As previously posted.

I think he is using the two relays in the same configuration as a two transistor switch (like a you get in a forward converter).

As the relay coils are isolated you only need one transistor to switch them both.

Hi L192, I understand the image you posted, but it doesn't make sense with the recovery diode configuration Pierre has. In your image only one diode can go back to the voltage supply line (from bottom of coil to +5V). The second diode goes from ground to top of coil. However, in Pierre's setup, the recovery board only has a +5V connection. There is no GND cable and all 72 diodes hook back to the red capacitor bank charging connection on the output of his 4ohms resistor.


I think his windings have a center tap and he is using the two diodes as a full wave rectifier to the capacitor bank, see attached picture (replace the load resistor R by the capacitor bank and forget about the left part of the transformer in that picture. U at the left of the image would be the positive and negative BEMF that occurs over the center tapped coil).

Ok L192

The return wire (red) is relatively thick. But I can't find any black "return" wire relatively thick?  (ground) And Pierre don't mention anyting about that anyhow. So the wiring have to be in another way, Or?

--> pmgr Pierre is using a FullWaweRect. Only two wires into the rectifier!

Hi PmgR,

Looking at his messages on  https://brfilm.net/v-100-free-energy-generator139v-1600watt-dz-generator-part-4-t1abEsE4R3U.html

I see he is saying 6 phases per rotation, so 6 coils on spaced at 60 degrees at any one time. This is how he is achieving the slow clock rate.

So 360/36 =10 degrees per slot, lets say each coil spans 6 slots or 60 degrees

Still 36 independent coils  each turning on and off using two relays, each with independent energy recovery.  The relays in the two switch configuration all tied to the same DC bus.

No series or parallel connection of coils driven by the same switch pair.

Regards

Pick your polarity choice.  B always blue on the right side 1 - 18.

If you look at the end of the stator, the coils don't reenter the stator at the 3 slot point.

The wire bundles move behind and reenter further along. Now it might not be 6 but you can see its not 3.

Something to start....God, I was rusted. lol
I still need to finish.
Also I'm thinking what I need to do with the driver. I do have an old PLC, 500. It is good start. Relay output. I lot to do..

Wow ariovaldo, looks good!... did you rewind the stator coils?

Thanks for sharing

Yeap!
4 poles motor, 1:8 pitch, 2 layers, series lap. Double 30 turns windings of 20 gauge wire ( I do have another tests to do ), 7 hp motor stator.
My last one that i had done was 35 years ago....
Also, I din't have the proper nomex paper, so the stator will not be a class "F" insulation. Lol

L192, can you make a flattened out drawing/sketch of the 36 slots and show how the windings go.  Are you saying each coil still only occupies one slot, just that the return of that coil is shifted by 6-8 and goes over the backside of the slot?

WOW!!!  you are the most dedicated builder I have ever seen in the 10+ years I've been here. I wish you all the best as that's a lot more work to do.
I wouldn't be prepared to do so much without having more information.
Please keep us up to date and let me know if you have any questions for Pierre.
So far Konehead is the only one that has asked which I'm finding hard to believe.

Thanks.
I want to do some tests using a puse dc, rotating as a normal motor. I had used a VFD in a normal motor stator and I noticed some weirds effects when I crossed some wires with a dc load from a battery inside the stator...
I'm just trying to understand that.

Hi PmgR,

I believe ariovaldo has the correct scheme in the post of his 36 slot stator.

He is using a 8 slot pitch for his coils. 

Now as Pierre is using 6 phases spaced at 60 degrees, an 8 slot pitch would cause the phases to overlap which would reduce overall voltage swing, so I believe Pierre is using a 6 slot coil pitch.

If you decrease the coil pitch too much, then inductance will be reduced and hence flux level and voltage swing. 


Regards

Very well done ariovaldo!!
I think no one else is asking, because everybody knows how busy pierre must be, now.  Although he wrote in a comment that he will make a video with all details
.After that I hope we are able to make a replication.
