Armature Reaction in Alternator or Synchronous Machine

Armature winding in an electrical machine is the winding which carries the load current. Under no-load condition, the armature current is zero. But as the machine is loaded, load current flows through the armature winding and creates magnetic flux. The effect of armature winding mmf or flux on the main working flux created by field … Read more

Detrimental Effects of Armature Reaction

As discussed in earlier post, Purpose of Interpole in DC Machine, there are two types of effect of armature mmf on the main field flux: 1)      Distortion in Main Field Flux 2)      Net reduction of Main Field Flux Due to the above two effects of armature mmf, there are many detrimental effects on the Electrical … Read more
