Hi Folks,

On pure iron: You have to consider eddy losses in it so some kind of thin sheets from it i.e. lamination-like pieces are to be obtained if they exist. But then the price may reach or pretty much exceed that of metglas.

Ron, keep up the excellent work.

Lol yes I made a 3000 rpm generator once with solid steel cores. 10mm spacing between the cores and the magnets, and within 2 minutes the cores got over 80 degrees Celsius. Eddy was strong in this one... I never really use solid steel for cores anymore.

LOL, a learning experience!

Thanks for the great response, just going over some of the old posts, brought back memories, some good posts there, even some from Jack.

Researching "pure iron" and seems to be good stuff for what we are doing here. CMI magnet iron would be nice, 99.45 Fe, .028 Mn, .02 C
(ASTM-A-848)

Anyway will be involved with Christmas for the next while, so not much in the way of posting from me for a few days....

Merry Christmas All

Ron
