Tell me 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.
