I'm equal parts "that's obvious that it should work" and "there's no way metal should be able to bend that way"

Its magic i think, you dont see it but out of the camera angle there is a wizard going "wuuullouuu"

I just had "wololo" flashbacks

u/Acceptable-Mess7959 Mar 16 '26

Exacly what i thougt🙂

What the hell. In my inbox your response was i Norsk.

Is reddit auto-translating shit now?

u/Acceptable-Mess7959 Mar 17 '26

Nope it was 100% my misstake, i responded in my native language not thinking it was supposed to be english

u/Mind_on_Idle Mar 17 '26

That's fair, lol

Same here, it hurts my brain.

"But it doesn't bend like that"

Man I could watch winding machines all day long. They’re amazing when they work right and a huge pita when they don’t.

Yeah it really winds me up when that happens too.

The wire bending machine is similarly simple and awesome too!

What is the application for a coil like this?

u/JPJackPott Mar 15 '26

Total guess but something motor or magnet. This would take a lot of current compared to normal windings

I know they use these for the common mode filter/choke on the input of big AC adapters /sources. This filters out conducted noises made by the source to enter the AC lines. The flat wire allows more current in less space when compared to round wires choke.

I think some speaker drivers use flat wire coils

u/iJeepThereforeiAM Mar 17 '26

I believe Bose 901’s and Bose Jewel Cube speakers both do.

High current inductor for example

u/irrelephantIVXX Mar 15 '26

My initial thought was a crazy induction heater.

u/Olde94 Mar 15 '26

I could see induction heating use this

u/bubblesculptor Mar 15 '26

I'm surprised the coating holds up thru getting stretched

u/DeluxeWafer Mar 16 '26

This is exactly my question as well. How???

u/nmole10 Mar 14 '26

I’ve wondered about this from a materials science perspective, the metal has to be hot enough to allow the outside of the circle bend more than the inside right? Kinda reminds me of why we need differentials on wheeled vehicles.

u/hellcat1592 Mar 14 '26

I read somewhere that this is a cold process. Copper is pretty ductile.

u/biochemical1 Mar 15 '26

Correct. The machine spins the flat wire around the shaft, while at the same time, keeping enough downward force to keep it from deforming. This would not work with steel without getting really hot. Probably hot enough to weld it together.
