Question

Copper is just the windings, no? Usually enamel copper wire

it seems, but not always covered in resin.. not sure if that's good for longevity, an 800W single phase AC motor from a vacuum cleaner I disassembled this morning doesn't have them either - which actually is the reason why I need a step-down transformer, preferably some makeshift autotransformer from a 24V step-down transfo where you just tie the primary and secondary together, but I can't seem to find them in anything but 12V variants, and that wouldn't be sufficient I think. On 230VAC it got quite hot after a while, even with its cooling blades inside the unit. Without them.. eh, I doubt that it'll be happy with anything but something around 200. But high power transformers are pretty expensive even when it's just a 24V one which can drive a couple of amps.. hence why I started looking at the modularity of a transformer which I can rewind the secondary to meet the demands any project at hand that's within its power rating.
