Mono and bifilar transformer winding machine :

This is the version I buid for transformer winding. Particularly, vacuum tube amplifier output transformer. Software and firmware made and modified by ghemml.

ABS printing parts and 10mm rods frame for easy DIY and low cost. All 3D parts are design with Freecad.

I use conventional stepper motors but closed loop are better.

I made it for bifilar as I often need it.

General dimensions without control box (approximately) : 52cm (width), 55cm (length), 40cm (height with reel support)

All STL file and updated PDF on FB group : https://www.facebook.com/groups/804317050166139/?ref=share

The wire have a strange color because I use old wire from burnt transformer for testing...

@pierrotlalune, Beautiful work 👍

Thank you for the impressive work & sharing. Of all your videos I have not seen any build demonstrating winding of thick 1.2 mm or more in multiple layers, like 11 or more. I intend to build one such machine but would like to know whether your software is capable of laying out all neatly wound upto 11 or more layers? Also are acceleration & deceleration parameters controllable?

Hi Ghemml, do the actual aluminum/stainless steel parts that make up the machine have to be made or is it a kit that can be bought? I'm very interested in making one of these as I've been building subwoofers for years and with the price of voice coils going up over time, this might actually save me a buck. Thank you for posting this
