A DC generator is a device that converts mechanical energy into direct current (DC) electrical energy. It operates on the principle of electromagnetic induction, where a conductor, such as a coil of wire, moves through a magnetic field, generating electricity. This process is commonly used in various applications, including battery charging and powering small devices. The main components of a DC generator include the rotor, stator, and commutator. The rotor, or armature, rotates within the magnetic field, while the stator provides the magnetic field. The commutator helps convert the alternating current generated in the rotor into direct current, making it suitable for use in electronic circuits.
