An armature is a framework or support structure used in various fields, including sculpture, electrical engineering, and robotics. In sculpture, an armature provides stability and shape to a piece, allowing artists to build up materials like clay or plaster around it. In electrical engineering, an armature refers to the rotating part of an electric machine, such as a motor or generator. It typically consists of coils of wire that generate a magnetic field when electric current flows through them, enabling the conversion of electrical energy into mechanical energy or vice versa.
