The armature resistance of a shunt motor fed from a 220 Volt DC source is 5 ohms and the resistance of the excitation winding is R ohm and it rotates stably. Then, a resistance of R ohm is added to the excitation circuit (a resistor with the same value as the winding resistance) to control the speed.
