Here is some data for anyone interested.  It is input and output measurements on the 3 single filer coil pairs run in parallel to the dump cap with various loads.  All measurements were taken with the same DMM.

Your output is really low compared to input... Maybe that's because of the motor you're using. It's in the center of the rotor. So the force applied by your motor at the center is not strong enough to beat generator coils bemf.That's why it can draw more power.

There is only one macroscopic vector inside a standard magnet.

The magnetic field measured outside a magnet in the center may appear weak compared to the end-pole locations, but this is not because of any vector cancellation or equality. This area does not constitute a "Bloch Wall Region", despite any general misuse of the term.

It would be a true shame if "real-world" EE's contributed to this misnomer. But, as most may not be well trained in magnetics, this is a possibility. Don't take this the wrong way, but I would expect (and hope) that anyone working in magnetics as a profession, or as a serious researcher using magnets and ferromagnetic materials, would be better informed.
Call it a "neutral zone" if you wish, but it should not be called a "Bloch Wall". This only perpetuates the misnomer, and facilitates a misunderstanding of the magnetic field in and around a magnet.

Put simply, I disagree. Mostly. LOL

Do you disagree with the fact that there is one vector (one magnetic moment) inside a standard magnet?

No.

The homogenous vector within a magnet that is not interacting with anything is of no consequence.

It's not doing anything, when it's all alone 

But as soon as you tap into its field for whatever your purpose, you are introducing an external parameter, that introduces added vectors.

It is precisely how the magnets external field reacts to and influences this external parameter that is of significance.

Once an external element is added, it may be nearer or farther or equal distance from N or S and the vector between that element and either pole will determine whether it is attracted to one greater than the other or experience a net pull by neither of them because of their equal attractive force.

It is the vector interaction between the magnet and element that matters when designing something like .... hmnnn a muller generator perhaps.

Simply by putting a core next to a magnet, they will both influence each other in terms of how they will "see" each other.

Right now the coils are quite far from the rotor.  I will begin moving them closer and repeating these tests.

The input I am measuring is to the entire motor drive circuit, not directly to the motor.  That circuit includes a variable regulator to provide 0 to ~14V to the motor drive IC.  The input is also powering a separate 5 V regulator that provides a CTL signal (on signal) to the motor drive IC.  The motor drive IC itself (Mitsubishi M568732AL) is also, of course, in the circuit.  So all these extra devices and their associated peripheral resistors are wasting some of the input energy.

This system is not as input power friendly as those with pulse motors I am sure.  But it gives me good control of the RPM in case that is an important variable.

I am focused on the generator side of RomeroUK's setup only.  I don't believe the drive side is where the OU effect could be found.  Of course the drive side power requirements are important if one hopes to loop.  And I do wish to loop since that is the only proof of OU many could understand.  So I am looking at the relationship of the output to drive circuit input on this system to try and determine if my coils are designed with enough output to even consider moving forward with adding additional coil pairs right now.
