How to find short pitch and pole pairs of motors

  1. Oct 15, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    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.
