Romero said that others needed more capacitance in their coils. One way is bifi. I posted that after romero's post and he verified that fact. True or not, I cannot say.

Are your coils easily removable as to change up later?  If so, good.

Some suggest that he may have had shorted coils involved as his experiments just before this motor were involved with shorting coils and increased distance from the rotor magnets.

So if after testing with what you have, try a couple turns of shorted windings on top of the existing coils to see what happens. With only few turns of shorted windings the drag should not be much as compared to shorting the larger winding with a magnet pass, but might influence the larger winding in a good way.

Just some things that I remember from back then. ;]

Good luck. Will be watching. ;]

Hi Mags,
I've been doin this for the past few months still no results so far but I'm still trying    I'm not doin any other project just concentrating on this one until my patience leaves me lol!

My coils are easily removable, for now, because they are just air core coils fastened by plastic bolts.
Might still go back to magnetic cores later but, for now, trying to keep it simple, and cheap, and reduce Lenz effects.

With regards to shorting; I wonder if anybody has tried just shorting one, or more, conductors of the litz wire?

Hey Scorch

Romero used cores and did it work?  ;] The core attracts and concentrates the moving field on the approach to that side of the coil only and then the same but reverse order as the mag is leaving the core and heavily 'cutting the other side of the coil.

Air core works to an extent, but is weaker and no control over the density of flux on 1 particular side of the coil at a time.

At high speeds, the advantages of output should exceed the drag of the cores.  ;]

Look at the wave forms. Up coming in and down going out( or down then up depending on polarities), one side produces current in one direction in the coil that the other, the opposite. Air core is better if the 'sides' of the windings are separated more, like a window motor. When wound in tight diameter, the air core will allow a lot of flux from the mag to be 'cutting' both sides of the coil during most of the pass, causing less resultant output. The magnetic core is a barrier of sorts to isolate the left side of the winding from the right side, and thats why we get more from a coil with a metallic core. ;]

Wont hurt to just add a couple turns shorted on the top of the existing winding to see what happens. ;] Take it off if no go. ;]

Bah,  you guys are champions. ;]  I wish I had the time and less existing projects so that I could do many other things. This is just not one of them yet. ;] Its on the list. That big ole list.  Ugh.  ;]

Imagine a few or more turns wound then shorted on top of the many regular windings. As the mag passes, the shorted coil will have much more current flowing than the regular winding. It should act as a primary of a step up transformer and produce higher voltage in the regular winding. Just theory. ;]

excellent thinking mags I recall the videos about shorting the coils that people were trying to do to see certain effects but I think this has yet to be attempted nice outside of the box comment +1
