@Collapsing field .That was a very interesting and relevant simulation . Now can you [or anyone] answer this question . What would ne the effect if the ferrite core was lengthened by [a] 25% and 100% . the reason I ask is that i am trying to find out if the length of the core is critical . The main reason is that some people are anxious to work with materials they have easily available .

good question, neptune
(and good point earlier about the possible 'cancelling' effect of trying the coils in series)

i'm planning to mount my coils 'inside-out' which means that my cores will need to pass right thro' the stator 'decks' (and obviously the stator decks will now need to be close to the rotor) to maintain a short gap between core & rotor-mag

some spare core will be used in passing thro the stator deck, any remaining spare will be at the end where the stator mags are placed, so i'm hoping that i won't need to cut off this excess part of the core, since

a) it's away from the coil-rotor interaction;
b) the stator mag adjustment can be used to compensate for the extra 'unused' core at the outer ends

if these assumptions hold, then the the core length becomes less of an issue

it seems like this approach at least gives us another option to dealing with extra core lengths, possibly up to 100% of Romero's

@all. I previously asked Romero if he had tried stationary magnets on the coils down below [lower deck] He is likely under too much pressure to answer me . HE MUST HAVE TRIED THIS , AS OTHERWISE , THE LOWER COILS COULD BE DOING LITTLE EXCEPT WASTE ENERGY . Has he discussed this with anyone else please ?

If you will look at all the videos, especially the one where he suspends it, you will see the lower coils do have the bias magnets on them.

@Romero

Thanks for the inductance.

Can you, pleaae, measure the resistance?

Thanks,

Fausto.

hi again

yes, at 09:38m into the pre-self-running video you can clearly see mags on the lower deck in a low view thro' the side of the rig

hope this helps

Other config with stronger rotor magnet.
