Once in a while on the used market you can find a B&D 1405 3/4" drill motor.
Runs at 375 RPM at 10A and is reversible.
I have been using it with a B-B Brothers W200-5 (now Wintech) 30:1 worm-gear
winch for about 35 years.
Thank goodness it has a side handle because when first cranking up the tower
you really need to hang on.
The motor never runs hot. I do take 4 breaks when cranking up the tower just
to make sure guy wires, ropes and everything else is not tangled.
And B&D still services this drill motor.

IIRC, my US Tower TX-472 + Force12 C-4XL goes up/down in a little over 30
seconds, using a Milwaukee Super Hawg (pn
1680-20) that runs at 450rpm. It pulls 13A at full load and should not be
confused with the smaller Hole Hawg. The tower uses Fulton K-2550 winches.
The only issue with taking my tower up/down in 30 seconds is, I have several
feedlines hanging off the tower, along with two wire antennas. I HAVE TO
stop periodically in order to keep things from tangling. So far, it runs
stone cold.
I found the Super Hawg as a factory refurbished unit on eBay for a little
over $200 shipped.

in the worm-gear winches.
There are rating and there are ratings. Most drill motors are rated for
intermittent duty with short run times and long cooling cycles.
I purchased the largest Dewalt that Lowe's carries. Drilling 3/4" holes
in 1/2" thick I-beam, I burned it up in less than 5 minutes and I had just
purchased it.
Drill motors for mixing as have been listed on here may be rated
differently, or with a larger reserve/safety factor than those for
drilling holes. IOW two motors rated at 13A with one for mixing and one
for drilling may not have the same ability to raise a tower.
I've not found a correlation in the ratings. From experience, I've found
a drastic difference in ratings for drill motors rated for long run times
VS the typical short run times for drilling holes.
I'd limit my purchases to a motor rated for long run times such as mixing.
