DC motors with skewed armature design - Control… Pittman Series 8000 brush-commutated dc motors feature a 7-slot skewed armature design to minimize magnetic cogging (reluctance torque) and promote smooth and quiet operation. Family of motors is suited for a wide range of power applications in data storage, medical, semiconductor... Armature Windings in Alternator & Types of Armature…

The effect of the armature field is to distort the generator field and shift the neutral plane. The neutral plane is the position where the armature windings are moving parallel to the magnetic flux lines, that is why an axis lying in this plane is called as magnetic neutral axis (MNA).

How Armatures Work - Armoto: Vintage Auto Electrical Rewinds

Abstract—The Skewing of rotor slots to eliminate the ill effects of slot harmonics causes a non-uniform distribution of flux density along the stack. It reduces the coupling between the stator and rotor mmfs introducing additional skew leakage. Three different equivalent circuits are derived from first principles... AW-1 Armature Winding Machine - Whitelegg armature… The armature can be held both with and without centralization of the axis. A guide hook covers thecommutator so that the wire insulation is not damaged as the armature is wound.The armature winding device is easily removed.
