I am wondering if there are any worthwhile bits in this type of machine that can be used to make homebrew sensors for the RCX? If anyone has ideas or experience (...)

(...) Um, the back-EMF of the motore isn't related to the motor load per se but rather the relaxation of the current in the coil when it moves off the stators.
