A bipolar dc machine with interpoles has a main-pole flux of ф per pole and an interpole flux of Фᵢ per pole.
The yoke of the machine is divide into four quadrants by the main-pole axis and the commutation axis.
The flux-distribution in the quadrants will be
A. ½ ( ф + фᵢ ) in all the four quadrants
B. ½ ( ф - фᵢ ) in all the four quadrants
C. ½ ( ф + фᵢ ) in two diametrically opposite quadrants and ½ ( ф - фᵢ ) in the remaining two Quadrants
D. ½ ( ф + фᵢ ) in two adjacent quadrants and ½ ( ф - фᵢ ) in the remaining two quadrants
