Bifilar wire

[prometei]

I didn't know you could make a machine to do the winding!

Well ye, u need one. I made this one pretty quick, it's a disaster Now I'm brainstorming how to make a new winder that could wind bi and trifilar coils. Maybe you guys can throw some ideas in here, pictures or links.......

single winding..you wind 1 wire! right? no problem
2 wires or more..how will they be winded? must they be twisted as well or just take the wires and wind them?


yes it would be interesting if anyone cold show a plan to build a "winder" that would wind multiple wires

Albert has shown once a good winder in hit bedini in germany thread

Howdy Y'all,

Bifilar wire is not the same thing as twisted pairs.  Twisted pairs suppress the electromagnetic effects of the coil.  This is why twisted pairs are used for long range communications wires like Ethernet cable.  Bifilar wires are laid down side by side down the entire length of the core, and usually in only one layer, like a AM radio coil.  They can be laid down in multiple layers, but this extremely tedious to keep the layers lined up properly.  Bifilar windings are worth exploring, but my work is in another area at this point.

hmm... interesting. So has any1 got a one layer bifilar coil in their radiant charger setup? I've got a 8 cm coil, probably more than 10 layers. I was actually thinking about winding some longer coils so that only maybe 3-4 layers would be necessary, easier to wind and they would turn out neater. But I don't know if such long cores (welding rods) would require stronger magnets.....?
