Explanation: The fractional pitch winding results in reduction of copper in overhang and it results in less cost of the machine. kpn=cos(nε)/2 implies reduces harmonics and thereby rendering the output EMF wave almost a sine wave. 10. The pitch factor, in rotating electrical machinery, is defined as the ratio of resultant EMF of a
