Coil winding.  Looks intricate.  It can be automated though.
Here's how it's done in an industrial setting:

Couldn't find any videos of winding machines making axial-flux stators. 
Here's one of an axial flux stator core being laminated, though:

Because this is a Youtube short, I'm not sure how long it will exist before disappearing into a broken link.
Not as bad as Instagram, but...

Almost all of those methods look a bit hard on enamel to me.  Some of them are way more messy than i would expect of automatic coil winding.  Some are ultra precise and smooth too though. 

Setting up the cnc tool paths and everything must be quite a chore.  I've never wound a coil, nor programmed cnc, so I really don't know what I'm looking at, but it looks pretty involved.   

I tend to watch the videos out of pakistan with a guy in sandals winding motors, rebuilding motors, etc.  Their shops and tools tend to look more like my shop.  Their worksmanship is usually top notch, and their methods are within reach of your average guy. 

Thanks for sharing these videos.  You never know what you watch that will inspire some scheme down the road.

Those are pretty cool to watch!!
