q4 c 

(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 lield circuit is rated at 5 A. The following data are known about the machine: RA = 0.18 N Radj = 0 to 40 N NF = 1000 turns per pole VF = 130 V Rp = 20 N Answer the following questions about this generator, assuming no armature recaction. (i) Determine the range of voltage adjustments that can be achieved by changing Radj if this generator is operating at no load. 160 150 140 130 120 110 100 90 80 70 60 50 40 30 20 10 6.
