Determine I A , E A and the angle for the motor when the motor is outputting 20 hp assuming 0.75 PF lagging. d. Sketch the phasor diagrams for parts a, b and c. 4. Assuming that the motor is initially operating as indicated in problem 3a above. a. Determine I A , I L and the power factor if the load on the motor changes such that the motor is now outputting 35 hp. b. Sketch the phasor diagram for the operating conditions of part a. 5. The motor of problem 3 is connected in parallel with a 10 kW 0.8 PF lagging load. a. Determine I A , E A and the angle for the motor when the motor is outputting 20 hp if the combined load is to have a 1.0 PF b. Sketch the phasor diagram for the applied voltage, the total current and the currents through the two loads...
