A 450-V. 60-Hz, three-phase, six poles, induction motor is drawing 90 A at 0.95 PF lagging. The stator copper losses are 1 kW. The friction and windage losses are 2000 W. the core losses are 4000 W, and the stray losses are negligible. Find the following quantities: A- The output power Pour B- The efficiency of the motor. C- Find the rotor current at full speed slip (S-0.08) if the rotor impedance Zr=20<40 2.
