(i) An induction motor draws 25 A from a 460 V, three-phase line at a power factor of 0.85, lagging. The stator copper loss is 1000 W, and the rotor copper loss is 500 W. The friction, loss is 250 W, core loss is 800 W, and stray loss is 200 W. Calculate a. the air-gap power, b. the developed mechanical power, c. the output horsepower, d. and the efficiency. (ii) If the frequency of the source in part (i) is 60 Hz, and the machine has four poles, find e. the slip, f. the operating speed, g. the developed torque, h. and the output torque.
