The 'problem' with neos is that they do almost not degauss. But you need degaussing to harness the potential energy in magnets. So how can a magnetmotor work without this?

You have come up with several "good" magnetmotors designs yourself without any stickyspots.
At least on papper that is.....have you taken your time and actually built any of your devices?
Before doing this you can't deny the fact that we might find a way to build a working OU motor.
And the journey itself is a lot of fun....otherwise you wouldn't hang around here!!

I'm sure you have already come across PESN and may have read the story where it's owner, Sterling D. Allan, claimed to have contacted some guy in South America that patented a design very similar to Brady's, but long before he came on the scene.  He also suspected that this was where Brady got the idea from.  Anyway, point is, apart from the usual harassment, the other problem the patent holder had was degaussing magnets, which convinced him that it wasn't worth pursuing.  These would have been 'old' magnet-types of course.  I'm convinced that modern neo's are immune.  A notion borne out somewhat by Steorn's gauss measurements before and after their week-long (maybe longer?) test which showed no weakening had taken place.

And suffice it to say that Neos are soon to be relegated to relative ceramic magnet status.....as new materials breakthroughs are providing dizzying results as we speak.

I've recently read of new alloy combination breakthroughs that could yield as high as 100mgo, theoretical on paper.
NdFeb magnets can yield 64mgo maximum. But today's commercial available NdFebs only yield 54mgo maximum.
The new ones will resist demagnezitaton even better than neos and be cheaper as they only contained 25% neodymium.

I forgot where I read about this. Can you please post a link if you have any to share?

The Domains in Neo magnets are very good...They pull each other
back up given thermal agitation...I feel they *could* be erased by
agitation that heats the micro-domains up to the Currie temperature.
This is *minus* a few defective domains. The problem is, those few
defective domains can change the sorted strength of the magnets
relative to one another. So erasure could easily change the *gradient*
in an array. This would likely follow a bathtub like (infant mortality)
curve and it normally doesn't terminate in zero field strength. So
Folks, it pays to know your gradients.

Other (old magnet) materials though *can be erased*...and this erasure
can result in apparent overunity energy when it is taking place. So
therefore "overunity in machine" claims are often followed by "magnetic
erasure" claims. Implication =>  use Neo, or better, magnets in your
potential overunity devices or risk wasting everyone's time.

Hi,
In looking at the design I have often wondered why the sticky spot cant be over come with electromagnets? The charging would be done at an angular offset prior to the pass point. Then when that point is passed the coils merely are charged in attraction or repulsion or chargeless. This can be done passively on the rotor. The charge coil can be placed in the rotor and the wires run to the coil at an after point.
