Armature Windings

AC Winding

AC Winding: Ac winding are generally of a 3-phase kind because of the inherent advantages of a 3-phase machine. The armature coils must be connected to yield balanced (equal in magnitude and successive phase difference of 2π/3 rad) 3-phase emfs. To begin with the slots around the armature periphery must be divided into phase-bands. Phase …
