Modeling of Armature Controlled DC Motor Using MATLAB Project Report

Introduction To Mechanical Mat-lab Project:

           A DC motor is a basically a simple electric motor that uses both electric field as well as magnetic field to produce a torque that can run a motor. This conversion of energy is utilized for the generation of electricity. The project “Modeling of Armature Controlled DC Motor Using MATLAB Project Report” designs a DC motor that is armature controlled. Hence here the armature coil is responsible of the magnitude of the current produced.

         The principle of operation used in this motor is electromagnetism. According to this principle, whenever a conductor that is carrying some current is placed in an external magnetic field a force will be experienced by it. This force generated is proportional to the current flowing in the conductor and also on the strength of the external magnetic field.


            In the project Modeling of Armature Controlled D.C Motor Using MATLAB the armature control method is employed. In this method, the voltage which is applied to the armature circuit of the motor is changed by keeping the voltage supplied to the field circuit of the motor constant.

            Thus, here the motor must be excited by an external source in order to implement the armature voltage control. As the armature voltage is increased, the no-load speed of the DC motor increases. However the slope of the torque-speed characteristics do not change as the flux produced is a constant parameter.


       In this project the speed of the DC motor is controlled by the armature. However there are many other methods that can be used to control the speed of the DC motor. There’s the voltage control method in which changes in voltage are made to control the speed of the motor. In the flux control method, the speed is controlled by making changes in the flux. Another method is rheostatic control in which the rheostat variations control the speed.

  1. i am not able to access this.. it is showing some power gui error.. can some one plz help me out

  2. dude for that power gui error try inserting power gui block from the simulink library just keep the block somewhere near the circuit and run the process
