Question 1: Why did we perform the no-load operation experiment for the asynchronous motor? Question 2:Why is the value of Cos phi small at no-load? Question 3: Find the cupper (Pcu), iron (Pfe) and frictional (Pfri) losses at no-load operation. What happens to cupper loss? Explain. Question 4:ls the calculated value of the Cos phi same with the measured value of Cos phi? Explain the reason if not. Question 5:Are the starting currents different for Y and A connections? Explain. Question 6:State your final observations about the experiment.
