Yeah, I was going to joke that you make it infinitely long. Power/torque is proportional to L*D^2 so the longer you make it, the more you'll get out of it. Practically speaking, you don't want your length to be more than about 2-4X your rotor OD for manufacturability.

Here are two good books for learning about motor design, neither will really tell you how to actually select the geometry of the laminations or the winding configuration. Speed is a good piece of software for analyzing that. Maxwell is also good, but that is going to be out of the price range for individuals.
