Harmonics in an Electrical Machine is a great problem as it affects the maximum torque in an AC motor and maximum generated EMF in case of an Alternator. Hence elimination or mitigation of Harmonics from the machine is important. This can be done by suitably designing the machine. One such design aspect is the Distribution Factor. This video shows how Distribution factor is effective in mitigating the Harmonics and how to calculate it for any order of Harmonics.

Another such design aspect is the Pitch Factor which I have covered explicitly in my earlier video.
