What's that Lassie? You say that Lloyd E. Sponenburgh fell down the

Ideally, aren't there constant-torque AC motors that can be stalled
indefinitely?

yep... So called "impedance protected" motors. I've been looking for one
that would produce about 20ft-lb torque at around 5 rpm.


Could you find one that would produce 10ft-lb at 10 rpm, and gear it
down

Or one at 5ft.-lb at 20rpm?
Or one at 2.5ft-lb at 40rpm?
Etc.
