What is the role of the armature in a DC motor?

The armature in a DC motor plays a crucial role as it carries the current flowing through the motor and generates a magnetic field that interacts with the stationary magnetic field of the stator. This interaction between the magnetic fields leads to torque generation, which ultimately produces motion. Specifically, the armature consists of windings or coils of wire that, when energized, create a magnetic field that either attracts or repels the magnetic field of the stator. This combination of magnetic fields is what causes the rotor (connected to the armature) to turn, facilitating the motor's overall operation.

The other functions listed in the alternative options do not align with the primary purpose of the armature. While energy storage is important for various components in electrical systems, it is not a direct function of the armature. Regulating voltage is a task typically handled by controllers or additional circuitry in the system, rather than by the armature itself. Lastly, the conversion of AC to DC pertains to rectifier components or systems designed for that purpose, not to the armature of a DC motor. Therefore, the armature's primary responsibility is to carry current and create a magnetic field that enables motion.
