The figure below on the left shows an armature controlled de servomotor driving a load through a gear train, which is commonly used in a closed-loop control system. The schematic diagram below on the right represents the armature circuit rotating simply due to the voltage ea(t) applied and the fixed magnetic field B by a permanent magnet. The armature voltage as an electrical parameter ea(t) is considered to be the input to the system. The resistance and inductance of the armature circuit are Ra and La, tespectively. v»(t) is the back emf and directly proportional to the rotational speed of the armature as v,(t) = KpWm(t), where Kp is a constant of proportionality called the back emf constant.
