Final answer:
To determine the input power of the stator of a 3-phase induction motor, we need to know the synchronous speed of the motor. This can be calculated using the formula Ns = (120 * f) / P. Once we have the synchronous speed, the input power can be calculated using the formula Input Power = (Ns / 1000) * (3-phase line current) * (3 * √3) * (stator resistance). However, more information is needed based on the given question.
Step-by-step explanation:
To determine the input power of the stator, we need to know the synchronous speed (Ns) of the motor. The synchronous speed can be calculated using the formula:
Ns = (120 * f) / P
Where Ns is the synchronous speed, f is the frequency of the power supply in hertz (Hz), and P is the number of poles of the motor.
Once we have the synchronous speed, we can calculate the input power of the stator using the formula:
Input Power = (Ns / 1000) * (3-phase line current) * (3 * √3) * (stator resistance)
Where √3 is the square root of 3 and stator resistance is the resistance of each phase of the stator winding. However, since the question mentions the rotating speed of the magnetic field of the stator (not the synchronous speed), we would need more information or clarification to provide an accurate answer.
