Hi Kone,

I don't think it matters much if the coils are spanning several slots or being split up into smaller coils between two neighboring slots. What matters is mixing the magnetic fields into coherence which represents more energy than single coils added do. I'm preparing an experiment using small ferrite transformers instead of a motor stator. You know from your forum that I like doing the experiments in small scale as electronics are scalable. It looks like Pierre's device isn't depending on resonance as the load can be changed without affecting its running. This is unlike the Jensen UDT and Hector transformer that both are affected by changing the load and both have to be fed reactive power for overunity. Pierre's new winding is more like Bob Boyce's way of putting poly phases into a single ring core. Tesla also did that in some of his patents. This forms rotating poles extending out of the ring core.

Pierre's first stator has the magnetic fields in parallel while the current is in series. This makes the stored energy coherent and makes the stored energy increase to the square of the current. In his new stator the magnetic fields are in series and the current is still in series I guess. The field through the blocked rotor core may still be in parallel and thus could become coherent. I.e. the field from two neighboring similar poles may become mixed into a coherent field representing more energy than the single fields added before being mixed. This is the principle of inversion of Wilbert B. Smith.

I'm currently designing only six bridge outputs for running six transformers which probably is the smallest number possible if it has to work like the device of Pierre. Pierre's device has some of the coils shorted which makes them act like permanent magnets even though having loss because of the resistance of the wires. It can be made simpler if the coils don't have to be shorted. Perhaps I should prepare for making it possible to switch between shorted and not shorted coils. The non-shorted coils will demagnetize and 'discharge' to the voltage supply rails through the parasitic diodes in the MOSFET outputs.

By the way people should also know about the Molina-Martinez (https://patents.google.com/patent/US20030168921A1/en) and Hyun (https://patents.google.com/patent/US20040007932) patent applications. They both claim overunity from ordinary three phased rotating fields and even from two phased fields (Hyun). They both use a locked rotor as secondary. This makes it possible to use a standard stator without having to rewind it by feeding it with three-phased AC. I haven't seen proof of this concept before the Pierre Cotnoir device.

Ole

Hi Onielsen,

I posted a picture of a Hyun replication in the other thread, for the simple two phase device. This one did not yield a positive result, as the shaded pole technique consumed too much power.

I tried a linear version of the three phase transformer (picture also posted) however, this did not develop the traveling wave component, so nothing special there.

I have the facility to cut silicon steel lamination's now, so it might be interesting to revisit the concept and cut the circular infill section required to complete design.

The rotary flux transformer only needs a VFD  to work, so a much simpler build with a good sine output.

Hi MenofFather,

Several theories have been tabled in this thread but I would say you need to rely on your own belief in a theory of operation.

If you don't believe that this has at least a 50% chance of producing a favorable result, then don't attempt a replication, as there is a lot of work and cost associated with the build.

Some people need> 100%, sometimes it is not enough.
They wait as it will be in the store.

BUT now I am confused (as is usual) and watched Pierres most recent video (part 2) of his 10hp size stator, and he is now winding the coils on it very much different than his previous DZ generator (it seems) as now he is doing it straight across the core more or less rather than skipping over 5 or 6 slots as before....
So what should I do?

Same question here. I just received my 3phase 4KW scrap motor. I still need to salvage it so i have some time to think it more. The new topology will experience 100% the transformer effect between primaries, but this is not necessarily a bad thing if someone count it and raise the input voltage.

How many slots ? I need 36 like Pierre.

I will answer you in two days, as due to the holly days i have no time for this right now.  ;)

" pierre Cotnoir
    one day ago

I only rely on the operation of a generator the rest comes from the logic how the magnetic field interplay test and error

all does not work as I want it sometimes , like the new prototype

I have no idea if it goes to work


but one thing is sure if you have an idea and you do not put it into practice it will never work."

36 poles 5,5KW
I see that there are some wedges circumstantially placed between stator and housing. Should i hammer them for extracting the stator out?

Take it out of the housing and remove the wires. It took me 4 hours, I did it for the first time as probably you. Good luck, it's hard to do.

My rotor is different. It's from a generator.

Just like my rotor the overlap is a lot more than 6 stator poles, about 11 on this one and about 9 on mine.

Pierre looks like he has a custom rotor, as his covers only 6 stator poles.
They could be trimmed down to 6 poles, but  a bobbin edge would have to be created to hold the windings.

Hi L192,

Maybe it has a core from the welder or sheet metal packaged.
Yes 6 slots size.

This video have different magnetic poles arrangement. This time the resulting magnetic polarity will be on 90 degrees from previous setup.

Still interesting to see if he will be able to make proper induction... ;)

Cheers!

How did you extract your stator from motor's housing? The outer casing looks like an iron cast.

Just push under the press or cut.

If anyone thinks this is an easy build you better think again. Winding a stator is only 25% of the job. See below video of my finished product. Testing will begin tomorrow after winding the center core.

Fr. Si quelqu'un pense que c'est une construction facile, il vaut mieux réfléchir à nouveau. L'enroulement d'un stator ne représente que 25% du travail. Voir ci-dessous la vidéo de mon produit fini. Les tests commenceront demain après avoir enroulé le noyau central.
