DC generators are classified based on how their fields are excited (i.e. produced). There are three methods of excitation, and thus three main types of DC generators: Permanent Magnet DC Generators – Field
The DC generator uses the principle of energetically induced electromotive force. When the conductor reduces the magnetic flux, an EMF will be generated based on the electromagnetic induction principle of Faraday''s laws. The electromotive force produced when a conductor circuit is closed can cause the flow of current. DC Generator Working
A DC generator is defined as an electrical device that converts mechanical energy into direct current (DC) electricity. It works on the principle of electromagnetic induction, where an electric potential
Brushless generators carry a separate exciter and use magnetic induction between the exciter stator and the exciter rotor winding and a rectifier assembly to supply DC current to the main rotor winding. These machines work without the sliding ring and brush arrangement, thereby known as brushless alternators.

The current to create the electromagnetic field is direct current (DC) which can range from 50amps to 9000amps and more depending on the generator''s size. Modern excitation systems are static where DC current is created by rectifying AC power using saturable current transformers (SCTs) and power potential transformers (PPTs).
