An armature is a crucial component of an electric motor, serving as the rotating part of the machine.

It is composed of a cylindrical core of iron or steel, known as the rotor, with windings of insulated wire wrapped around it.

When a current is passed through these windings, a magnetic field is generated that causes the armature to rotate.

Armatures are commonly found in a variety of applications, such as power tools, appliances, and automobiles.

They come in various sizes and configurations to suit different motor designs and applications.
