Armature Reaction

Armature Reaction: When the armature of a dc machine carries current, the distributed armature winding produces its own mmf (distributed) known as armature reaction. The machine air-gap is now acted upon by the resultant mmf distribution caused by simultaneous action of the field ampere-turns (AT f)and armature ampere-turns (ATa). As a result the air-gap flux […]
