What is a generator alternator?

A generator alternator is the heart of the generator. The alternator also referred to as

genhead’ is that part of a generator that produces electrical energy from the mechanical

energy supplied to it by the engine.

An alternator comprises a stator -- a stationary component -- and a rotor -- a moving component.

When both the components work together a relative movement between the magnetic and

electric fields is generated which in turn produces electricity.

How does a generator alternator work?

The generator alternator works on the principle of electromagnetic induction.

According to this principle, when in the presence of a magnetic field an electrical conductor

such as a wire containing electric charges is moved, it results in a voltage difference

between the two ends of the electrical conductor which causes the movement of electric

charges through the wire, thereby generating electricity.

A generator alternator contains an assembly of both moving and stationary components encased in a protective housing.

The stationary part of the alternator, also known as ‘stator’ is a set of wires, or electrical conductors wound in coils over an iron core.

The rotor also known as the armature is the movable part of the alternator that produces the rotating magnetic field in three different ways.
