Transfer Function & Block Diagram of Armature Controlled D.C motor 

14.35 it will be G/(1+GH)
A motor is an actuator, converting electrical energy in to rotational mechanical energy. Motor requiring DC supply for operation is termed as DC motor. DC motors are widely used in control applications like robotics, tape drives, machines and many more. Separately excited DC motors are suitable for control applications because of separate field and armature circuit. Two ways to control DC separately excited motors are:
1. Armature Control.
2. Field Control.
