Hypothesis on the Clemente Figuera Principle

[nagual]

This is another possible principle I inferred based on the Clemente Figuera device.
Consider an EI-type three-phase transformer core where the cross-sectional area of the center limb and both side limbs are the same. Electromagnet coils are wound on the left and right limbs. When energized, the magnetic polarity in the center is aligned (N–N facing), and the center limb contains the generation coil.
Using this method of power supply, the following effect is produced:
Assume that initially the right electromagnet generates a magnetic field of 100 units. This flux splits and flows toward the center and toward the left magnetic path, dividing equally into 50 units each. The left side is recorded as −50.
During time interval A:

• The right electromagnet decreases from 100 to 50.
  
• At the same time, the left electromagnet increases from 0 to 50 toward the right.
  
• Both magnetic paths direct flux toward the center.
  

During this interval, a reversing magnetic field occurs. The magnetic flux in the center limb increases from 50 to 100, producing a downward counter electromotive force (back EMF) of 50. This effect may primarily act on:

• The increasing coil on the left side, reducing inductance
  
• The decreasing coil on the right side, providing cancellation
  

In this interval, the energy behavior may be:

• Left side inputs 50
  
• Center outputs 50
  
• Right side recovers 50 (either energy recovery or delivered to a load)
  

Then in time interval B:

• The left electromagnet continues increasing from 50 to 100
  
• The right electromagnet decreases from 50 to 0, and is charged to −50 by the left side
  
• The central generation coil is now fully driven by the right side, decreasing from 100 to 50
  

After that, the system returns to time interval A, but with left and right reversed.
My hypothesis is that:

• One side undergoes discharge (or any process that reduces the magnetic field at the same rate as the other side increases), such that both contribute equally during the midpoint of the time interval, maximizing the magnetic field in the center limb
  
• The other side undergoes charging
  
• The back EMFs of the left, right, and center interact with each other
  
• The center simultaneously influences both sides, but in opposite directions
  

This resulting asymmetry may make the system feasible.

For this type of principle, it’s unclear what the optimal driving method is. In general, the rising and falling edges should have the same rate. The falling edge might allow energy extraction (or perhaps not?). What do you think?

I congratulate you making a magnet flux diagram in the core.  Most people are unwilling or unable to make this type of drawing.

You should analyze this magnetic circuit using the Hopkinson's Law.
This law is like the Ohm's Law for electric circuits, where magnetomotive force (ℱ) is used instead of voltage (V) and reluctance (ℛ) is used instead of resistance ( R ) and magnetic flux (Φ) is used instead of current (i).

Ohm's Law:  i=V/R
Hopkinson's Law: Φ=ℱ/ℛ

Note: Magnetomotive force (ℱ) is measured in amp⋅turns. IOW: it depends soleley on the number of turns of your coil and the number of Amperes flowing through these turns.

There is a significant difference though because anytime electric current (i) flows through a resistance ( R ) it is dissipated as heat at the rate P=i²R .
However when magnetic flux (Φ) flows through a reluctance (ℛ) it is not dissipated at all but stored as magnetic energy which under ideal conditions can be entirely recovered.
The legs of the core you had drawn act like 7 reluctances in series & parallel ...and air is a reluctance, too.

The magnetic energy (E) stored in a reluctance is:
E=½ℱ²/ℛ
...or
E=½Φ²ℛ
...or
E=½ℱΦ

Also, it is useful to remember that inductance (L) is simply a ratio of magnetic flux (Φ) to electric current (i). In mathspeak: L= Φ/i
Bacause of this, the energy (E) stored by inductance (L) bearing a current (i) is:
E= ½Li²

Hello nagual,

do you think that device figuera was driven by the power supply or was it driven by the rotation of the brush? Or both, each affecting something different in the same device?

A rotary generator includes a field current regulator to maintain a constant output voltage, it is a small change in DC voltage that keeps the field coils excited (P=I²R losses) by tracking the output voltage. Picture 1908 shows a brush with a DC supply. Could the magnitude of the DC voltage do the same?

And brush? Exciters work with current and with magnetizing energy. You choose heating or energy recovery. 

Source website: “A forced oscillator is a system that oscillates under the influence of an external periodic force (or voltage), not only based on its own (natural) oscillations. The external force supplies energy, thereby compensating for losses due to damping, and thus allows oscillations to be maintained even in real systems that would otherwise stop. “

I think as long as you keep the left and right legs of the magnetic core moving such that one rises while the other falls at the same speed, it should work. As for the specific type of power supply to use, I’m not entirely sure.


~~~~~~~~~~~~~~~~~~~~~~~
As for the straight-line configuration that most people seem to copy from the manual, I haven’t seen a single successful example. In that setup, the generating coil and the two electromagnets are aligned in a straight line, and the back EMF acts on both electromagnets simultaneously and in the same direction. It’s somewhat similar to a push-pull transformer, except that the magnetic core is not closed, and the windings are placed above and below the electromagnets rather than overlapping on top. Overall, though, I think they’re quite similar.

It is possible for the magnetic flux generated in the left leg and the right leg to vary in time in the manner you are describing and in such way that the sum of these fluxes stays constant in the center leg.  Φa + Φb = const

The variable resistors created by the electromechanical commutators seem to be constructed in a way that facilitates such flux distribution.

This seems like the typical patent maneuver that covers many coil orientations for legal purposes but deliberately suggest an arrangement that is not productive - a poison pill for competitors.

The all-parallel winding arrangement (like on the three vertical legs of your core) is much more promising when flux movement is considered - especially when the horizontal segments of that core are deleted and made into air-gaps - like in this sim's left and middle sections.
