Yes, I'm reworking the guts of a treadmill to use the DC-motor
to give good speed control, because I need to avoid random
winding.

Absolutely not.
Multi strand wire does not have any insulation between the strands and you
would only have one turn for one turn.
When winding motors, a sample wire is usually inserted and formed into the
lamination space. The sample turn is taken out and measured onto a winding
form, for size. Wind the winding with as many turns as needed and then tape
the turns together loosely but enough to keep it neat, usually ate the ends
out of the laminations. Insulate the steel with hytex or fishpaper,
insulting materials to protect the wire insulation for the sharp corners and
then thread the winding you have made into the lamination slots. Bend the
ends over to take up the least space and make sure the windings are
protected and taped into place. Dive wooden or synthetic wedges into the
lamination ends to stop vibrations.
When all winding are in place put the whole thing in a oven and heat for a
few hours, dip in insulating varnish or high temp paint and bake some more
to harden and hold everything in place. Clean laminations and wire ends and
connect series and parallel desired windings.
Use high temperature coated wire, formel or hmmm.... forget the other high
temp names of insulation materials for wire enamels.

The OP said "whether a multstrand wire made of smaller

Multistrand wire is composed of non insulated strands.
Is the term "multstrand" not a typo?

"Magnet Wire" implies it is enameled or has some other insulating
coating
I do not think the OP implied non-insulated wire.
