Muller Dynamo

it apears that the diodes were connected wrong, maybe this was the reason to have it removed
the numbers on the right hand side should start from the right to the left, I think..

Romero had a picture posted then he removed it. Looks very similar with what Bruce is doing.
I managed to save it to the computer before was removed.

thanks for posting this, David - on which thread did Romero post this, before removing it again?

thanks, can you recall if it was in response to something particular?

thanks for doing that test Laurent - fascinating to 'see' the field fluctuating around each core

so far, in the thread, we've tended to concentrate on the vertical effect of the field as the rotor mags pass through the Gen coil-pair gaps

your test, however, shows that there is significant horizontal fluctuation around the core also, which must all add to the overall induction in the coils

the magnetic viewing material only gives a certain level of detail - and of course, it didn't cover the whole circle of the cores - so it wasn't easy to see anything of this 'travelling wave' of magnetic alignment

it would be interesting to view the device again later, possibly driven at slow speed, and with the stator mags in place (if they don't overwhelm the viewing material)

thanks again

What Woopy is showing is natural for the lone core to attract the magnets field, as we see the flux is not much expanded. But with the bias mags, I have a theory that I posted earlier.....

I see it this way.....

Lets just picture 1 set of coils, top and bottom, no rotor.

I think that being the top and bottom are in attraction to each other, when the rotor mag is not over the coils, but in between coils, that this attraction happens and helps to create a flux field band between top and bottom coils. Not necessarily tight, but a band of moderate concentration.

Now we will just look at the top coil and assume the bottom will mirror the tops actions.  ;]

When the rotor mag approaches the coil, we might think that the mag is not attracted to the coil core. It may not, being the core is biased in repulsion to the approaching mag pole. This approach of the rotor mag will most likely push the bias field to the opposite side of the coil core. Now we have the bias mags field cutting the exit side of the coil, and we have the entry side of the coil being cut by the rotor mag. 

This combination could be doubling the amount of flux cutting the coil at that time. Instead of just cutting on the approaching side, and just the exit side when the mag passes the coil.  This may be key to his amount of generation, for such an open and seemingly sparse generator construction, say as compared to any production model considered.
