For Electrical & Electronics Engineering 3rd Sem scheme and its subjects, do visit Electrical & Electronics Engineering (EE) 3rd Sem 2021 revision scheme. The detailed syllabus of dc machines lab is as follows.
Course Objectives:
- To practice hands-on experience with DC machines and able to test machine performances
- To know the faults of a dc machine at breakdown condition.
- To analyze speed control techniques of dc motors and to develop performance characteristics.
Course Outcomes:
- Identify the construction of DC machines and develop magnetic curves.
- Develop the performance characteristics of various types of DC generators.
- Apply various speed control techniques in dc motors to plot the speed curve and testing of dc machines.
- Develop the performance characteristics of various types of DC motors.
Module 1:
- Dismantle and reassemble a DC machine and identify parts.
- Dismantle and reassemble various types of starters and identify parts.
- Run a separately excited and self-excited DC generator at rated conditions and plot OCC, and identify critical speed and resistance. Deduce the same for different speeds.
Module 2:
- Plot the efficiency curve of self and separately excited dc generators at rated condition
- Develop the internal and external characteristics of dc shunt generator at constant speed
- Plot efficiency curves of dc series generator at different loads.
- Plot the efficiency curves of DC compound generator at different loads in (i) Long shunt configuration (ii) short shunt configuration
Module 3:
- Choose the field control method to control the speed of the DC shunt motor and plot the field current v/s speed curve.
- Choose armature control method to control the speed of the DC shunt motor and plot the field current v/s speed curve.
- Apply Swinburne’s test on a DC shunt machine to predetermine its efficiency (when working as a motor and generator).
Module 4:
- Apply direct loading technique on a DC shunt motor to plot performance curves (torque vs speed, output vs efficiency, speed and input current)
- Plot the performance characteristics (torque vs speed, output vs efficiency, speed and input current) of a dc series motor by conducting direct load test
- Apply direct loading test on a DC compound motor and plot performance curves (torque vs speed, output vs efficiency, speed and input current).
