C. Cumulatively compounded short shunt
D. Differentially compounded short shunt
A. Demagnetization only
B. Cross magnetization as well as magnetization
C. Cross-magnetization as well as demagnetizing
D. Cross magnetization only
POLE PITCH= NO: OF CONDUCTORS/ NO: OF POLES
= 32 / 4
POLE PITCH = 8 ANSWER
NO: OF CONDUCTORS = NO: OF COIL * LAYER
= 16 * 2 = 32
And 4 .in case of double layer wind no of coil=no of slot.
Pitch fac=slot per pole
=16/4=4
Pp = 2*no of conductor/pole
