Tutorial: How to Perform NO LOAD & LOAD TEST AND SPEED CONTROL ON DC SHUNT MOTOR

Step 1: Introduction

• Watch the video titled "Electrical Machines | LAB - 3 | NO LOAD & LOAD TEST AND SPEED CONTROL ON DC SHUNT MOTOR" on the Engineering Devotion YouTube channel to understand the concepts of no-load test, load test, and speed control on a DC shunt motor.

Step 2: Set Up Equipment

• Gather the necessary equipment for the experiments, including a DC shunt motor, a power supply, a tachometer, and measuring instruments for voltage and current.

Step 3: Perform No-Load Test

• Connect the DC shunt motor to the power supply.
• Run the motor with no mechanical load applied.
• Measure and record the motor's speed, input voltage, input current, and power input.
• Calculate the no-load current and power factor of the motor.

Step 4: Perform Load Test

• Apply a mechanical load to the DC shunt motor.
• Measure and record the motor's speed, input voltage, input current, and power input under load conditions.
• Calculate the output power, mechanical power, and efficiency of the motor.

Step 5: Speed Control

• Implement speed control techniques on the DC shunt motor, such as field control or armature control.
• Adjust the field or armature resistance to control the speed of the motor.
• Measure and record the motor's speed and input parameters at different speed control settings.

Step 6: Analysis

• Analyze the data collected during the experiments to understand the performance characteristics of the DC shunt motor under different operating conditions.
• Compare the results of the no-load test, load test, and speed control experiments to draw conclusions about the motor's efficiency and speed control capabilities.

Step 7: Conclusion

• Summarize your findings and observations from the experiments.
• Reflect on the significance of performing no-load tests, load tests, and speed control experiments on DC shunt motors in practical applications.

By following these steps, you can learn how to perform no-load and load tests, as well as speed control experiments on a DC shunt motor to gain insights into its performance characteristics and operational capabilities.
