Butch,

I found a design that you apparently already made that looks exactly like what I had in mind, in January! Dang, thought I beat you too it. ;) How did that cog-free design work out (on a FDP website)?
I conform to non-conformism.

Any new news about people's builds of the LG switcher?

Hi all.
I did some tests with my resin and metal particle core but it was not much good.  :(
Because of the random structure of the particles, the flux did not want to run through it very well. Even though it's magnetic enough, it does not make a good path.
I used a stack of neo's on the end of a section of my core and after about 3 inches the flux is almost gone, and it could not even attract an alligator clip.
So in my core the flux wouldn't even make it to the coils!
Anyway....it was worth experimenting with just to see.
Scotty.

That's too bad Scotty. I think I missed the point, but would a normal ferrite toroid work? Well, two huge toroids with different permeabilities? I found some on a website that can be ordered up to 9" OD.

I was going to drill holes for ferrite rods as well, but I'm scared even with my carbide hole maker. Lol

I think this device may have some exciting possibilities.  I'm thinking of doing a parallel path on the stators, doing the iron oxide with epoxy resin approach plus doing them with silicone steel laminations.

  I've found several India/China sources that will do it all for you but seem to be more production oriented.  I would like to just procure the steel and then have them laser cut locally but can't find any suppliers yet.  It looks like silicone steel is available down to .014" thickness with varnish insulating coating but only in production quantities.  Does anybody have a supplier for silicone steel in prototype quantities?  Also known as transformer steel or lamination steel.

  For the iron oxide/epoxe resin version, will experiment with magnetically biasing the oxide particles when the resin is poured.  This hopefully will increase the permeability of the stators.

  I'm wondering if the radiused end caps at each end of the magnets on the rotor should be done with laminations or resin.  I would imagine unwanted eddy currents would be created here as well.
