Armature Reaction in Alternator or Synchronous Generator

Armature Reaction at Resistive load

Armature Reaction: The effect of armature flux on the main field flux in any machine is known as armature reaction. In an Alternator, rotor is energized from a dc supply and made to rotate through the prime mover. When rotor rotates, rotating magnetic field of the rotor cuts the armature conductors and induces voltage (emf) … Read more
