Armature \Ar"ma*ture\, n. [L. armatura, fr. armare to arm: cf. F. armature. See Arm, v. t., Armor.]
Armor; whatever is worn or used for the protection and defense of the body, esp. the protective outfit of some animals and plants.
(Magnetism) A piece of soft iron used to connect the two poles of a magnet, or electro-magnet, in order to complete the circuit, or to receive and apply the magnetic force. In the ordinary horseshoe magnet, it serves to prevent the dissipation of the magnetic force.
(Arch.) Iron bars or framing employed for the consolidation of a building, as in sustaining slender columns, holding up canopies, etc.
--Oxf. Gloss.(Elec.) That moving part of a dynamo or electric generator in which a current is induced by a moving through a magnetic field, or, in an electric motor, the part through which the applied current moves, thereby generating torque. The armature usually consists of a series of coils or groups of insulated conductors surrounding a core of iron.
Douglas Harper's Etymology Dictionary
c.1400, "an armed force," from Latin armatura "armor, equipment," from armatus, past participle of armare "to arm, furnish with weapons" from arma (see arm (n.2)). Meaning "armor" is mid-15c.; that of "protective covering of a plant or animal" is from 1660s. Electromagnetic sense is from 1835.

Armature may refer to:
- Armature (electrical engineering), one of the two principal electrical components of an electromechanical machine.
- Armature (computer animation), the kinematic chains used in computer animation to simulate the motions of virtual characters.
- Armature (sculpture), a framework around which a sculpture is built.
- Armature Studio, a video game developer.
In sculpture, an armature is a framework around which the sculpture is built. This framework provides structure and stability, especially when a plastic material such as wax, newspaper or clay is being used as the medium. When sculpting the human figure, the armature is analogous to the major skeleton and has essentially the same purpose: to hold the body erect.
An armature is often made of heavy, dark aluminium wire which is stiff, but can be bent and twisted into shape without much difficulty. The wire is affixed to a base which is usually made of wood. The artist then begins fleshing out the sculpture by adding wax or clay over the wire. Depending on the material and technique, the armature may be left buried within the sculpture but, if the sculpture is to be hollowed out for firing, it must be removed.
Large representational sculptures meant for outdoor display are typically fashioned of bronze or other types of sheet metal, and they require armatures for internal support and stability. For example, a large armature designed by Gustave Eiffel holds up the Statue of Liberty. The armature can be seen from below by visitors to the base of the sculpture's interior.
In electrical engineering, an armature generally refers to one of the two principal electrical components of an electromechanical or electrical machine — generally in a motor or generator — but it may also mean the pole piece of a permanent magnet or electromagnet, or the moving iron part of a solenoid or relay.
The other component is the magnetic field ( magnetic flux) in the air-gap, which the armature interacts with, thus the field component can comprise either permanent magnets, or electromagnets formed by a conducting coil, such as another armature (i.e., Doubly-fed electric machine).
The armature, in contrast, must carry current, so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, torque (rotating machine), or force (linear machine). The armature's role is twofold. The first is to carry current crossing the field, thus creating shaft torque in a rotating machine or force in a linear machine. The second role is to generate an electromotive force (EMF).
In the armature, an electromotive force is created by the relative motion of the armature and the field. When the machine acts in the motor mode, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque (unless the machine is stalled), and transfers it to the load via the shaft. When the machine acts in the generator mode, the armature EMF drives the armature current, and shaft mechanical power is converted to electrical power and transferred to the load. In an induction generator, these distinctions are blurred, since the generated power is drawn from the stator, which would normally be considered the field.
A growler is used to check the armature for shorts, opens and grounds.
An armature is the name of the kinematic chains used in computer animation to simulate the motions of virtual human or animal characters. In the context of animation, the inverse kinematics of the armature is the most relevant computational algorithm.
There are two types of digital armatures: Keyframing (stop-motion) armatures and real-time (puppeteering) armatures. Keyframing armatures were initially developed to assist in animating digital characters without basing the movement on a live performance. The animator poses a device manually for each keyframe, while the character in the animation is set up with a mechanical structure equivalent to the armature. The device is connected to the animation software through a driver program and each move is recorded for a particular frame in time. Real-time armatures are similar, but they are puppeteered by one or more people and captured in real-time.
