A 4 pole, lap wound, d.c. generators has 42 coils with 8 turns per coils. It is driven at 1120 r.p.m. If useful flux per pole is 21 mWb, calculate the generated e.m.f. Find the speed at which it is to be driven to generate the same e.m.f. as calculated above, with wave wound armature. H.W.4|| A 4 pole, lap wound 750 r.p.m. d.c. shunt generator has an armature resistance of 0.4 2 and field resistance of 200 S2. The armature has 720 conductors and the flux per pole is 30 mWb. If the load resistance is 15 2, determine the terminal voltage.
