DIY Toroidal Winding Machine

audioPT · 23rd March 2004, 06:47 PM

Hi!

I've searched all the foruns also as google and can't find any design of a Toroidal Winding Machine.

Any help will be welcome.

anyone?

I doubt that such machine exists except for professional ones.

Thanks 'bout the link.

It's sort of that.

I'm winding using a fishing artifact, i don't know the word in engkish...

I've seen in a magazine a design of sucha a machine, but I can't find that.

I know that it's difficult, but I work well in mechanics

Any more info?

Regards

I remember an article in Elektor magazine rather a long time ago (late 80s, early 90s) on that topic. Not exactly DIY, but a brief description how toroids are made.

Bingo!

That's that magazine...

Any copy of the article out there??

The only type of toroid winding machine I can think of that would be relatively easy for a DIY type to build would be a hook winder. The concept is simple - you have a compressed air driven actuator with a fairly long stroke, with a chuck on the business end. Into the chuck you insert a polished metal hook that looks rather like a knitting needle with a somewhat larger hook on the end. The hook passes through a hole in a small table, which is where you place the toroid to be wound. You start by threading the wire through the toroid so that the hook can engage it. Trigger the actuator, and the hook grabs the wire, pulls it down through the hole in the toroid, and shapes it around the toroid. You pull the rest of the wire through the toroid, bring it back around, and do it again. It sounds awkward, but once you get the hang of it, you can whip through turns pretty quickly. This type of machine is the industry standard for toroids with a relatively small number of turns using a relatively large wire gage. If you want to put 10,000 turns of #44 wire on a toroid, you'll be using a conventional (read complicated and expensive) toroid winder rather than a hook winder.
I've used hook winders to assist in winding a large toroidal 60Hz transformer by hand. I have also wound some toroids completely by hand using a crude shuttle made of printed circuit board material or a 2' long piece of 1" PVC pipe. I wind the wire supply on the shuttle or pipe, and thread it through the toroid for each turn. It's very tedious, but it works.

7500 USD used! And only for small toroids. I wonder how much a big machine will cost?

Tanks wrenchone

I get the idea.

Check my design to see if I'm thinking right
