(b) A 200 kW, 200 V, 4-pole, 800 rpm, separately excited DC generator is suggested to deliver the rated load at the rated voltage in a factory. The generator has the following details: Ra= 0.03 2, RF = 20 92, VF = 100 V, NF = 400 turns per pole, and Prot+Pcore= 8 kW. The demagnetising MMF due to armature reaction is 20% of the armature current. Its magnetisation curve is shown in Figure Q4(b). (i) Determine the induced EMF at full load. (ii) Identify the power developed. (iii) Discover the torque developed.
