Do you know armature reaction?
Submitted by: MuhammadArmature 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
a. It demagnetizes or weakens the main flux
b. It cross-magnetizes or distorts it.
The first effect leads to reduced generated voltage and second to the sparking at the brushes.
