A four-pole motor has a wave-connected armature with 888 conductors. The brushes are displaced backwards through 5 angular degrees from the geometrical neutral. If the total armature current is 90 A, calculate:
(a) the cross and the back ampere-turns per pole;
(b) the additional field current to neutralize this demagnetization, if the field winding has 1200 turns per pole.
