Explain about the size of armature slots
This distance is measured in term of armature slots or armature conductor come between two adjacent pole centers. ... If the coil span is equal to the pole pitch, then the armature winding is said to be full – pitched.
Each armature slot is partitioned into two layers, a top layer and a bottom layer. The winding is called as a double layer winding.of a slot which is displaced by about one pole pitch. The junction of two coils is terminated on a commutator segment. Thus there are as many commutator segments as the... Full text of "Armature winding and motor repair; practical… Numbering Coil Sides in Armature Slots . .Tools for Undercutting Mica Size of Circular Saw Required Finishing Slots and Commutator Surface after Undercutting Brushes for Use on Undercut .In what follows these terms are explained. In most cases they are used alike both in windings for... Armature Windings, Number of Conductors, Types of Slots |… The armature winding can broadly be classified as concentrated and distributed winding. In case of a concentrated windingSince for a given number of conductors, poles and slots, a single layer winding calls for less 2 number of coils of more number of turns, reactance voltage proportional to (turn) is high. “Equalizer connection is needed in lap winding armature…

Pole Pitch is naturally equal to the total number of armature slots divided by the number of poles in the machine. If there are 96 slots on the armature periphery and 4 numbers of poles in the machine, the numbers of armature slots come between two adjacent poles centres would be 96/4 = 24.
