I work in a machine shop with some pretty smart guys.  we are not engineers though nor are we physics majors.  we do believe that the Perendev design would work if all of the bugs were worked out.  we built this motor a few months ago right before i stumbled across overunity.com.  we used 0.5in x 1in neodymium magnets and it does not run.  we set it up in repulsion and have tried a few different combinations of magnets in the stator.  through researching this device i was blown away by all of the different devices and ideas that people have come up with.  if anyone has any input good or bad i am all ears.
Nice work, but I hope you know that angled magnets are not more productive than straight ones. You cannot change magnetic directivity that easy. A magnetic flux isn't a moving mass that squirts magnetic energy in one direction. Magnets are a closed loops of magnetism where pretty much nothing happens as long the magnetism in the magnet isn't changing - like in a permanent magnet. Permanent magnets contains only potential energy. No work will be carried out if this potential doesn't change. If it do, the magnetism in the magnet would rapidly degauss and be useless in seconds if the motor should work based on magnetism. But keep trying for learning at least :)

i have read about the magnets degausing and i am not convinced that this happens.  if you can point me to some convincing evidence i will be happy to read up on it.  we angled the magnets because the patent called for angled magnets.

These statements are based on appearance and conjecture only.  I challenge you, Vidar, to deguass a neodymium magnet with any method other than heat, structural or chemical decomposition, or a robust capacitor array!  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.

You do know that Perendev motor never worked don't you. He was a con man. He has finally been arrested. See: http://pesn.com/2010/04/24/9501640_Michael_J_Brady_arrested_for_embezzlement/

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.

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.

For what it's worth, here is what I would like to try.

I would position .5 x 2 inch neodymium magnets at about 30 degrees from perpendicular evenly around a rotator. Each magnet would have a Netic half-sleeve magnetic shield (from magnetic-shield.com) covering the leading half of these magnets and extending about a quarter inch beyond the magnet.

The stator would have similar magnets positioned at 30 degrees from perpendicular evenly spaced (the rotator and stator magnets would be parallel). Half sleves of Netic shields would be placed on the stator magnets to shield approaching rotator magnet fields, again extending about a quarter inch beyond the magnet.

As a magnet from the rotator approached a stator magnet, the magnetic shields of both magnets would greatly reduce the repulsive force tending to stop the rotation. As a rotator magnet reached the stator magnet the full repulsive magnetic forces would propel the rotator on.

That's what I would try. You seem much more energetic so I would like to know if you get any results.

my magnets are neodymium...  giant-killer:  not sure i have a complete mental picture of what you are explaining, feel free to elaborate more if you like...  i was talking with a friend who showed me a video today on the "coral castle."  something i'd never seen before and the builder used a wheel with magnets on it...

gobob, i like that idea.  i am going to stew on that for a while...  Do i need to have the same number of magnets in the rotor and the stator?  or do i want one more set of magnets in the stator than are in the rotor?
