The classification of generators includes:
Generator Division: DC generator and AC generator;
Alternator: synchronous generator and asynchronous generator (rarely used);
Alternator can be divided into single phase generator and three-phase generator.
There are many kinds of generators. In principle, it is divided into synchronous generator, asynchronous generator, single phase generator and three-phase generator. It can be divided into steam turbine generator, hydrogenerator, diesel generator, gasoline generator and so on. From energy, it is divided into thermal power generator, hydraulic generator and so on.
