DC motor - Wikipedia

Speed of a dc motor is directly proportional to the back emf E b and E b = V - I a R a That means when supply voltage V and the armature resistance R a are kept constant then the speed is directly proportional to armature current I a Thus if we add resistance in series with the armature I a decreases and hence the speed also decreases Greater the resistance in series with the armature
