The word "armature" is commonly used in engineering and refers to the rotating part of a machine, typically a motor or dynamo. The pronunciation of this word is ˈɑːmətjʊə(r), with the stress on the second syllable. The "a" in the first syllable is pronounced as in "car" and the second syllable is pronounced as "mat" with a schwa sound at the end. The "e" at the end is silent. It's important to spell this word correctly to avoid confusion and misunderstandings in technical discussions.
An armature refers to a core or structure that supports or provides a framework for other components or materials in various systems or devices. It commonly consists of a solid or rigid piece that serves as a mounting or anchor for other parts, enabling their efficient operation.
In the context of electrical machines, such as electric motors or generators, an armature refers to the rotating part of the device. It is usually composed of a laminated iron core wrapped with insulated wire coils, known as the armature winding. The armature winding is responsible for generating a magnetic field when an electric current passes through it, which interacts with the stationary magnetic field produced by the stator, causing rotational motion.
Another application of the term armature can be found in the field of sculpture and model making. In this context, armature refers to a rigid supporting structure that provides stability to malleable materials like clay or wax during the sculpting process. It holds the shape of the sculpture or model and acts as a skeleton, allowing the artist to add and mold the material around it.
Overall, the term armature encompasses the central supportive component or structure in various systems, ranging from electrical machines to artistic creations. It plays a vital role in facilitating the functioning, stability, and shaping of different materials and applications.

The word "armature" comes from the Middle French word "armature" meaning "armor" or "equipment", which itself derived from the Latin word "armatura" with the same meaning. The Latin term originates from the verb "armare", meaning "to arm" or "to equip". The word "armature" was initially used to refer to the protective covering or armor of a knight or soldier. Over time, its meaning expanded to include other types of support or framework, such as the structure employed in electrical devices to support coils, windings, or other elements.
