Thanks for resources!

BTW, just tested the circuit and it's working better than expected. When the magnet is at top dead center, the circuit pulses the toroid coil for ~ 10us, then the circuit immediately shorts the toroid to maintain such current as long as possible as the magnet escapes the toroid. This method allows the energy stored in inductance to be used as useful energy to appreciably maintain the current pulse. Note, this method is for designs that rotate well above 10000 rpm.

This means it should be no problem to self-run. Lets hope Sean is wrong about the current pulse having to be constant.

I doubt any company will patent this circuit, but just to be safe and so it will remain open-source could as many people as possible down load the circuit file -->

Btw, the ones in the $8 fan are by now means magnetic levitation bearings. It's just a marketing stunt.


Well designed, well manufactured, unloaded electric motors seems to
"levitate" their rotors into the center their bearings as a matter of
course. This sounds like a marketing freebee to me too. They may
have to balance their fans a little better than normal to do this.

---

There are a couple of companies with videos on youtube that seem
to specialize in magnetic levitation for control purposes. They seem
to be able to do all sorts of amazing motion control, as long as one
is willing to include a strong magnet into the object being controlled.

I have continued interest in your "tiny orbo" repliocation.

Nice start of a replication Mags. Eventually you'll get the losses down. That might require different toroids or a lot more turns. In my "tiny orbo replication 2" there are ~ 170 turns on the toroid.

Thanks for the link. Those are active magnetic levitation  bearings. Do you know where to buy passive magnetic levitation bearings?
SKF may well make them as well. If so, why not ask them to send you a few for appraisal?

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

@Paul

On the vibration Tiny Orbo is experiencing. I notice that the
case-frame of the Steorn Orbo seems really stiff, It kind of
reminds me of a truck wheel hub in lucite plastic.

It would seem that high RPM's are somewhat the enemy of the "tiny"
moniker. Can't you slow the rep. rate down with an intentional delay
or pulse dropping (count division)? That way you can leave the
high RPM's for the future when you can machine-turn the motor's
rotor ect.? I'd be concerned that the high rep rate might cover up
an effect, as maximum RPM's is really a form of saturation - a trade
off of forces. Pulse dropping would not slow circuit reaction time
which should probably be as fast as you have tuned it for.

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?
