II. Synchronous Generators

Armature Reaction in Synchronous Machines . Armature reaction. refers to • the influence on the magnetic field in the air gap when the phase windings a, b, and c on the stator are connected across a load. • The flux produced by the armature winding reacts with the flux set up by the poles on the rotor, causing the total flux to change.
