(c) The magnetization curve for a separately excited DC generator is shown in Figure Q4 (c). The generator is rated at 6 kW, 130 V, 50 A, and 1600 r/min. Its field circuit is rated at 5 A. The following data are known about the machine: RA = 0.18 N Radj = 0 to 40 N Np = 1000 turns per pole VF = 130 V Rp = 20 1 Answer the following questions about this generator, assuming no armature reaction. (ii) Analyze the maximum and minimum no-load voltages in the generator if the field rheostat is allowed to vary from 0 to 40 2 and the generator's speed is allowed to vary from 1400 to 2000 r/min. 160 150 140 130 120 110 100 90 80 70 60 50 40 30 20 10 Shunt field current, A 3000 Field mmf, A turms 1000 2000 4000 S000 6000 Terminal and generated voltuge, V
