The rated speed of a 6-pole, 9000 W, 400V, 60 Hz, Y connected, 3-phase Induction motor is 1150 rpm on full load. The stator copper loss is 260 W, and rotational losses assumed to be constant at 370 W. The motor is running with a power factor: cos$=0.82. Determine: The power developed, the airgap power and the rotor copper loss, the input power, The efficiency, the stator current and the shaft torque. c) Draw and label the power diagram of the induction motor for this problem. b)
