1. The problem statement, all variables and given/known data 2. Relevant equations p=nsf δ=mϒ Kd=[sin(δ/2)]/msin(γ/2) Kp=cosε/2 e.m.f=4.44TφfKdKp 3. The attempt at a solution i do not know why pole pair =2 and it is short 2 pitch. how can i find pole pair and short pitch from its original developed diagram? i know that Phase spread=60(we choose) So for narrow spread ,the pattern is A-CB-AC-B for m=2 for each phase it have 2 slot.
