I wonder how much energy is consumed manifesting the temporary
depolarization cycle.
Bingo. What if that consumption is significant even when the rotor is
not present? How circular is the BH curve for that material?
I could imagine a situation where the core's nonlinearity is just right to
create a weird artifact: the VI drive waveform remains about the same
whether the moving magnets are present or not, and the magnets get driven
forward, and if magnets are being moved, then the core doesn't suffer as
much heat loss as it normally would. Remove the rotor, and drive VI
curves don't change. But with the rotor gone, the wattage goes into core
heating rather than doing work upon magnets.
If true, then the rotor would APPEAR to extract zero energy from the drive
circuit. The result might be to drive some FE enthusiasts crazy with
dollar signs dancing before their eyes.
Remember the "Butterfly" circuit on Keelynet, back around 1992? It
demonstrated a vaguely similar phenomenon (adding a load did not result in
increased drive wattage.) It was based on transistor switching and
decaying RF standing waves trapped in long coax. But drive and load were
completely decoupled, so if the load was removed, the drive wattage stayed
the same, even though it all went into wire heating. Not FE, just a weird
artifact.
To cut through the illusion, just try to close the loop. The excess energy
APPEARS enormous, so if it's impossible to close the loop, then something
is bad wrong with your theory.
