WebThe effect of armature (stator) flux on the flux produced by the rotor field poles is called armature reaction. It depends on the power factor i.e. the phase relationship between the terminal voltage and armature current. At lagging power factor load, the armature reaction is partly demagnetizing and partly cross-magnetizing; At zero power ...
