Generators are classified into two main types based on the way in which their fields are excited:
1. Self-excited generators: In self-excited generators, the field winding is connected directly to the output of the generator. This means that the generator produces its own magnetic field without the need for an external power source. Self-excited generators can further be divided into two subtypes:
- Permanent magnet generators: These generators use permanent magnets to create the magnetic field within the generator. They are simple and reliable but may not be suitable for high-power applications.
- Self-excited DC generators: These generators use the output voltage from the generator itself to create the magnetic field. They are commonly used in small-scale applications.
2. Separately excited generators: In separately excited generators, the field winding is connected to an external power source, such as a battery or another generator. This external power source supplies the necessary current to create the magnetic field within the generator. Separately excited generators are more commonly used in larger-scale applications where precise control over the output voltage is required.
