Hello, I have a geared ac motor; I'm not sure what the correct term would be
but it will only turn one direction regardless of polarity. What I need to
accomplish is to reel in a string of about 20" until a set point where it
would be automatically fed back out. It will be an elevator of sorts to
lift a ball (about 5 lbs) about 20". The end points I know can be
determined through simple limit switches which I know how to setup, again
its the mechanical aspect which has gotten me thinking. I realize a dc
motor would be much more convenient for its reversible nature. It would
have to have a gearing that would be able to pull in this string with a load
of about 5-6 lbs on it, ideally the full 20" could be taken in under 30
seconds. I'm thinking a simple battery powered reversible drill would serve
the purpose well. Does anyone have any thoughts on where to locate one, I
know the prices are quite steep on e-bay with batteries included which I
would not need. Ideally I'd be able to use my current motor. I am willing to
use dc and in reality if a cheep source were to preset itself would be
preferred. Any thoughts are welcome. Thanks in advance....
