A 6 -pole, wave-wound armature has 600 conductors and is driven at 700 rpm. Determine the generated EMF in the armature if the flux per pole is 10 mWb.
A 6-pole wave-wound armature has 600 conductors and is driven at 700 rpm. Determine the generated EMF in the armature if the flux per pole is 10 mWb.
Right Answer is:
210 V
SOLUTION
Given
Number poles P = 6
Conductors Z = 600
Speed N = 700 rpm
The flux per pole (ϕ) = 0.01 Wb
As winding is wave type
Number of parallel paths A = 2
EMF equation of Generator
${E_g} = \dfrac{{\phi ZNP}}{{60A}}$
${E_g} = \frac{{(0.01)(600)(700)(6)}}{{60(2)}}$
Eg = 210 V
