Pole core and pole shoe

The pole cores are made of steel laminations that are insulated from each other and riveted together. Every pole core has a pole shoe having a curved surface. The functions of pole shoe are

(i)  To support the ?eld coil and

(ii)  To enhance the cross sectional area of the magnetic circuit and

(iii)  To decrease its reluctance.
