Step 7: Simscape/simpower systems/Electrical Sources/ DC

Voltage Source

Step 8: Simscape/simpower systems/Machines/ DC Machine


Drives I


Step 9: Arrange the Components as Shown and connect them

Step 10: Double Click on DC machine to adjust Parameters, and

right click and help to understand the model more.


Drives I


Step 11: Click on icon Shown and change solver to ode23t, and

also adjust the voltage as required from the model in step10.


Drives I


Step 12: Run Simulation and Open Scope

Step 13: Using the same components connect them to work as

shunt and series motors as shown in figures.


Drives I


Step 14: Take Care to change parameters of DC Motors as

shown in figure in order to operate as a Series DC motor hint

Field Resistance must be reduced and also inductance


Drives I


Step 15: For the Three models now at hand,

1- Change the field and or armature voltage, add resistance to the

field and armature circuit simulate, take result, change the values of

the voltage & resistance, observe and take notes.

Hint: take care to change one variable at a time, in order to have

reasonable observations.

2. Find/draw the relation between,

- Armature current and speed,

- Field current and speed,

- Resistance value and speed,

- Voltage value and speed,

- Speed and torque,

- and also calculate the efficiency in each method of control and

find the speed regulation.

3. Comment on the results and the relations obtained before.

4- All this results and relations are to submitted as a report soft

copy or hard copy as you like, and attached - by email - with your

matlab Simulink simulation files as well. Don’t forget to mention

your name and registration number.

Good Luck…
