Question: A 24 slot, D.C. generator has 18 turns per coil in its armature lap winding. The field excitation is adjusted to 0.05Wb per pole and the armature angular velocity is 183.2 rad/sec. Determine:
a) the total induced emf
b) the induced emf per turn
c) the induced emf per coil, and
d) the induced emf per conductor
Here's my effort so far:
a) EMF=(2.Z.p.N.Φ)/60
p=1
Z=18x1 = 18
N=(183.2 / 2pi) x 60 = 1741 rev/min
Φ=0.05Wb
c=2
Total EMF induced = 52.23V ??
b) E = e(Z/c)
Induced EMF per turn=5.8V
c) ??????
d) e = (2NpΦ)/60
EMF per conductor = 2.9V
Can anybody please advise/correct my effort?
