armature
Noun: 1. The rotating part of an electric motor or generator: In electrical engineering, an armature is the coil or winding in which an electric current is induced by its motion through a magnetic field. It is the central, moving component that converts electrical energy to mechanical energy (in a motor) or mechanical energy to electrical energy (in a generator). 2. A framework serving as a core or support: In sculpture and modeling, an armature is a rigid internal framework, often made of wire or metal, used to support the soft material (like clay or plaster) being shaped. 3. (Archaic) Defensive covering; armor: This older meaning refers to a protective covering, such as a suit of armor or a protective shell on an animal.
- Electrical Engineering:
- The mechanic replaced the worn brushes that were in contact with the motor's armature.
- Voltage is generated in the armature as it spins within the stator's magnetic field.
- Art and Sculpture:
- Before adding the clay, the artist built a sturdy wire armature to define the figure's pose.
- A strong armature is essential to prevent a large sculpture from collapsing under its own weight.
- "Armature reaction": In electrical machines, this refers to the effect where the magnetic field produced by the current in the armature winding distorts or weakens the main magnetic field from the field magnets.
- Armatured (adj): Fitted with or having an armature.
- The armatured sculpture was ready for the application of wet clay.
- Armature Winding (n): The specific arrangement of insulated coils that form the armature in an electrical machine.
- Core (for the framework meaning).
- Framework.
- Structure.
- Rotor (specifically for the rotating armature in many motors/generators).
- Armor (for the archaic meaning).
- Armature coil: The specific loop or loops of wire within the armature.
- Armature shaft: The central axle on which the armature rotates.
-
coil in which voltage is induced by motion through a magnetic field
