Question: Question 7 A three - phase, 4 - pole, 2 2 0 VLL , 3 2 HP , 6 0 Hz , wye - connected

Question 7
A three-phase, 4-pole, 220 VLL,32 HP,60 Hz, wye-connected induction motor draws a current of 77 A, from the line source at a PF of 0.87 lagging. The slip is s =0.06. At these operating points, we have the stator copper loss, Pscl =1,049 W and the core loss, Pc =442 W. Rotational losses are 540W.
Find the actual shaft output in HP(1 HP =735.5 W).
