Alternator Rotor and Stator Function Explained

How the Alternator Rotor Functions

The basic element of the rotor consists of iron as the core and copper winding over this core. It also consists of two slip rings and two claw-pole assemblies.
The rotation of the rotor is carried out by a drive belt integrated with the vehicle fuel engine. The rotation of the rotor cuts the coils of the stator with alternating north and south magnetic fluxes.

This operation induces alternating current corresponding to the changing magnetic flux into the stator winding.
The induced current is directly proportional to the strength of the rotor magnetic flux which in turn depends on the strength of the current introduced into the rotor winding externally.

How the Alternator Stator Functions

 The stator basically consists of three groups of windings. Each group is positioned slightly at a different angle to the preceding one which gives rise to three intersecting AC sine phases which are 120 degrees apart from each other.
Together, the three phases constitutes the AC output from the alternator. Inclusion of three phases provides better current response.
The core over which the above three windings are wound is made up of laminated iron strips which results better magnetic concentration and thus the torque.
The windings are fundamentally of types, the Delta and the Wye. In Delta type of winding, only three leads terminate out, each having equal sets of wiring.
