Title: Non air core coils.
Post by: Dark Alchemist on June 25, 2012, 04:28:20 PM
I haven't kept up much with the changing world of cores so I started to look around and noticed something new to me called Amorphous metal.  This stuff is pretty darn nice and I would think would help with anything that has windings.

I am not, and have never been, a fan of open cores for anything less than about a megahertz and if your wind turbine is spinning around 1 million / # of magnets per second then I gotta see it, lol.

Anyway here is some technical info about this stuff (it seems China is already converting their grid over to it): Technical advantage

Where typical ferrite cores can only operate up to a flux saturation level (Bsat) of 0.49 Tesla, an amorphous metal core can operate at 1.56 Tesla. Combined with operating at permeability similar to high-end ferrites and the flexibility of manufacturing large cores sizes these cores can be an ideal solution for many of these components.

What do you think of this for cores in our windings to help produce even more energy or at least reduce or magnet counts (the most expensive part I found)?
