Problem details: A 15 kW, 280V, 1200 rpm WASHING MACHINE needs to be fed by a generator in your home. You have a friend in a generator manufacturer company. He gave you different options and as you're studying in EE department, he asked you to choose the best one from those! The generator details are as shown in Table 01. No Type of Generator Separately Excited Shunt Series 1 2 3 4 5 Table 01: Data for different types of generators Armature Field Series resistance resistance Resistance (S2) (52) Long shunt Short shunt 0.4 0.6 0.8 1.2 1.4 120 140 160 180 2.2 2.4 2.6 Note: X, Y are the last two digits of your student ID.
