GerryYour thinking is helpful.An RV without rotor filled with ferrite, being better than the RV with free spining rotor. I think that is what you are saying?

Hi Warren, Ole,According to those patents and some other Russian information from friend Alexey on Ferd site.
This is how it goes....For BLDC Outrunner motors we can take apart the windings and rewind each pole as a bifilar winding.One winding is then a primary the other is a secondary. Hooked in Star or Delta as required.
Each pole around the outside becomes a little power transformer of it's own. Only the magnetic field from each transformer is chased around the outside by a rotating magnet (the outer rotor).Amplifying the input field.
We can rewind 3 phase motors by same way doubling up the winds (with a primary and secondary) if there's space to do so.
The drawback with 3 phase motor's is it sucks much energy out of the input field.... just to mechanically rotate the rotor which has large slip angle & is driven by Eddy currents.
So again each 3 phase winding is then an input and output transformer with ADDITIONAL extra external magnetic field not used in a normal transformer.This EXTRA field rotates around the circular core at exactly same speed as input current's field and arrives back at each coil/transformer just in time to re-enforce the original field.This apparently amplifies the original field.
So main thing with 3 phase motor is to remove the energy sucking rotor & fill the space with low eddy current but good conductor of magnetic field. In the patents they say stacked laminates ....but thinking stuffing the space with Ferrite powders even Iron filings in epoxy might work.

GerryDon't have a need to appologise, this is not a private m, and wow! Your input is certainly welcome.I don' t have a clue what I am doing.I am a materials and processes guy.If I know what it looks like, and what it does, I can likely make it, as long as the information, I am getting, is correct.The insides of ac electric motors have been voodoo magic, whenever I have taken one apart. They are not intuitive.The forces at play are invisible, just looking at the parts and pieces when you take it appart. There is no mechanical contact for the eyes to perceive. That central armature core seems to contain nothing of mechanical interest, except being made of laminations tightly packed together.Who would imagine that it could turn by itself without contact?It is complete madness that someone actually brought these things together to run on electricity, and they actually work.Such a mind was indeed awsome.So now here we are trying to ponder the next step. This is going to take every mind we can muster, trying to figure it out, and then build them.That motor coil I took out is an impressive bit of craftsmanship that appears to be quite a challenge to duplicate, let alone build something even better, on the bones of that one.What I appear to lack is the coceptual framework of what we hope to acheive.How are the people who are making these things work doing it?Cheers Warren

Hi Warren, OleExcuse me barging in on your conversation here.
Just like to say if you are looking at implementing the Molina-Martinez patent mentioned above.While you are there... download this one also.... https://patents. google.com/patent/ US20040007932
It is virtually identical effect claimed by another person "Chung Hyung".This one is a good read because it goes into detail about how to wind the input & output windings in the slots.It also shows some other techniques to make the magnetic field move pole to pole ...if using single phase etc.
eg Shaded pole or phase shifting capacitor (like with Hectors RV ing technique).

Hi Warren,
Perhaps the stator can be used as it is according to the Molina-Martinez patent application that Gerry refers to at the ferd yahoo group: https://patents.google.com/ patent/US20030168921A1/en
This patent application also claims excess energy without having to step through the poles. The poles are the normal fixed ones made rotating by using three phased alternating current. This is the normal Tesla rotating field.

Hi Warren,
I think the stator core is OK. It has 12 slots and three phases. It's probably wound as a 6 poled stator having 3 NS-pole pairs. It will have to be rewound to shifting poles if it is to work the way Pierre Cotnoir does it. For six poles in a 24 slot stator each pole takes four slots.
The new windings could take six slots per pole as Pierre's stator does. This will make it a four poled stator. This can then be driven by six phases like the way Pierre does it. When shifting the six phases six times the poles have made one fourth of a revolution and the original north (or south) poles have changed to its opposite poles.

Removed 2.4Mb photo of the stator!
Hi OleIs this what you mean as the thing we might be able to use?Iv'e seen the drawing, but I am not certain what to do next.Please help.Cheers Warren
