The ol' lady is watching something stupid, so it got me thinking about hand-wound motors. Has anyone ever made one? Is it possible these days? I have not googled this for the sake of conversation. I'd love to make one with a custom label.

Dymond used to make a blank armature motor kit.
.

I feel like I want to wind a 17x2 for my Thunder Shot with a custom label called Thunder Down Under. Design to be presented at a later date.

I am watching. Let's see this.

I'm not sure how a person would pick the wire size. There is epoxy covered wire available.

Google really has killed conversation hasn't it... Who knew How I Met Your Mother would be so prophetic:



Probably the best scene from the entire series.... but, back on topic... could use the wire sizes from Kyosho's Lemans motors as a guide...

I came across some magnet wire at a surplus store. For fun I rewound an old stock motor blank. IT's not incredibly hard to make one that will spin up, the problem is making it perform. Mine spun on a turbo 30, but that's all I did with it.

I've rewound tiny micro helicopter brushless motors but that's kind of easier as the armature is static in BL motors , the only time a rewound a 540 it ran for about 30 seconds then the wire shifted and it ate itself in an instant , my lesson was that you have to be tight and neat with the wind , maybe even coat it with lacquer after ?

I used to rewind motors. I had a few spools of some various magnet wires. Just looked at specs of different motors for how many winds and the wire gauge so I figured about how many turns a specific wire gauge would fit. But the biggest issue is I never knew what kind of solder/braze to use on the comm strap, so I used silver solder that had a higher melting point. It would work until it go so hot the solder would melt and the motor would stop. Resolder and go again. Some were good, some sucked. Just running around on my long driveway, small dirt track, or my cousins cul-de-sac.

I don't see this turning out well since They took your thumbs.

So what was the deal (the big upgrade in price) with handwound motors? Seems like an area that a machine would do better and more consistently.
What is the hand/fingers doing to the wire or the wrapping that was so superior in performance?

Machine wound was sloppier and looser winding than an experienced human.

There is a great scene when they are walking through the AE factory in one of the Gene Hustings videos where you see a tech winding an armature extraordinarily quickly. Truly impressive.
