Question : 107 of 200

Marks: +1, -0

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.

420 V
230 V
500 V
210 V

Solution:

Generated EMF

\E _{ \g }={\ϕ\ZNP }/{60 \A }

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

\E _{ \g }={(0.01)(600)(700)(6)}/{60(2)}= 2 1 0 \V
