armature,

in art: see sculpturesculpture,
art of producing in three dimensions representations of natural or imagined forms. It includes sculpture in the round, which can be viewed from any direction, as well as incised relief, in which the lines are cut into a flat surface.

Armature

 

a set of auxiliary, usually standard, mechanisms and components that are not basic parts of a machine, structure, or building but that ensure its proper functioning.

There are several types of armatures, including pipe fittings (for water, steam, gas, fuel, and various products processed in the chemical, food, and other industries). Depending on their function, pipe fittings are called shutoff fittings (faucets and slide valves); safety fittings (valves); control fittings (valves and pressure regulators); outlet fittings (air outlets and condensation outlets); emergency fittings (signal horns); and others.

The armatures used in electrical machine building are current-conducting and auxiliary parts securely attached to the rotor of an electrical machine. Armatures in electrical systems include panels, sockets, switches, plugs, and others. In electrical lines armatures are parts and devices for attaching insulators to supports (poles) and conductors to insulators. In lighting engineering, armatures are the parts of light fixtures designed to distribute the luminous flux, protect the eyes from bright light rays, deliver the electric current, reinforce the lamp, protect it from damage, and so forth. Furnace fittings (used in metallurgical furnaces) are metal parts that increase the strength of the furnace and cool its outer surfaces.

Armature

 

the rotating part of an electric machine. The term “armature,” as opposed to “rotor,” is usually used for DC machines. An armature includes a magnetic core that consists of laminated sheets of electrical steel that are insulated from each other by varnish or paper. A winding is placed in slots on the core and is connected to the commutator bars.

armature

[′är·mə‚chər]
(architecture)
Framing or bars fashioned of structural ironwork and used to reinforce various features, for example, slender columns or hanging members.
(electromagnetism)
That part of an electric rotating machine that includes the main current-carrying winding in which the electromotive force produced by magnetic flux rotation is induced; it may be rotating or stationary.
The movable part of an electromagnetic device, such as the movable iron part of a relay, or the spring-mounted iron part of a vibrator or buzzer.

Armature

That part of an electric rotating machine which includes the main current-carrying winding. The armature winding is the winding in which the electromotive force (emf) produced by magnetic flux rotation is induced. In electric motors this emf is known as the counterelectromotive force.

On machines with commutators, the armature is normally the rotating member. On most ac machines, the armature is the stationary member and is called the stator. The core of the armature is generally constructed of steel or soft iron to provide a good magnetic path, and is usually laminated to reduce eddy currents. The armature windings are placed in slots on the surface of the core. On machines with commutators, the armature winding is connected to the commutator bars. On ac machines with stationary armatures, the armature winding is connected directly to the line. See Core loss, Windings in electric machinery

armature

1. The heavy-current winding of a motor or generator.
2. The winding in a solenoid or relay.
3. Structural ironwork in the form of framing or bars (commonly employed in medieval buildings) used to reinforce slender columns, or to consolidate canopies or hanging members such as bosses, and in tracery.
