purpose of steel core in stator of Alternator
There are three things wanted to produce electricity.
1.magnetic Field
2.Contactor
3.Motion/Rotation
But in practical generators have two magnetic field.means one in stator/armature,other in rotor/field.
“The magnetic core of coil is a better path for magnetic lines of force than is the nonmagnetic core of coil. The soft-iron magnetic core’s high permeability has less reluctance to the magnetic flux, resulting in more magnetic lines of force. This increase in the magnetic lines of force increases the number of lines of force cutting each loop of the coil, thus increasing the inductance of the coil.”
