I am trying to make a drum winch for an art piece that slowly lifts and raises a curtain - I have attached a simple image.
The movement of the curtain will be defined using Ultrasonic sensors to detect when the curtain is nearing the top or bottom of its range. The curtain should be moving all the time, but slowly.
The drum winch will form the base of a rotating structure that weighs approximately 3kg. The weight of the curtain is a maximum of 1.5kg.
The distance will be defined by the sensors so the motor doesn't need to be that accurate but it does need to be as quiet as possible (some sound is fine). The servo motors I have tried have been quite loud. I was thinking a geared DC motor might be better?
I'm fairly new to using motors and unsure of the best type to use.
Also would I need to incorporate an automatic break?
Any help would be greatly appreciated. Thank you in advance!
nb: I have seen a similar question here (), although I think my requirements might be different since the motor itself doesn't need to be particularly accurate, just slow and quiet.
