Preparing to wind a motor coil or more. Need some info to consider a
shortcut. Putting aside the issue of current handling capacity, does
anyone have awareness of whether a multstrand wire made of smaller
magnet wires can serve instead of a single wire with the same number
It would mean handling a less fragile wire set, and keep from having
to set up a coil winding jig.

3- ten turn coils in parallel is not the same as 1- thirty turn coil.
If that is your question.
But if your just trying to substitute stranded wire for solid wire of the
same gage, then thirty turns is thirty turns.
I think you have an insulation problem though.

Shouldn’t be a problem its called multifilar , What voltages are

1,600 volts, low current.

Enamel and formvar should be fine for 1500v. It s 105c rated. Depending
upon the number of layers (volts perlayer) you should be fine. Just don’t
use random winding ( it takes up more space ). Multifilar may make
layered winding more of a challenge.
As for a winding Jig, build one. You'll be glad you did. I did a 6
phase motor on a hand built jig, and it made the job so much easier.
Rosenburg's book is good reading on the subject of AC motors if that’s
what your doing, but lacks the design side of things.
