1.
A 4 pole DC shunt generator generates 216 V when running at 600 rpm. The armature has 144 slots with 6 conductors each slot. Calculate Φ when its lap wounded.
Hint: More than 1 correct answer
a)
Number of poles = number of parallel path
b)
Number of conductors = 6
c)
flux per pole will be lesser when wound winding is applied
d)
Flux per pole = 25 mWb
