Okay!  I remember seeing that.  I also think I remember seeing a modification by you that took away the slots to have a full toroid?  Is that correct?  How did that test go?  I'm just so broke here I get anxious to ask questions.  :)  Are you planning on adding additional coils or extending the shaft to see what happens with more goodies?  It's so exciting!

I did do this simulation as well to check for clogging relative to the rotor in an 8-coil dual rotor setup, although it does look a little weird it's correct I think.

I think it's cool how the rotor sees basically no difference in torque.  I can't wait to see someone's build possibly powering itself.

I think Butch proposed the no slot toroid. So no test on my part.

I have no additional test planned. The clogging is very small. But, I find the constant pull of the magnet against the toroid core more of a issue. It is like strong gravity, but without the advantage of stored momentum as would be with a flywheel, so it is a constant torque restraint.

Honk's point about MPP opposed to silicon steel is good, but more at a much higher frequency then I'm using (50HZ). Also, I like the much higher permability of silicon steel in this situation to pass the flux from the toroid to the H type transformer.

@All, FYI, Honk is the top electronic circuit designer/builder that I've seen on this site.

@Blainiac, your simulation is interesting, but does not seem to have coils on the outside cores that would effect the torque.

Hey Blainiac,

I have gone back and opened, and re-saved one of your previous links...for whatever reason I can view, but not save this one.

Is it possible you may have accidentally coded this one or something ?

Regards...

Hmm, interesting.  The gif is stored here, I think that's what you're looking for Cap-Z-ro:

Ahh, yes.  I understand what you're saying and I tried to simulate that.  I didn't know exactly how I would introduce the counter-field produced by the coils in FEMM, but I'd love to figure out how to make a more accurate simulation.  Also you said the constant pull of the magnet against the toroid is more of an issue.  I think I read something you said earlier about if the magnet's closer it's less of a problem, correct?

No, the closer the magnet's to the toroid, the more torque required to turn the rotor. The LaFonte Group version would experience less torque, because of the shorter distance from rotor center. 

It may have been this comment, that when the H cut transformer is against the toroid, the clogging at the slits is very small. When the H cut transformer is pulled away and the magnets only sees the toroid, then the slit clogging is higher.

Posting new design in next few days, Butch

We have a new design we will post in a few days. It uses no permanent magnets, no exotic materials, just copper wire and powdered hard magnetic steel or ferrite.

Sounds very interesting and creative as usual butch...can't wait to see what you've come up with.

@Butch:  Any luck with that PM-less design?

@everyone else:  Anybody else still working on/designing this?

What Happened?   Or do I assume the "worst" and wait no more as it's
been "Buried"?

Anybody?

La Fonte group, Butch included, are on deserved vacations.

No wonder, anybody who contributed so many FE OU designs (at least 50-100 working concepts in just a few years), should be granted a "World sponsored pension" of some kind...

and where can one see a demonstration of these concepts in reality? i don't want to see all 50-100, just one would suffice... ::)
