Can someone give me an in-depth guide to the surface "Motor"?

I intend on recreating an Armored Patrol type thing, but I need to know how motors work and how to script them to work the way I want them to work. Help?

This will help: http://wiki.roblox.com/index.php?title=RBX.lua.Motor_(Object)

Motors are used for making movable joints between two Parts. They are used to make a character's limbs move too, meaning that animations use Motors.

NOTE: This is not a request site, you must give us a script or a code to fix.
