A 690-V, 60-Hz, 6-pole, Y-connected, 3-phase induction motor has the following parameters in ohms per phase: R1 = 0.3, X1 = 0.9, R2 = 0.6, X2 = 0.9, Rc = 1500, Xm = 600. The rotational loss is 5% of the power developed. When the motor runs at 7% slip, determine its 1) Input power 2) Airgap power 3) Developed power 4) Output power 5) Efficiency 6) Shaft torque.
