Explain armature reaction in dc generator
WebThe effect of Armature (stator) flux on the flux produced by the rotor field poles is called Armature Reaction. When the current flows through the armature winding of the alternator, a flux is produced by the resulting MMF. This armature flux reacts with the main pole flux, causing the resultant flux to become either less than or more than the ... WebFeb 24, 2012 · This results an armature current flux directed along the brush axis and causes cross magnetization of the main field. This cross …
