Project design/motor sizing help needed
(OP)
Hi, I'm new here, but I really need some help on something I am working on. I did a search but couldn't find exactly what I was looking for so I thought I would ask for help:
I am doing a simple design where I use a motor, coupled to a set of gears (probably spur gears), which rotates another shaft, which raises and lowers an amp in the trunk of a car (maybe by means of a screw jack, not quite sure yet). What my question is this: I'm thinking that I have to size the motor first before I can design everything else, but how do I do that? I need the motor to run off 12V DC because I want to run it off the car battery (if possible). I hate asking because I don't want the work done for me, but I needed someone to explain it on kind of a step by step basis (what measurements I need to take, what formulas to use, etc) because I don't have a formal engineering background. Thanks a lot if you can provide any help.
I'll probably cross post this in another forum since I don't know how much people view different forums.

Key question: how rapidly? This governs starting torque.
If high speed is not an issue, how about using a window motor or seat lift mechanism?

RE: Project design/motor sizing help needed
You'll have to do your homework like Griff said, define your parameters: speeds, masses, etc. It may be an iterative task because sometimes torques are dependent upon pulley sizes which are dependent upon torques which are dependent upon pulley sizes which are....
