Since the currents in the stator windings vary in step with the position of the rotor, an alternator is a synchronous generator.
The principle of operation of synchronous generator is electromagnetic induction. If there exits a relative motion between the flux and conductors, then an emf is induced in the conductors. To understand the synchronous generator working principle, let us consider two opposite magnetic poles in between them a rectangular coil or turn is placed ...

The Working Principle: RMF – Constant Magnetic field interaction ... Rotor of synchronous motor produces a constant magnetic field and Stator produces a Rotating magnetic field. ... This means zero current and force on squirrel cage bars, thus it will not affect synchronized operation of the motor. Synchronous motor out of Synchronism.
The working principle of alternator is very simple. It is just like basic principle of DC generator.It also depends upon Faraday's law of electromagnetic induction which says the current is induced in the conductor inside a magnetic field when there is a relative motion between that conductor and the magnetic field. For understanding working of alternator let us think about a single ...
