An “armature” can refer to several different components depending on the context:
- Relay, Regulator, Horn, etc.: The movable part of the unit that responds to electric current, typically to actuate or control a mechanism.
- Magnetic Application: A piece of low-reluctance ferromagnetic material (often called a keeper) used to bridge the poles of a permanent magnet temporarily, reducing the leakage field and preserving magnetization.
- Starter or Generator: The rotating part between the pole shoes, consisting of wire windings (often copper) on an iron core or axle. When the armature rotates, it induces an electric current.
- Electric Motor or Generator: The part moved by magnetism within these devices, consisting of wire windings on an iron core, responsible for generating or receiving electrical energy.
- Model Making: The supporting structure (wooden, metal, or hard-foam) under a clay model, used in sculpture or prototyping.
Each definition highlights the versatility of the term “armature” across different fields of technology, engineering, and art.
