Generators are classified as follows:
Generators are categorized into DC generators and AC generators;
AC generators are categorized into synchronous generators and asynchronous generators (rarely used);
AC generators can also be classified as single-phase or three-phase generators.
There are many types of generators. Based on operating principles, they are classified into synchronous, asynchronous, single-phase, and three-phase generators. Based on the method of generation, they include steam turbine generators, hydro-turbine generators, diesel generators, and gasoline generators. Based on the energy source, they include thermal power generators and hydroelectric generators.
