An armature in a motor is defined as rotating part of a motor that emits electric energy into a magnetic field.
An armature is made of wire coiled around a metal core. An electric current is produced in this metal core that interacts with an input current to produce torque, the mechanism that causes a vehicle to accelerate.
In electrical engineering, an armature is classified as the part of an alternator, motor or generator that produces power. In mechanical engineering, the armature is either the rotating or static component of a motor, alternator or generator.
The armature operates by rotating along with a magnetic field. The armature will rest when the resultant field is aligned with the stator (or static) field. The direction of the current in an armature may or may not change, depending on the position of its resultant field.
