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.

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

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…
