good evening, and please let me know if i should post this to a different more appropriate group.
i'm looking for help with electric motors.
the goal is to raise a pole very very slowly, about 2-3' and then lower it back down again and then back up again. every cycle should be something like 1-2 hours.
i was thinking i can hang the pole from a rope, run the rope to a pully on the ceiling and then over to another pully on the wall and down, where it'll be attached to one end of a big gear. a motor can slowly turn the gear and as the gear moves around it'll pull the pole up and down.
the problem with this design is of coure the big gear.
can you help me with a better design? perhaps, are there any electric motors which run very slowly one way for a set amount of time or distance and then automatically switch back the other way and then back and forth? if such a motor exists it could be used to simply wind the rope.
thanks for any help you can offer. max
