I am confused on where this topic should go so I am posting in this section. What are some strong motors whether they are stepper, servos or dc that can move roughly 50-75 pounds along and parallel to the shaft which the motor is driving? Where would be a good place to purchase them and their drivers? The idea is to have a bunch of drinks stacked up on each other approximately 2-3 of these (see picture below) on top of each other all on the same shaft. The power source will need to be plugged into a typical 120V outlet you find in a home or store. (The max current would typically be 15A from these outlets so that's what we're looking at)
We want to have the motor drive this shaft alone to test its limits but what ultimately we will do in the end is have gears with different gear ratios to lessen the torque.
