Re: Heating in 4-1/2 turn inductor
From: rborowiak@gmail.com (raypsi)
Hey OM:
First how many newsgroups do you have this thread cross posted on?
Second: A 1/2 turn is equal to 1 turn in a pot core so 4 and 1/2 turns
is the same as 5 turns.
Lastly OM: I think you are looking at a classic case of proximity
effect.

Several years ago while making inductors for tuning a class E amplifier we
end up with a 4-1/2 turn inductor. The inductor used a 3F3 potcore, gapped I
think,
but it has been awhile. The inductor was driven hard but below saturation..
The problem; the 1/2 turn got HOT. Four turns or five turns were ok.
My physicist friend had an EE verify the problem 2000 miles away.
So, can anyone tell me why 1/2 turn would make such a difference in the
heating?
Thanks, MikeK
