Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Post subject: Non-contact power transfer with air-cored transformer? Posted: Wed Nov 02, 2005 7:08 pm
I need to commute power thru a coaxial rotating joint (with 100mm hole thru the middle)
Does anyone have any advice for calculations?
Presently I am using 5Khz and can transfor about a Watt but need to scale this up to several Watts.
