Buy a light dimmer for $4 ... hook the dimmer to the step down transformer
then hook your voltmeter to the motor while turning the dimmer up.
It's an old variable Power Supply trick ... .
It works at from 40 to100% of output so 24 to 12 vdc is 50% ..well within
the range.

Sounds like an interesting dodge, have to remember that one...

But if you want the light dimmer to have a long and healthy life in
that duty, make sure it's one rated for low voltage lighting like the
Lutron Skylark SLV-600P. (Of course, some people have access to a
deeper junk pile of "Good Used" light dimmers than others... ;-)

The LV rated ones have the extra circuitry inside to handle
transformer inductive and/or switching power supply loads common to
low-voltage lighting without a "Magic Smoke" incident. Regular
dimmers want to see a straight resistive Tungsten load only.
