Alternator – operating principle

An alternator is an AC used to change mechanical energy into alternating current. Inside an alternator, electric current is produced in stator windings by the rotating magnetic field of a rotor. It is commonly used in mechanical vehicles as a source of electricity. Nowadays, alternators are digitally controlled so their quality control requires using state-of-the-art machinery.
