Motors not working

I am trying to make a Ferris wheel for my game, something simple. Yet I can’t get the motors to work! I turned them around, made sure everything was unanchored that was supposed to be. And then… I got it! Or not, because after a few seconds the wheel stopped and the hinge was sitting lower than when it started. Could someone help me fix it?
