Detailed Solution
Concept:
Induced emf in a generator is given by
Where,
N = speed in rpm
P = no of pole
ϕ = flux per pole
A = 2 for wave winding
= P for lap winding
Z = number of conductors
Calculation:
Given that,
Total number of conductors (Z) = slots × conductors per each slot
⇒ Z= 51 × 20 =1020
P = 4
ϕ = 0.007 wb
A = 4
N = 1500 rpm
