it is related to electrical system?is there any more effects
are available or only these two??

With the brushes in the G.N.A. position, there is only
cross-magnetizing effect of armature reaction. However, when
the brushes are shifted from the G.N.A. position, the
armature reaction will have both demagnetizing and cross
magnetizing effects.To neutralized the de-magnetizing
effects we add the more ampere-turns in the main windings
and foe cross magnetising effects we use compensating windings.
The second part is how it is related to electrical system?
These effects disturb our main magnetic field and ultimately
the fundamental behaviour of our DC machine. If the DC
machines are the part of electrical system then the positive
or negative effects influenced on these machine will also be
the part of electrical system, less or more.
At the extent of armature reaction only these two are else
nothing as per my knowledge.
