Question

9.4.) A 10-hp, 4-pole, 440-V, 60-Hz, Y-connected, three-phase induction motor
runs at 1725 rpm on full load. The stator copper loss is 212 W, and the
rotational loss is 340 W. Determine (a) the power developed, (b) the air-
gap power, (c) the rotor copper loss, (d) the total power input, and (e) the
efficiency of the motor. What is the shaft torque?

9.5.) A 2-hp, 120-V, 60-Hz, 4-pole, Y-connected, three-phase induction motor
operates at 1650 rpm on full load. The rotor impedance at standstill is 0.02
+ j0.06 Rlphase. Determine the rotor current if the rotational loss is 160 W.
What is the magnitude of the induced emf in the rotor?
