What is the rotating part of an electrical generator known as?

The rotating part of an electrical generator is known as the rotor. The rotor is responsible for creating a magnetic field, which interacts with the stator (the stationary part of the generator) to produce electric current through electromagnetic induction. This process converts mechanical energy into electrical energy, allowing the generator to supply power.

The armature is often associated with the part of the generator that carries the current and may be part of the rotor in some designs, leading to some confusion. However, in the context of defining the rotating component specifically, the rotor is the more accurate term. The stator, on the other hand, is fixed and remains stationary, serving as the magnetic field provider. A blower is not relevant to generator operation, as it is typically associated with moving air or gas in various systems.
