Thane Heins BI-TOROID TRANSFORMER

[Mavendex]

I was going over your hypothesis there and thats alot like the conduit I posted a couple weeks ago, rodin style transformers are cool unconventional winding is great. All you would need is two nanoperms wound up in the unconventional format. Large for the rodin style,  small for your helical or geometric shape, theres a few configurations that work very well. and a few that are bleh.

Should review how your flux paths work in such a model gotta remember that a magnetic field travels 90 degrees and its the completed path that makes it work.

all in all the smaller nanoperms would cost you around 100 a piece, and the tube it self would be rather inexpensive probably could pickone up at menards or home depot. Its time intensive. I tried a couple models like that a year or so ago, the output is nominal but not terrible.

The version I am working on consists only of toroids, no steel shells or anything like that. Toroid material can be anything but I would prefer higher permeability material so that less turns are needed.

No rodin for wiring, only 3d bifilars using Litz. There are many ways to make 3d bifilar and I put something that could work better than plain 2d bifilar. With Litz it is easy to test different variations without tearing windings apart so I just propose something that look interesting/weird.

I recently looked at some guy that compared starship rodin to conventional rodin and starship rodin was better. He put a magnet inside and watched it spin. There is also sun flower rodin, number of points is prime number so when it is wound there comes vortex automatically. Starship/sunflower rodin is much easier to make. But maybe these rodin coils and it variants work better with higher frequency signals, haven't studied this and just quessing here.

stars-hips aren't bad easier to build, there is a reason starships are better than normal Rodin, Ab-ha by Randy Powel or look up jack sholze if your looking to make a bicycle motor.

but those are just normal rodin coils, 18 turns... the Abha Rodin coil you can pulse the coil, watch your magnet spin, turn off the coil your magnet will keep spining, walk across the room with the magnet and the coil off, and the magnet will keep spinning for a good long time.

Its alot of study, and well worth the knowledge cause it can be applied to solid state. Beware it can make you a little crazy

You can't do that with the starship, nor a standard rodin coil, you actually create a vortex instead of a psudo vortex.

Apply that concept to solid state and well thats a winner.

When two flux of opposite direction are in the same core, the net flux tend to be zero...

In the outer path the flux is zero, (but not mean any energy in this core !!!).

At the coil (sec1 or sec2) will remain only the primary flux but BEMF of the two coil fighting itself in the outer core, I have tested with FEMM: between the outer and the inner core should have an air gap, if not then the BITT don't work properly...

[SchubertReijiMaigo]

This BITT have two distinct core: one for the primary flux and another one for the two secondary...
You will see that the outer path have no flux...

Primary was saturated at 50 ampere/turns ( to increase reluctance and increase reactive current at primary side).

Secondary fighting each other 39 ampere/turns... IF you read this topic Thane (cranky pant's speak about a "air gap" between the outer and inner core...)
