question

Calculate the effect of armature reaction in a machine that is designed as follows: Series conductors per phase= 240 Slot width, a_3= - 0.504 in. Slot depth, b_c= 2.5 in. Pole pitch, \tau= 6.024 in. Axial length of stacking, L= 4.5 in. Number of stator slots, S_1= 144 Phases, m= 3 Poles, P= 24 Pitch, p= (5/6) or 0.833 Slot constant, K= (b_c / 3a_3) = 1.65 Frequency= 60 cycles The armature winding is made up of 10 conductors, each of 4 parallel straps per pole, connected for 2 parallel paths.
