What Does a Short Pitch Mean?

Short Pitch Coil
If the angular distances between the two coil sides are less than one pole pitch, it is termed short pitch or fractional pitch coil. The coil span or coil pitch for short or fractional pitch coil is less than 180 electrical degree. In such coils, the two coil sides are not under the poles.

What is the difference between full pitch and short pitch?

In a full pitch coil, the coil span will be 180° electrical ( equal to pole pitch ). In a short pitch coil, the coil span will be (180 - α)° electrical ( α = angle by which coils are short-pitched and always less than pole pitch ).

What are the advantages of short pitching?

All Answers (1) Advantages of short-pitched winding are: They save copper of end connection, They improve the wave-form of generated emf i.e generated emf can be made to approximate to a sine wave more easily and the distorting harmonics can be reduced or totally eliminated.
