Ahhhhhh....ok.....well I could put maybe 150 ft-lbs of torque on a tension wrench....that'll beat your electric motor any day and I'd be stalled too

Or how about a steam engine but hook it up to a high pressure gas bottle? That'll beat your electric motor too if it doesn't explode

But if torque without rotation is all you want then why not just hang a lever off whatever contraption you're thinking of making and let gravity do the work? Last I heard, you don't even have to plug the Earth back in to recharge it .
