Question
Download Solution PDFIn a DC generator, the number of poles and the number of armature conductors are fixed. Which of the following windings will give a higher EMF?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFArmature emf in a DC generator is given by,
\({E_g} = \frac{{\phi ZNP}}{{60A}}\)
ϕ is flux per pole
Z is the number of conductors
N is speed
P is poles
A is the number of parallel paths
For the lap winding, A = P
For the wave winding, A = 2
Hence armature emf is more with wave winding than with lap winding.Last updated on Jun 11, 2025
