NXT Motor Hardware & Software

Two postings bring a lot of information about the NXT Motor.

Philippe Hurbain (aka Philo) brings measurements and insights into the performance of the NXT motors, when used in the NXT set with both regular batteries and ordinary rechargeble batteries. The Lego Mindstorms firmware and mechanics is done really well, and the motors perform much more predictable than its RCX predecessors. The NXT can even correct for the loss of power that results from using the 7.2V of rechargeable batteries (as opposed to the 9V from regular batteries). There are also photo's on the internals of a real NXT motor. (One piece of advice to take away: never connect an NXT motor to an RCX brick).

Jim Kelly at The NXT Step complements nicely with a discussion on how to control an NXT motor using the Lego Mindstorms NXT software.
