Unformatted text preview: the distance between the coils and k is the order of the harmonic MMF that is being considered. coil x y z β k p k d k w N s N s nMMF MMF dist M conc k dk = k dk k n α 2 sin n k α 2 sin= α b) The basic objective in the pitch factor analysis is to determine the effect of taking a concentrated winding with turns, and having it not span a complete pole pitch, but rather short pitching it by degrees (see figure above). Show that the of the short pitch winding is related to the MMF of the full pitch winding by the factor (3) where (4) and is the pitch angle and k is the order of the harmonic.
