wire for high current inductor

[Budiyanto]

I'm designing a 1 mH inductor with max current of 30 A. Anybody can give m
suggestion what kind of wire should be used? thanks

** Enamel coated copper - maybe the high temp grade.

But that is the very least of your problems.

Do you care about the Q of the coil? And if so at what frequency? Or
is this just DC. (Oh, air coil or will there be magnetic material
involved?)

Firstly, thanks for your suggestions George. I don't have any ideas abou
the Q factor but it would carry dc current with high frequency switching o
10 kHz. For the core I prefer magnetic material in the coil.

About Phllip's comment, I didn't find enameled copper for such high curren
available from Farnel or RS.

** You can ue more than one wire and parallel them.

For what you are now describing, as many as 10 twisted strands might be
advantageous.

BTW:

Look into the use of powdered iron cores.

Big ones.

You could always salvage enamelled wire from a transformer or motor
or...

Hi Budiyanto, I haven't made any suggestions, Just trying to
understand what you want. I like Phil's idea of using several stands
of magnet wire.

I've made a bunch of air core coils but don't know much about magnetic
materials.

At 10kHz a 1mH inductor has an impedance of about 50 ohms... at 30
Amps that's a voltage of 1.5 kV! Is that right? This sounds like
some very serious power engineering. (Which is way out of my
league.)
