Induction Motor Parameter Estimation Kit (No-Load and Blocked-Rotor Tests)

Approx. component budget: Rs. 6,000 - 11,000

Objective

Carry out no-load and blocked-rotor tests, find the equivalent circuit parameters and predict performance, then compare it with a direct load test.

What you will build

A small single-phase or three-phase induction motor with a variac, voltage and current sensors, a wattmeter module, a mechanical brake or loading arrangement and a logger.

Results you can expect

• Equivalent circuit values
• Predicted vs measured efficiency and slip
• Torque-speed curve
• Power factor vs load

What you will learn

Induction motor theory, standard test methods and equivalent circuits, useful for motor testing and maintenance work.

Tools and notes

Arduino/ESP32 with sensors, variac, tachometer, Excel. Blocked-rotor test is done at reduced voltage for a short time only. Connects to mains, so use supervision.

Resume points from this project

• Built and tested Induction Motor Parameter Estimation Kit (No-Load and Blocked-Rotor Tests); objective: carry out no-load and blocked-rotor tests, find the equivalent circuit parameters and predict performance, then compare it with a direct load test.
• Measured and analysed equivalent circuit values and predicted vs measured efficiency and slip; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
