A long shunt compound generator delivers 50 A load at 500 V. Find induced e.mf. and the armature current. Assume Ra = 0.05 ohm, Rse = 0.03 ohm and Rsh = 250 ohms and brush drop of 1 V/brush. If flux per pole is 25 mWb with 250 number of armature conductors. Calculate the speed of the prime mover. The machine has six poles with the wave-type armature winding. If the same generator is connected as short shunt type, to supply the same load at the same voltage, at what speed should it be driven? (Ans.: 501.16 V, 52 A, 1619.71 r.p.m., 1619.52 r.p.m.)
