Calculate the number of conductors on each pole piece required in a compensating winding for a 6-pole lap-wound dc armature containing 286 conductors. The compensating winding carries full armature current. Assume ratio of pole arc/ pole pitch = 0.7.

Calculate the number of conductors on each pole piece required in a compensating winding for a 6-pole lap-wound dc armature containing 286 conductors. The compensating winding carries full armature current. Assume ratio of pole arc/ pole pitch = 0.7. Correct Answer 6

The number of ampere-turns required for compensating winding is ATcw /pole = ATa (peak) *(pole arc/pole pitch) = * (pole arc/pole pitch). Ncw/pole = (Z/2AP) * (pole arc/pole pitch) = 0.7 = 2.78. Compensating conductors/pole = 2 * 2.78 = 6 (nearest integer).
