Help winding my own inductor?

That isn't the proper term for that either.

The term "helical wound" seems to pop to the surface of my ravaged
mind.

Apparently a great deal of what pops up to the surface of that cesspool
you call a mind is what one would expect to see floating around on its
surface...

"Wave winding" may very well be the proper right-pondian term for what
it's called over here: "universal" winding, sometimes called "pie
winding" if the diameter of the winding is large compared to its length.
Sometimes there are several pie sections wound on the same former, and
these are also commonly referred to as pie wound chokes.

I read in sci.electronics.design that John Popelish <[email protected]>
Does this answer contradict your last one?

I said, "How about if you adjust the gap to hold a constant flux for a
given
current as you change the number of turns?"

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

Yes. I misread your question to mean keeping N[phi] constant.

Thanks for the help. It makes a lot more sense, now.

Guys, guys, guys!

If you feed the trolls, they come back for more.

Let's stop playing "I'm righer". It's obvious who's got the wisdom that comes
from years of experience. You've made your statements. Let the jury of your
peers (and we beginners, too) retire in peace to ponder the evidence.

Peace,

and before
you got called on it you thought that any number of paralled conductors
was referred to as Litz wire, as evidenced from your misuse of the term.


Not true. They must be isolated from each other electrically,
except at the terminations. I said that. I know WAY more about it
than you do.

LOL! If, when you go to work tomorrow, you hear snickers and giggles
behind your back everywhere you go it'll probably be because your
coworkers read what you've been posting on this thread and won't be able
to help themselves.


Try it... How many #22Ga wire strands does it take to make one 19Ga
wire?

You lose.

Well, let's see...

One strand of #22 has a cross sectional area of 0.0005046 square inches,
and one strand of #19 has a cross sectional area of 0.001012 square
inches, so 0.001012/0.0005046 = 2.005549 strands ~ 2 strands.

With that in mind, let's take a look at an excerpt of an earlier post of
yours where you claimed that seven strands of #22 is the equivalent of
one strand of #16:

QUOTE

I used 7 #22Ga for just over 16 gauge equivalent. It was about an
inch and a quarter core, and it was like 12 turns.

END QUOTE

Now, taking a look at a wire chart we find that a single strand of #16
has a cross sectional area of 0.002028, so if we divide that by the
cross sectional area of a single strand of #22, we get
0.002028/0.0005046 = 4.019, ~ 4 strands. Not seven, ya fuckin' maroon.

Now, just for grins, if we take your seven strands of #22 and multiply
the cross sectional area of one of them by seven, we'll get
0.0005046 * 7 = 0.003532 square inches. Then, if we search the wire
chart for the wire size with a cross sectional area which most closely
approximates 0.003532 square inches we find that #14, with a cross
sectional area of 0.003225 square inches fills the bill, As I posted
earlier.

Since your seven strands certainly weren't litz wire, that could also
help to explain why the choke you wound with the seven strands of #22
worked when the one you wound with the single strand of #16 didn't.
Simply put, the seven strands represent about a 59% increase in cross
sectional area over that enclosed by a single strand of #16!
You lose.

Convince me some more.

Hmmm. For DC or AC use? If AC, at what frequency? Like beauty,
electricity is sometimes only skin deep.

Mag Inc uses the curves I developed back in 1960 to determine the energy
storage which they post for each of their moly permaloy cores.
If they have DC in them, that must be taken into account.

Hey, you have a nice day too.

Yikes.

Hey, asshole, if you'd taken a few minutes to check the thread you'd
have found out exactly what was going on and you would have gotten the
answers to one of your questions. But no, you'd rather be an
inconsiderate little prick and have everybody else do your legwork for
you.

**** you _and_ your sarcastic "have a nice day" shit.

Except that your lame, retarded ass is only looking at even gauges.

Ther are odd gauges, and half gauges, you stupid ****. 14 is NOT
the nearest gauge.

Since you knew that litz wire was named after Herr Litz, I guess you're
right.

You're an idiot. Bare wires would form a single conductor.
Isolated wires form litz configurations. No braiding or weaving is
required.

Which is what you thought you were dealing with. (A #16 equivalent, that
is...)

You are incorrect.

The coil was initially wound with 14 Ga solid wire.

The litz wound coils work better.

The reason is skin effect. Period.

This is the same retard that re-iterates what is written on a site
to someone to the tune of 40 or more lines, but doesn't have a single
line expressing so much as the time of day here.

What an ignorant, retarded troll **** you are.

**** you, and your petty kaka ass, ya dumb ****.
