Do You Know Armature Reaction?

1.	Do You Know Armature Reaction?
Answer» ARMATURE reaction is the effect of magnetic field setup by armature current on the distribution of flux under MAIN poles of a generator. The armature magnetic field has two effects It demagnetizes or weakens the main flux It cross-magnetizes or distorts it. The FIRST effect leads to REDUCED generated voltage and SECOND to the sparking at the brushes.

ARMATURE reaction is the effect of magnetic field setup by armature current on the distribution of flux under MAIN poles of a generator. The armature magnetic field has two effects

It demagnetizes or weakens the main flux
It cross-magnetizes or distorts it.

The FIRST effect leads to REDUCED generated voltage and SECOND to the sparking at the brushes.
