I'm considering building a mount for cameras or telescopes which I would want to move at the rate the Earth spins (i.e., 1/1440 rpm). I've considered using the mechanism for a clock and just using the hour-hand with a 1:2 gear, but from what I've seen, inexpensive clock movements are not made to support any real torque for moving an object with significant inertia.
More generally, what's the best/most economic motor approach to drive a system with significant inertia at very low rpm? Speed needs to be consistent and considerably smooth
Are there any good, economical solutions to this? Ideally I would like to power this with a low-voltage battery pack, so I figure a synchronous motor wouldn't be useful (plus I don't know if they can operate at slow enough speeds).
p.s., this is my first post, so I apologize if there's a better community that I should be posting to.
