Question 3 A 500-V, 37.3 kW, 1000 r.p.m. d.c. shunt motor has full-load efficiency of 90 percent. The armature circuit resistance is 0.2452, and there is a total voltage drop of 2 V at the brushes; the field current is 1.8 A. Determine (i) (ii) (iii) full-load line current full load shaft torque in N-m and total resistance in motor starter to limit the starting current to 1.5 times the full- load current.
