Chorded Coils: Exploring the Intricacies of Fractional Pitch
Short Pitch and Fractional Pitch Defined
In the realm of electrical engineering, the concept of coil pitch plays a crucial role in determining the behavior and performance of electrical machines. When the angular distance between the two coil sides of an electrical coil is less than one pole pitch, it is known as a short pitch or fractional pitch.
Chorded Angle and Chorded Coils
For a short pitched coil, the angle by which the coil span departs from a pole pitch is referred to as the chording angle or ΞΎ (xi). A short pitched coil is also known as a "chorded coil." This design choice imparts unique characteristics to the coil.
