Reading the patent again this appears to refer to the inner rotor coils, not the outer rotor coils, which only develop a weak flux into the output stator, as their steel poles have large airgaps in the closing members either side.

Hello all,
Since we're back to discussing the inner stationary rotor, I want to finish my thoughts which I previously mentioned to Ufo. On my device I have some difficulty with attachments/images. Therefore I'll attempt to post the images here and then add my comments via edits.

Looks like I have the four images attached. Hopefully they are of proper size.
1st is a photo from subject's website of the completed 'rotor' to give some reference to the hardware and size.
2nd is a diagram lifted from a textbook or educational website. Sorry but I don't have a link. Google can find it for you. It shows the way a typical generator field 2-pole rotor is wound. The winding current is fed via slip rings or other method using a DC source. The winding is placed in slots which are in between teeth around the surface. Shown is a cross section perpendicular to the centerline of rotation (shaft). In the slots see circles representing the current. An X in the circle represents current direction into the screen. A dot in the circle represents current direction out the screen.
Note the magnetic field lines, and the direction of the cumulative field or as I call it, flux vector.
3rd attachment is from the patent showing how the rotor is connected.
4th is the center of the above diagram which I snipped out and enlarged. Then I drew in two circles in each slot to represent the two coil sides which lay in the slot. Each tooth on this core (16 total) is shown to have a 5 turn coil. So each of the circles drawn in the slots, represents 5 wires. Next I traced out the currents on the wiring diagram above from the 8 channels + & -, using conventional current direction, + to - outside the source. With this I am able to assign current direction to each coil side (circle) and add the X or dot, out of or into screen.
When the two coil sides in a slot have opposing equal currents, the net mmf contribution is zero. So it is apparent that 14 of the slots contain opposing coil sides therefore make no contribution to the field. Only slots between teeth 16 & 1 and between 8 & 9 have coils sides which aid each other and contribute. Hence the rotor will have effectively two coils of 5 turns each. This means only 12.5% of the copper is utilized at any instant. Actually less if you consider end-turns. About 90% of the copper is along for the ride or worse, needlessly wasting power and heating the machine.
It is for these reasons such cores are typically wound using lap or overlaid coils where the coil span (distance between coil sides) is nearly equal to the pole pitch. Winding such a core as they have done makes absolutely no sense.

Hello All,

This company is making claims that seems to breaks all laws of conservation of energy.

Are there any true verified documents from independent companies?

This is nothing more then a transformer, I think by looking at this simple design they could be using Back EMF.

This is a simple transformer. ?

Agree Bistandar. That's how the inner rotor is configured. It imitates a permanent magnet spinning around. The outer rotor is wired the same way and in sync with the inner rotor and reinforces the inner rotor. Per his patent images, the center stator is wired exactly as a 4 pole 3 phase generator stator. So basically no different from a regular 3 phase generator. For those of us that don't know, you can read this link https://electricalacademia.com/synchronous-machines/three-phase-ac-generator-working/ for a basic explanation of a 2 pole and 4 pole 3 phase generator.

Makes no sense unless it happens to work      If you are basing your statement on their patent info you do know patents often mislead with details that make it impossible for others to copy their work.   Maybe consider this is intentional misdirection...
