A motor starter.
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.
armature
The rotating coil of a dynamo or electric motor is called armature.

The distance between the two sides of an individual coil of and AC armature winding id termed the coil pitch.

They rotate the armature coil.
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)
Armature is a rotating part of the machine, the coil which wound in the core of that rotating part.
When power is applied to the armature coil, the armature which has the hammer attached to it is drawn into the coil. The bell is struck by the hammer. At the end of the hammer stroke there is a N.C. (normally closed) contact which is opened. The opening of the contacts stops the current flow to the armature coil and the armature and hammer return to the off bell position. In the off bell position the N.C. contact re closes and the cycle is repeated over again. This cycling will continue until the bell circuit is turned off.
