    Hi. from what i have understood armature reactance in a generator for example is the reactance created due to the field of the rotor affecting the field from the stator. Is this correct?

    Armature reactance is the inductance associated with the armature winding.

    armature reactance is affected by the rotating field of the stator. As the reactance formula contains a frequency quantity, the armature reactance changes in relationship to the difference in frequency between the armature and stator fields.

    I think what you are referring to is called the "armature reaction," or back EMF, which is a phenomenon caused by flux coupling to the armature from the field. The armature reactance is the complex portion of the impedance of the armature winding due to its leakage inductance.

    Actually, I was looking at it from a motors point of view, so that info may not be useful.
