Rotating magnetic field

[DomiChi]

Hello everybody
In this document http://www.nuenergy.org/theoretical-self-sustaining-permanent-magnet-motor/ we can see a diagram where we can think that with this magnets configuration we obtain a rotating field.
I am not a magnetism specialist, is there somebody who can confirm that?
A FEMM simulation will be OK for me, but I don't know how to in FEMM.
Can we obtain the same with flat magnets (easier to find, this one http://www.supermagnete.de/Q-40-20-05-N for example).
Thanks in advance

It seems that this magnets configuration is also in the Johnson motor, in the Minato from http://www.fdp.nu/thebook/calloway.asp?URL=calloway.asp (the R.Colloway "how to build" but with non-sufficient description).
It will be interesting if somebody can simulate that in FEMM. In R.Calloway "how to build" he used flat magnets, but does not give angle, nor dimensions.

And in Europe it will be cost less to buy flat magnets in DE than curve magnets in US (even from France where I am).

Please, you how knows FEMM, help me in making for me this simulation. I an tired to by magnet for nothing good.

If it is because I do not put a drawing that you cannot do it. I explain you the drawing:
Imagine that you have these magnets that are 40 mm x 20mm x 5mm N42, magnetized in sickness. You make a bare by covering 20mm of the 40mm of a magnet with another magnet. You do that with 25 magnets. When the bare is finish you curve it around a circle of 25cm diameter. That is for a part of the rotor. South outside the round.
For the stator, http://www.supermagnete.de/S-20-10-N discs (also N42, and strong) join, around the inside perimeter (inside perimeter of stator is 1,5 cm more than outside rotors magnets). North go to the rotor shaft. For eventual better results we can put a metal sheet behind, around the discs circle.
Thanks in advance.

No voluntary to help me?

As it is a common configuration (Johnson, Minato, ...) I think it is not only for me.

If you with FEMM can give me the best implantation, I could buy the magnets and test it quickly  for every body.

Think of a magnetic field as dynamic leverage.   Myriad levers looking to engage.  One may leverage one field against another at far field, while inducing electricity at near field. Examine carefully the field density gradient of a given PM.  Given the exponentially increasing forays into nano-materials, one can see that solid state power generation is not far off.  If it hasn't already been exploited.


Magnetism and will power are nearly identical in various aspects.


One must have the will power to harness magnetism.
