Direct Current Generator

Direct current generators, also known as DC generators, are devices that convert mechanical energy into direct current (DC) electrical energy. They are part of the supply class Generators And Generator Sets, Electrical, which falls under the supply group Electric Wire, And Power And Distribution Equipment.

DC generators consist of a rotor and a stator. The rotor is the rotating part of the generator, while the stator is the stationary part. The rotor is typically made up of a coil of wire wrapped around an iron core, which is connected to a shaft. The stator, on the other hand, contains a set of stationary magnets or electromagnets.

When the rotor is turned by an external mechanical force, such as an engine or a turbine, it creates a rotating magnetic field. This rotating magnetic field induces an electric current in the coil of wire on the rotor, which is then collected and transferred to an external circuit through brushes and slip rings.

DC generators are commonly used in various applications where a steady and constant supply of direct current is required. They are often used in automotive systems, battery charging, electroplating, and in some renewable energy systems.

It's important to note that DC generators are different from alternators, which produce alternating current (AC) instead of direct current.
