF (coefficient of resistance). Sounds like the way to go. Too bad there's no inexpensive passive magnetic levitation bearings.

The bearing situation is for the radial variations. Any is supposedly CEMF.
This is the reason they go with the passive magnetic bearings.
