A 8 pole, DC generator has a simplex wave wound armature containing 32 coils of 6 turns each. It flux/pole is 0.06 wb.The machine is running at 250 rpm, calculate the induced armature voltage. (GATE-EE-2004)
Given:
P=8, DC gen,Wave(A=2),Coils C=32, turns per coil = 6, flux ø= 0.06 wb, speed N=250 rpm
EMF E=?
Solution:
E=øZNP/60A , Turns T= coils * turns per coil =32*6= 192
Z=2T= 2*192 = 384 conductors
E = 0.06*384*250*8 / 60*2
Ans : E=384 volts
