Does anyone know what kinda motors that most drills use? I was thinking it
was a torque motor but not sure.

Also, for DC motors can I get away with changing the voltage to a lower
setting to increase the torque or do I run a huge risk of burning up the
motor?(i.e., are they usually designed for a very narrow operating voltage).
I have this old broken 18v drill and I want to turn it into opening a gate.
I figure that it has enough torque to do it and I can control the speed
quite easily.

If you already have speed control, don't mess with the voltage. What's
broken about the 18V drill? Right after saying it's broken, you say it has
torque and speed control.

Run it at 18 V and either figure out a trigger setting, or hack the
controller to do with what you want.

Good Luck!
