#Harmonics #PitchFactor #ElectricalMachine
This video is about mitigation of Harmonics in an Electrical Machine which can be done by two important aspects of machine designing, Pitch Factor and Distribution Factor. This is the first part of the complete topic, describing some important concepts like Pole Pitch, Coil Span, Full Pitched Coil, Short Pitched Coil, Pitch Factor and its role in the mitigation of an nth Harmonic EMF from the machine. The second part will focus on Distribution Factor and the related concepts.

Edit: Second part on Distribution Factor covered. Visit https://youtu.be/Zee8oZNMvbY
