Help winding my own inductor?

[DarkMatter]

You are hopelessly lost and when you refuse to even consider that
offers to help you out of the woods are being made by others more
knowledgeable than you are for no other purpose than to help you out,
you really put yourself in a position which becomes more and more
difficult to extract yourself from. Pity...

Your first mistake was assuming that I am not knowledgeable.

Then you claim to have "helped out", when you did no such thing.

Your lame ass even stated many things that I did not say, and
claimed to have said many things that YOU did not say.

You are a piece of shit, and that will not change, no matter how
hard you try.

You keep stalking me, fuckhead, and it WILL reverse on your lame
ass. Consider THAT as your ONLY warning.

Oh my! John, you've been WARNED! Dimbulb does such when he has
lost the argument.

John, keep up the good work! You-da-man!

 

[Keith R. Williams]

DimBulb, perhaps you'd like to read the patents. There is also a
"proximity effect" referred to. I believe someone else brought
this up in this thread.

Funny. They constantly refer to skin effect. Even in the PBS
documentaries describing them.

Now *there* is a definitive source!

I never believed it either, being at a mere 60Hz, but one hears
power boys in this group mentioning that there is an effect... all the
time.

Sure, at huge currents little things matter. I've read articles
about power lines constructed out of a sheath of copper (a.k.a.
pipe) around a helical stainless helix (strength).

I shouldn't have to dig one up.

Understand. Your shovel is dull.

Anyway, I happen to know that there are notable effects at even
10kHz. So there will certainly be effects at 20kHz, which is where my
argument was centered. The circumferential "skin" on the wire is the
main factor here. Litz wire increases that whether there is weaving
or not, Regardless of the woven styles used in HF RF systems, there
are plenty of litz offerings by these wire makers that are NOT woven,
and are not centered on HF RF use.

Perhaps you should *learn* from others here. It might make you a
better engineer.

Anybody in the switch mode PS industry knows this.

Evidently not.

 

[James Meyer]

Those lines are typically NOT copper. They are not saving copper
either.

Fine. Substitute whatever conductor material makes you happy.

My bundling of multiple mag strands to garner gains from skin
effects IS a litz configuration because THAT is what litz
configurations are for, regardless of the fact that the best
configurations for the highest frequencies uses a woven form. That
does NOT state that woven forms are the only that qualify for the
moniker.

From the MWS wire company web site, "The term litz wire is derived from
the German word litzendraht meaning woven wire."

MWS is a very large wire manufacturer and they should know what they're
talking about.

Multiple non-woven conductors are better than single strands.

Multiple strands get around the limitations imposed by the skin effect.

Multiple non-woven strands are *not* litz wire.

READ IT. It says that that is where the term was derived. It does
NOT say that that is the meaning of the term in current use.

MWS is a very large wire manufacturer and they should know what they're
talking about.

MWS is the site where I saw 3 strand litz. It is NOT woven,
dingledorf!

Multiple non-woven conductors are better than single strands.

THAT is what *I* said! It does NOT have to be woven. EXACTLY!

Multiple strands get around the limitations imposed by the skin effect.

No shit.

Multiple non-woven strands are *not* litz wire.

It depends on the wire used.

I read in sci.electronics.design that John Popelish <[email protected]>

Then the inductance is *independent* of the number of turns, by the
definition of inductance (induction per unit current).

How many Gilberts are we talking here...?

hehee...
