Introducing... The Adams Axial

This is a twist on the patented Robert Adams Motor/Generator.

In its simplest form, it is driven by pulsing electromagnetic fields into a rotor holding 12 magnets. The 6 coil cores on either side of the rotor are offset 30deg to form an alternating path for the magnetic flux field to follow, which results in radically reduced reluctance on the rotor. This means I can spin a rotor MUCH faster with much less power than would normally be required.

So far it's been a long, somewhat misguided and bewildering journey, but the end goal of this project is to a self sustaining motor with gobs of torque that can be used to drive a generator. 

Stats so far show me a 2x --- 5x input/output increase between bottom EM coils and top GEN coils (18V in, 80V out), and rectifying the output of the bottom EM coils is returning (depending on hall sensor position) 18-25VDC... from 18V in  Guests cannot see images in the messages.

The beauty of the axial platform is I can also do stupid things on the top coil - like using a diode across the coil terminals to create a spark gap and rectifying (+2000VDC...) without hurting the EM circuit.

The focus now is to drive BOTH sides (all but eliminating magnetic reluctance) and have the EMF generated and recprirocated between the two coils sets.

Very interesting
So do you flip flop the coils that is one side drive the other generates then flip?

[unimmortal]

With both sides being alternatively pulsed, and as I'm following Adams, the coil is charged to attract and when switched off, the field reversal repels.

Getting the right magnet to coil to voltage pulse ratio to maximise the magnetic field collapse and EMF capture is important, but feeding/switching the EMF back into the opposite coils is now the challenge.

[Shylo]

Are your magnets in alternating poles?

[unimmortal]

No, N facing up, S facing down. I've also got heel slugs on the back of the coil cores now that bias the magnetic field formed by the EM to better polarise the coils.

The secret sauce that I'm after is the energy from a magnet having to respond to an EM that suddenly changed polarity. When the EM power is cut, reversal of polarity occurs, the magnet is then in a paradox - it is attracted to a like pole, the response from the magnet is a big negative pulse of energy as it tries to regain equilibrium. So by upsetting equilibrium by injecting energy, the response sees even more energy returned.

Question for ya,

Little off topic, but if you spin the rotor and use it like a generator, does the output produce a clean sinewave? Or is it more like an M shaped wave?

That's gonna require tools I don't have... yet

[Shylo]

If spun like a generator would it not produce all positive humps on the top coils
And all negative humps on the bottom coils and they would be 30 degrees out of phase?
By humps I mean the two halves of the sinewave.

[unimmortal]

Correct. 30° = 180°/6.

Now you can see how this thing is such a chameleon.

By humps I mean the two halves of the sinewave.

Passing a single polarity magnet over the face of a coil produces a full 2 polarity sinewave.  The sinewave switches direction as the magnet passes the middle of the coil.

Each coil will produce a full sinewave per magnet pass.  The phase relationship of these individual sinewaves will depend on the magnet to coil count and the spacing.
