Answer» 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 coils excited by permanent magnetsSeparately Excited DC Generators – Field coils excited by some external sourceSelf Excited DC Generators – Field coils excited by the generator itselfSelf-excited DC generators can further be classified depending on the position of their field coils. The three types of self-excited DC generators are:SERIES WOUND GeneratorsShunt Wound GeneratorsCompound Wound GeneratorsA PORTABLE generator is an example of a practical application that utilises such technologies.
