What is defined as the rotating conductor of an exciter?

The term that defines the rotating conductor of an exciter is the armature. In excitation systems, the armature is a crucial component that converts mechanical energy into electrical energy. It consists of winding wires that are mounted on a rotating core, which moves through a magnetic field generated by the field windings. As the armature rotates, it induces an electromotive force (EMF) according to Faraday’s law of electromagnetic induction.

The armature operates in conjunction with the other components of the exciter. For instance, the field windings provide the magnetic field needed for the armature to function effectively. The rotor shaft connects to the armature, providing the necessary mechanical rotation, but it does not carry out the electrical functions of generating voltage. The voltage regulator is responsible for controlling the output voltage from the exciter but does not partake in the generation itself. Thus, understanding the intimate relationship between these components clarifies why the armature is recognized as the rotating conductor within the excitation process.
