Effects of gaps in inductors and transformers

[MassiveProng]

Your "attempt" at humor expressed as derisive insult is _NOT_ funny.

Your opinion is your opinion, retard. You are beyond help.

 

[MassiveProng]

And you could not solve that with judicious use of inductance and
capcitance?

Idiots that do not make power supplies always think the world can be
stuffed into a predefined chassis size.

Get a clue, dipshit. They are called design constraints. Of course
the supply had filtration in it. It is the best we could pack in that
size package, and we beat the shit out of the competing product's
specs.

Again, you know nothing about which you spew.

 

[MassiveProng]

So you ended up with a sucessful design. That is good.

No shit.

 

[MassiveProng]

No. Not at all.

You missed the point completely.

Standard connectors are standard for a reason,

STANDARD SIGNALS, dumbass. Line level audio. Guess what S-VHS has
in its spec? Line level audio, you idiot.

they
reliably intermate and match standard connectors.

No shit.

Using a connector alien
to the purpose is counterproductive.

S-VHS is for passing audio/video signals. That means that a person
could use it in a design for passing only video, or only audio, or
both, and it is perfectly normal, dipshit.

If you produced wall warts that used
N connectors for the output you would fail commercially.

If you had any brains, you'd know that the connector chosen was fine
for the job, and is in fact used by Sound Blaster, VCR, DVD
manufacturers all over the world.

You lose... again.

Small, impractical nit: Won't the flux continue to increase with
current, at a declining effective permeability, approaching u=1 at
full saturation of the iron? Admittedly, this is a pretty low slope,
but I don't think it goes to zero.


I know a guy who has a secret process for treating metglas, up to a
permeability of about 1e6.

Who's that?

Well, I meant, is he, his company,... selling this. Is there a website?

but if you ggogle his name, you'll get all sorts of interesting stuff.
He's a very cool guy, and does some outrageous magnetics. He sponsors
the "Farady Cup" awards, which is a pretty good English pun for a
French-sponsored award.

There are roads near my work...

Van Allen Way...

Faraday Blvd.

The California coast is cool!

Prevention of saturation is the main reason, even if there is no DC
component involved.

Which statement relates directly to part 2 of my question: given
constant ac excitation of a winding on a ferrous core, what happens to
flux density when a gap is introduced?

John

 

[John Larkin]

If I may ask, does "constant AC excitation" refer to voltage
or current?

Voltage. But let's let Missing Prong answer this one. since it's
related to his post.

**** you. Since it is voltage that causes saturation, you have laid
out an invalid test. So **** off, jack-off.

I understand. Just cutting off an escape route.

based on his response, I have to wonder how much of *his* work went into
designing the products to which he refers (and which dont look that hard
either). the phrse "midgets standing on the shoulders of giants" might
be applicable.

Cheers

Interesting stuff. Thanks.
And we are less than 1 and 1/2 hour drive away.

Invalid? The physical situation is real, and the answer is fairly
simple.

Why do you pretend to know stuff that you clearly don't? And call the
people who *do* know stuff "retards" and worse?

It's easy to look like a moron here: pretend to know things, say
things that aren't true, be obnoxious about it, and stonewall when
challenged. That behavior has a bonus effect of convincing everbody
you're a creep and making everybody dislike you. Is that what you
want? Are you a pain slut, seeking public humiliation? That's what
you're getting.

Or, you can comment correctly on stuff that you *do* understand,
research the things you don't (and learn) and admit when you don't
know things, and when you're wrong.

Prongs don't matter here: balls do.
