@Lumen,

RomeroUK lives in London.

I wonder what Latitude Romero lives at? Didn't he say he tried to run it on edge but it didn't work well?
Is it possible he lives around 45 degrees north and the Earths magnetic field plays into this somehow? Maybe it directs the Earths field through the cores for the added energy gain?
I guess if someone gets it working it could always be tested in a magnetic free environment.
Just something to think about for those building with a vertical rotation plane.

Lumen, The way I took Romero's comment was that his bearing arrangement relied on gravity for proper alignment or in other words, the shaft was not captive? I think

It could help understand the role of the parts.

Note the rotating field vortex forming in the coil cores. "Regauging" with stator magnets rocks.

Magnet biasing a pick up coil could reduce cogging but changes inductance factor.

The performance of a pick up coil (generator coil) depends on

- the number of wire turns (more turns need thinner wire, less amperage),

- the size of the coil (its dimensions also influence the possible number of turns),

- the core material (its inductance factor, its dimensions),

- the gap in between the passing magnet and the core of the coil

- the strength of the passing magnet

- the speed of the passing magnet

If all this is chosen right, some optimum of performance will be achieve.

Putting a magnet near the coil (at the outside) will change the inductance factor of the core. If the inductance factor was right (i.e. achieved an optimum) the performance will drop. If the inductance factor was not optimal, the magnet could cause a performance gain (by correcting the inductance factor).

The more tricky effect is the cogging: more cogging needs a higher force to drive the generator. So, if the magnet reduces cogging there could be a gain in the sense, that less force is needed to drive the generator for the optimum output of the coil.

In short: the benefit of the magnet could be the reduction of cogging as long as the change of inductance is towards the optimal inductance and not away from it.
