Explanation

The field coil being fed by the battery is constant is it not?
If so there is no growing and shrinking of the field.
The generating coils are seeing full on South then North almost instantly.
I think your adding alot of complication by trying to gradually grow and shrink.
I think you just have to flip the coil input to create a alternating field
Just way I see it maybe I'm wrong.

I think your idea could be tested with original alternator/generator. But u would need to make some mechanism for rotating brushes around commutator of rotor while your rotor would be stationary. Interesting would be to see what happens when u rotate brushes instead of rotor Guests cannot see images in the messages. Please register at the forum by clicking here to see images.

In an alternator- yes they are constant fields.  But they are physically spinning.  Which yes they are growing and shrinking as the poles come closer and further away from the coil. If we just flip polarities we become a transformer. 

Transformers output is not enough to sustain the magnetic field that created the energy.  But a generator DOES output plenty to sustain the magnetic field that created it.  (because of physical rotation).

The idea is to exactly match how the rotor spins without motion.  And it follows the inverse square law.  I think capturing the growing / shrinking is extremely important.

edit...  This is an interesting idea...  Need to experiment

I gave this some thought and tests.  Problem I see with this is that all the coils are always equal intensity.  It does rotate, but we get no pull away or approach.  

Excellent idea though.  Perhaps it can be tested and developed

So doing a new build on this..  The reason an alternator can sustain it's own magnetic field is because 1/2 the wave the prime mover becomes reactive and it able to send back to the battery. When we make VRMF's with electronics, we need to use all sorts of crap that eats away that reactance.

So what better way to create a perfect rotating magnetic field than actually rotating a magnet..  Figuera seemed to have done it with 8 phases, so I am sticking to 8..

1.  I am making an 8 phase generator..  A 2 pole magnet rotor will rotate inside 8 coils.  Each coil will be separate to get 8 individual phases.  The magnets on the rotor will be very powerful and big so the phases overlap.    

   

2.  I took a washing machine motor stator that has 8 coils.  Carefully separated each coil leads and wired it to terminal blocks.

   

   

3. Each phase from the generator will connect to an individual coil in the stator.  If I get it right, it should give me a perfect rotating magnetic field inside the stator.  

4. Finally, an output coil will go inside the stator.  

We will see!

Wow I did much experimenting to gather data.  Trying to determine the exact parameters of rotation that send current back to the battery. We can make virtual rotation with many phase options.  

So first I tried 2 phase. https://www.youtube.com/watch?v=eJakzUTFlBQ   <---  Nothing sends back to the battery with 2 phase.

Then I tried 3 Phase.  Again- Nothing!

Next I tried 4 phase.  Viola- some starts sending back! But we need an increase of it..

My conclusion is, the back EMF created can induce slightly above the input voltage of the highest coil at any given time.  Maximum. So the voltage of the rotating coils matters immensely. because we have to consider the potential difference between the two.

Lets say we use 2 phase at 10 Volts.  High coil is at 10v while low coil is at ZERO.  Back EMF is produced that sends 2 Volts to each coil.  So high coil may get to 12V and, but the low coil also only inducts 2 Volts, so it is at 2 Volt.  2 Volts can not send current to the 10V source.  3 Phase is even worse!

Now lets say we used lots of coils.  Each coil was 1/2 of a volt lower than the previous.  Now 3 or 4 coils will get enough induced potential to return current to the source.

The point is, we need to keep the phases really close together.  This must be why Figuera used 7 or 8 phases.

As an example-  position 2 pickup coils and  driver coils.  And induct 5 volts into the pickups.  Now bias one pickup with 10 V, now one pickup will have 15V because of the difference in potential that was already present, and the other will have 5V.  If the source is 12V, only the 1 coil that is at 15V can send back to the source.

Took all day!.. But I think I got it nailed down.

8 Phases.  16 leads.  Like an 8 cylinder engine!

Tomorrow I will test!
