Abstract: Motion control plays a very important role in traction purposes. Different type of motors AC & DC are used depending upon the type of traction. DC motors are used in many industrial and commercial applications require higher performance, reliability, variable speed and so on due to ease of controllability. DC motor are widely used because of easier controlling, whose speed is directly proportional to the supply voltage. Using this relationship between the speed and the supply voltage, in this paper mainly focused on the simulation of a pulse width controlled direct current motor using Simulink environment in MATLAB for Electric Locomotive Control.
