  • armature reaction it means when the current is flowing in the armature winding then we know that it developed its own flux and also we know that according to lenz law it oppose the main flux make try to week then due to that the two effects are occurs 1:- demagnetising and cross magnetising effect due to these effect the MNA get shifted .

  • In simple...the armature flix affects the main flux...is called armature reaction

  • when an alternator is connected to a load, the load current is flowing through the armature windings. This armature current establish a flux in the air gap periphery, which effects the main field flux and known as armature reaction.

  • when current started following in armature then it reduces the net magnetic flux which is bad for machine so to again increase the magnetic field we apply a compensating winding and interpole winding......

  • effect of armature flux on main field flux is known as armature reaction. we know field winding of dc machine play vital role for over all operation. when both winding energised then armature winding give two effects on field winding i.e cross and demagnitizing effect. cross effect distorted field winding while demagnising effect reduce the voltage.

  • as tejaswi babu said armature reaction is defined as the effect of magnetic field on main field but may strengthens ,weakens or crossmagnetizes the main flux.

  • Armature reaction is nothing but the effect of armature field flux upon main field flux under the main field pole. Effect may be of two type cross magnetizing and demagnetizing. It will strengthen the flux or distort the flux

  • Due to current present in armature, a magnetic field is produced. This magnetic field is called Armature field flux. This flux interact with main flux in three ways. Either Magnetization or De-magnetization or Cross-magnetization. Each case has different effect on main flux. This whole reaction is called Armature Reaction. Or in simple words as Prabhat told, Armature reaction is the effect of armature field flux on main field flux.
