Hey guys, new to the site and electronics in General so I wanted to ask this question in a place I know I will get a correct answer, and if not, then directions to an answer or alternative. Essentially I am making a project in which I need a motor to pull something that is under tension, at the apex of the pull I need the motor to stop pulling and I suppose, to release the load its pulling so that the tension it was working against can pull it in the opposite direction. God I hope that made sense. It's like a slingshot or a bow in which your hand is the motor pulling against the tension. My question is, is there a motor that would allow free movement in the opposite direction after pulling without providing resistance? Any help in the right direction would be appreciated. Thanks guys.
