How many types of generators are there

The classification of generators includes:
Generator points: DC generator and alternator;
Alternator points: synchronous generator and asynchronous generator (rarely used);
Alternators can also be divided into single-phase generators and three-phase generators.
There are many types of generators. In principle, it is divided into synchronous generator, asynchronous generator, single-phase generator and three-phase generator. In terms of production methods, it is divided into steam turbine generators, water turbine generators, diesel generators, gasoline generators, etc. In terms of energy, it is divided into thermal power generators, hydropower generators, etc.
