DC motors: "altered brush timings"

In this thread, under Chris' noise question, Cliff suggested that motors sometimes are optimized to run in one direction. To the detriment of the motor's performance when running in the opposite direction. Ken observed the same thing in car-window-wiper-motors. Now I want to know more about this.

Have a look at the motor I use for my Theo Jansen Leg experiments.
