A Three-phase four-pole AC machine has 60 coils in the stator and each coil has 100 turns. The coils are place in 60 uniformly distributed slots around the inner perimeter of the stator. The coil is also short-pitched (eg spam of two sides of one coil is 13 slots, less than the pole-pitch). The distribution factor of the phase winding is 0.9566 and the short pitch factor is 0.97814. What is the winding factor of the phase winding, and the effective number of turns for each phase winding.
