Alternator Principle

The alternator work on the principle of Electromagnetic induction. When there is relative motion between the conduction and the flux., Emf get induced in the conductors. The only difference in the practical sync. Generator & DC generator is that in an alternator the conductors are stationery and field is rotating. The rotor of an alternator or a synch. Generator is mechanically coupled to the shaft on the turbine blades. Which is made to rotate at synch. Speed Ns under Mech Force.
