Damn that’s how they get it so good. Tried to wind my own, I don’t care what videos are out there, diy coils suck


dejvidBejlej

After being into diy for long enough you realise the best way to do anything yourself is by building a factory full of tools. Wait that's not diy


intashu

Well, true DiY is you built your own tool. But it has a lot more cut up street signs screws and wood involved... And it *mostly*works most of the time!


YellowOnGrey

The best approach is to start with something as close to the final desired product as possible. Only wind a coil yourself if you absolutely have to.. or if you're a bored masochist

>Wait that's not diy It would be if you built the factory yourself.


ran0427

No I definitely needed the CNC mill. That way when we need to replace a door I can make the bolts for the surface mill so I can finish the plattern on my grinder so I can sharpen the blades for the table saw to cut the door to size. Simple.


TheRealMicrowaveSafe

Someone had to DIY it the first time. Close enough for me, I ain't lookin' to reinvent the wheel.


dejvidBejlej

That's my point 🤷‍♂️ Eventually you'll just buy the thing you need because it's better quality and takes way less time. Only custom parts and builds are worth any effort if you're not doing it for pure enjoyment.


Cingetorix

it is if you build the factory yourself


ValuableNatural172

One time I unwound the wire from a fan just for fun and there’s like a full blown 5 miles of wire in each one


keepthepace

There are DIY coil winding machines. Check out OpenActuators. Though for now they only do solenoid coils (and are much slower)


isMattis

Will do, thanks for the direction!


Cariboob

Had to do one in grad school. never again.


EpicWildlifeWarriors

When I bought a lathe it came with a coil winding attachment...

I enjoyed that

I miss the sound of factories. I worked in a few fabrication plants but since then have barely set foot in one, and this video brought the sounds all back to me. time for some factory visits!


steelreal

Yeah man, I sure miss coming back to my folding table the next day and cleaning off a thick layer of black soot. I miss taking a deep breath of fresh air thick with oil mist.


GapAnxious

I worked in metal fabrication so it was all fine! Apart from the acid baths and the shotblasting dust- we made metal lamp posts. er.. and welding chemicals and the NOISE, and the diesel fumes from the "shifters" and tractors and fork lifts. ..and the aluminum particles.


eggplantisgross

Do factories just let you come and visit?


John5247

Having personally wound a few wonky windings in my time, that was a very satisfying watch.


flume

"wound a wonky winding" sounds like a great children's book for parents who are engineers


John5247

Yes indeed. A very wonkily winding around a rusty nail was my introduction to electromagnetism by my dad.


sgtsteelhooves

Here's a more manual way to do it. (for stators though) https://imgur.com/a/4gK42sA


UserMull69

Wouldn't that burn the shit out of your fingers though?


sgtsteelhooves

Ehh not too bad actually. If you hold on real tight it will start to tho. It's pretty smooth and you can go slowly if you want.


billyboblee

[This YouTuber does it by hand crank device. Around 20s mark](https://youtu.be/6MYRbwrIkPQ)


sgtsteelhooves

Wow that was actually super professional looking with basic tools except I didn't see how she connected the wires inside.


GoreSeeker

I just imagine them in R&D wondering how fast they can make it, and realizing it can go this fast.


brimston3-

You just know they tested it *faster* than this, but then had to back it off to make sure the wire wasn't damaged as it blew through the feed system. All the while laughing maniacally.

now that is sexy.


CzarDestructo

If I recall this is from an Audi electric vehicle production facility video.


Lt_Schneider

seems a bit small for an electric motor for a car is it for the steering or something else?


UserMull69

I'd deglove my entire hand if I tried that.


Idunnosquat

While it is cool and all, I don’t really know what is doing.


Thassodar

This is how they make most alternators in cars, from what I understand. I believe computer power supplies also have a decent amount of wrapped wire as well.


Idunnosquat

I understand that part but the winding is so fast, I can't see the path.


BuccellatiExplainsIt

It's way too far to see anything


Idunnosquat

Fast?


Gocho2

Very slick!

I remember in the 90’s. Whenever you would see winded coils, they were always super neat, unlike this. I remember trying to unravel a small one, 5cm or so, from some circuit board, located within a blue plastic bottom and clear plastic housing and realizing just how much winding was in there, with an extremely thin cobbler line.

Mesoposty

There was a video like two weeks ago of someone doing it by hand


CreatorOfIdeas

I need a slowmo for this. Dahm that's fast


InitechSecurity

That was awesome. Why was the first set of windings done slower than the rest?


Cariboob

I had to do this by hand once in grad school


CrazedKenyan

The sweet sound of high numbered RPM


honsten

Do they balance the armatures after this step? You can see the balancing marks on the final part.


stb2021

Why does the first winding stage sound slower than the others? More force to tightly wind around the armature’s(?) sharp edges?


m3m4t

I don’t know this specific rotor, but we have a winding machine for Brushed DC motors (therefore, with commutator) and the first winding is done slower for many reasons: - it’s the first point of connection of the wire to the commutator, doing it faster is possible, but you may bend the hook because all the force goes there (you don’t have other windings to pull from) - going slower gives you better control on the winding force and due to the fact that you have a “weak” starting point for the wire (the first hook) it’s better to go slower to have a smoother winding This specific rotor may have some problems like ours (as all of them have it, if you’re going very fast) and I could sum it up by saying that the first winding has to create the wire “lock” on which the other can pull without having the wire slipping.


anged16

Hehe machine go WIRRRRRRR


ashpravp

As per operation shown, coils should have wound 180 deg. Final product shown has coil wounded at 45 degree. How.


ashpravp

Need to see in slow motion to understand movement.
