Introducing... The Adams Axial

Progress! Looking good, inimmortal!

I think that machine of yours needs a nickname.

I think that machine of yours needs a nickname.

I should have mentioned that if I put more coils to pulse from outside the rotors, I'll get double from the gen coils, and if I fill the remaining rotor slots with opposite polarity magnets, it'll double again.

It's a little monster.

The build continues... after watching a rotor try to be in two places at once, I bit the bullet and have a shaft and mounting hardware on order.

I'm busy rolling 12 identically weighted 0.5mm wire coils onto 37x20mm rounded thread sleeves. I've since found out that Robert Adams also used bifilar between his generator coils to hold up the collapsing magnetic field, so that's a nice correlation with the aboveunity folks.

I've mapped out the build onto a whiteboard, so it's a little easier to understand all the moving pieces. Pulsing can happen at either or both ends, but they will alternate. The green output is the flyback circuit that I'm hoping I can use against itself (alternating, top and bottom) to draw additional current.

Incidentally, from a 14w input this now puts out around 300V of potential... with all 4 sets of generator coils connected in series. Setting the bias capacitor 'should' have two north poles facing each other sustain the magnetic field long enough to draw current from.

When overkill is underwhelming...

Below is the latest iteration of the build. Pretty much as per my last post.

The 4 generator coil sets are putting out 35.5V each and are nicely balanced as I'd hoped. A little disappointed with those numbers, as the power consumption is floating around 20w (0.5A) now that it has to drive through 12 20mm cores. The 3mm ally FET mount does a good job of also playing heatsink.

Next step with the gen coils is to wire them into a bucking coil arrangement. I still also need to mechanically switch them, which 'should' drop input power.

For the keen eye, you'll see a diode hanging off each black wire (4), which is handing back a differential of 47V against either the diagonal or adjacent pulse coils, but zero with opposite coils - expected as the opposites cancel.

New shaft is a God send, but at 300mm I've run out of rod to mount a commutator. More things to get..

And lastly, the simple coils between rotors build (150V from ~15w), that triggered the latest build.

A quick update and video after a day of scratching my head.

I believe I've upset the balance with the offset coils, which while all but eliminating cogging, introduces a doughiness due to a lack of air.

So I'm back to pulsing half the generator coils between the rotors. Interesting a power supply in standby gives me 2V from one half of the generator coils. Seems there is resonance.

[unimmortal]

Right, keeping the momentum going, I've reconfigured to focus a bit more on the generator coils - there are now 3mm of spacers between them to give the fields a little more space to form.

I'm pulsing from the ends, with no offset on the generator coils giving me 3 x 1 foot magnetic columns. 

There is still fine tuning to do to level voltages and so on, but the potential outputs are looking favourable. I can't give a series connection voltage as the fields being more fully formed are resisting connection.

The balancing act is starting to show itself.

(Here's a quick video of a configuration that normally would put out +60V per coil set, however the opposing fields are fighting to grow, which means they'll fight equally to shrink)

[unimmortal]

Well here's a conundrum;

6 pairs of partnered coils (CW bottom, CCW top, wired into 4 sets of 3. Multimeter leads are across the outside windings of the 4 coils sets. 

Rotor mags are both N up.

When I join the top coils sets via the inside windings, I am somehow then able to get a reading from the bottom coils sets even though they aren't connected, and vice versa.

Each partnered coil set is joined via 13mm threaded rod, so a flux path exists.

The top coil set is re-gauged, that is, wired for the opposite direction the flux prefers to flow. 



Anyone make sense of this?

Impressive build. I know people make a big deal about CW and CCW, but my experience tells me it doesn't matter.

Thanks man.

Funny you should say that. I've just sat down after a morning of testing. The potential I've found is across alternating CW and CCW coil (sets). After blowing out a few 12V globes I'm up to 21W brake light globes. Hooray!

The CW / CCW coils are wired so they both create north facing fields, both resisting each other, and thus sustaining the magnetic field that then continues to induce current.

Connecting a globe sees the meters showing a jump between CW and CCW where one will jump a few volts and the other shows the coil being  monstered and drop of quickly.- so I still need to introduce something to balance the two.

Switching generator coils has been nothing short of a f'ing nightmare,  but, I did get some results. With my older meter, which can see the negative spike of a switch open event - I was able to repeatedly take if from -20 to -200V by switching one and then both CCW coils sets wired together. My DMM showed voltage go from 75V to around 100V. A scope will show the true story, but very
encouraging.
