No load test of 3-phase induction motor used to determine?

Question: No load test of 3-phase induction motor used to determine?

The no-load test of a three-phase induction motor is performed to determine several key parameters, including the rotational losses and magnetizing current of the motor. During the test, the motor is run at its rated voltage and frequency with no load attached to the shaft. The input power to the motor is then measured and used to calculate the copper losses and core losses of the motor. The magnetizing current can also be determined by measuring the current drawn by one of the phases of the motor. The results of the no-load test can be used to estimate the efficiency and power factor of the motor under various load conditions.
