Clifton,
The problem with using a gutted 9v motor is the friction. The motor has a lot of
side sprung friction for the electrical brush power pickups.
I've been successful making power pickups using the ealy style 9v wheelsets.

These worked OK for lights, but has some flickering.
If you cut the axels and respliced with plastic to insulate, and small brass
springs to each side, and 3 or 4 sets, I think you could reliably power a motor.
