Hi Jim absolutely amazing work on this! Not to mention all the complexity of the wiring and programming too! I've got a question for that power supply you are using you noted the amperage did not move and in some cases went down a tiny bit. If you got a spare wall plug watt meter you could plug that power supply into it to see the watts consumed. I don't have one of these power supplies so maybe I am wrong here how it works but do they keep a steady output where you can adjust the amperage too? Just wondering if the overall consumption does increase and will be picked up on a wall plug watt meter between the wall socket and the power supply. Sorry if it's a silly question! Very nice work though and really excited to see more on this!!

If an alternator can draw 4 amps into the rotor and make 90 amps output, (which they can)  we should be able to virtually rotate the field to achieve the same effect, but with no Lenz Drag because nothing actually moves.   That's basically the idea.

I did off camera.  Problem is, electrical steel usually has a maximum frequency before efficiency starts dropping.  Somewhere between 350-500 Hz things start to change.   The complexities that introduces would add too much confusion at this point.  I actually did upload a video going super quick and the output was even better.  BUT I ended up deleting it because honestly, I am not ready to open that can of worms till I understand this setup better.

Nice work Jim!

I wonder what the wave form would look like in a 3 phase Wye or Delta stator.

Maybe..  12 H-bridges / 24 contacts.  it delay's the specified amount between each contact jump.  I will be investigating frequency later tonight or tomorrow.  Calculating ain't my thang. LOL...

I wish I mad more varieties of stators and armatures to experiment with.  I am hoping I can find a way where it's not needed.

I can test this..  I can also run it off a 12V battery while measuring current draw.

My current thoughts are, if the input does not raise, I may be able to create "Extra Gain" outside the stator..  I did a quick idea test last night and the results were provocative.  

I have built similar circuits before and I can't let it get too sloppy. Things start shorting out and blowing up parts.  And honestly, I am not the neatest person. LOL  So I must take some care here with the circuit.

Figured I'd share a hint...

Soldering to a commutator can suck.  The contacts are hard to heat because of the amount of copper,  and the spaces between contacts are small.  If solder flows into the spaces between contacts it can easily bridge 2 contacts.

So how I did it was shaping the contacts with a Dremel.  Wear a mask and shape the contacts with a carbide disc so each contact is the size of a wire where you will solder.  This makes the gaps between contacts Much Wider and and the copper contact easy to heat and solder to.

Think about using Solar Tabbing Wire.  It made the job so much easier.  Silver-Tip the tabbing wire, heat the copper contact, then align the tabbing wire on the contact and hold the iron on till the solder flows.

You can finally solder your connection wires on to the tabbing wire and heat-shrink it all up.

I think I am maxed out with the current armature and stator.  So I am trying new coil arrangements with the same circuit.

This holder I printed is on a soft steel bar.  It measures roughly 120mm in length.

   

I am going to wind 1 large coil with 2 ends and 10 center-taps.   This circuit will make the magnetic field in this oscillate back and forth.  Then wrap the whole thing in a coil to draw output..

I have many more switches on the circuit, so I can later use them to smooth the field nicely (I hope)

The 12 primary coils have been wound.

21 ga wire,  100 turns per step.  12 steps = 1200 turns.

   

Next to wind an output coil over all 12.  One nice big output coil.

The firing order will go like this: (for the first attempt)

Light up half the coil, tap 1 & 7
move back 1 coil 2&8
3&9
4&10
5&11
6&12
7&13
Then reverse step by step back to start.
Repeat.

This method should move the magnetic field back and forth inside the coil like a shake-charge flashlight.  

But this isn't the only firing order possible.  I have another one in mind also that I may try.  

It should be interesting tests whatever the outcome..

If it is unclear what I am after, this image should clear it up..  It shows the basic firing steps

   

Secondary is wound.  I stopped at 650 turns of 21 ga.  I could add more if the results warrant it later.

   

Now to wire it into the circuit and program the code.

Essentially it is a solid-state Shake Flashlight setup.  LOL..  

Maybe we will have results today

Well, results sucked..

tinmans rotary transformer used only 1 side of the stator to run the rotor and used the other side of the stator for output. same universal connections for rotor and half stator.
