Answer / bob
armature indused flux cause influance on field flux so the
Magnetic Neutral axis will be shifted and spark appear on
carbon brashes

Answer / aday9
Armature reaction is the interaction between flux set-up by the current carrying armature conductors with the main field flux.The entire energy conversions from mechanical to electrical in the case of generator, and electrical to mechanical in the case of motors takes place only due to this interaction.

Answer / rolly
weakening and distorting main field flux by the flux
produced by armatures is known as armature reactions.it
will produce problems in commutation.

Answer / engr. irfan jamil
If the magnetic field windings of a DC machine are
connected to a power supply and the rotor of the machine is
turned by an external source of mechanical power then a
voltage will be induced in the conductors of the rotor. If
a load is connected to the terminals of the machine a
current will flow in the armature (rotor) windings. This
current will produce a magnetic field of its own , which
will distort the original magnetic field from the machine's
poles. This distortion of the flux in a machine as the load
is increased is called ARMATURE REACTION. This armature
reaction causes two main problems in DC machines: neutral-
plane shift and flux weakening.
