A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%. A) Calculate the starting current. (ignore the magnetizing current) B)Determine the starting torque. C) Determine the maximum torque D) Calculate the value of the resistance that should be added to the rotor circuit to reduce the starting current by 50% E) What is the starting torque in part (D) F)Calculate the value of the resistance that should be added to the rotor circuit to increase the starting torque to maximum. G) What is the starting current in part (F)
