Generator Armature-Rotor

A generator armature-rotor is a key component of an electric generator. It is responsible for converting mechanical energy into electrical energy. The armature-rotor consists of a cylindrical core made of laminated iron or steel, which is mounted on a shaft and rotates within the generator's stator.

The armature-rotor is typically equipped with a series of windings or coils, which are connected to the external circuit. These windings are usually made of copper wire and are arranged in a specific pattern to generate a magnetic field when an electric current flows through them.

As the armature-rotor rotates within the stator, the magnetic field generated by the windings interacts with the stationary magnetic field produced by the stator. This interaction induces an electric current in the armature windings, which is then collected and transferred to the external circuit through brushes and slip rings.

The rotation of the armature-rotor is usually driven by an external power source, such as a turbine or an engine. As the rotor spins, it generates electrical energy that can be used to power various devices or be fed back into the electrical grid.

In summary, the generator armature-rotor is a crucial component that converts mechanical energy into electrical energy by utilizing the principles of electromagnetic induction.
