We are working on interfacing the LEGO sensors and motors to a compact lightweight computer for more sophisticated control. Aret Carlsen brings us a video demonstrating how one can hack into the NXT Standard Motor:
See also quadrature encoder or rotary encoder at wikipedia and the LEGO NXT Hardware Developers Kit (LEGO NXT data sheets). Philo also has the pinout diagram on his page on deriving power from the Motor A port.
Additional details can be found in the excellent book Extreme NXT: Extending the LEGO MINDSTORMS NXT to the Next Level (Technology in Action) by Michael Gasperi, Philippe E. Hurbain, and Isabelle L. Hurbain.

I am very impressed with your project. Recently, I have started playing with the nxt motor and I also want to learn to control the nxt motor. Can you please let me know the details of controlling the nxt motor, that is, what does each of the six wires in the cable mean and what kind of signal they carry.
I will really appreciate your help.
My apologies for the delay in my reply.
Yesterday I posted a piece on the motor wiring:
I hope that this helps you out a bit.
Do you know where can I find more parameters about the motor, like its: terminal resistance, output torque, torque constant, back electromotive force constant…etc ? Please let me know.
The only place I know where you can get this information is on Philo’s website where he has collected a great deal of information about the NXT motors:
I hope that this helps.
There was another link in the above website that was pretty helpful. It had link had some of the motors parameters. http://web.mac.com/ryo_watanabe/iWeb/Ryo%27s%20Holiday/NXT%20Motor.html
Sorry about the typo.
This is a nice find!
