Due to the different energy forms, can be made into different generators. In the case of
The use of water resources and turbine with, can be made of hydro-generators; due to reservoir capacity and the difference between the level of different water, can be made of different capacity and speed of the hydro-generator. The use of coal, oil and other resources, and boilers, turbine steam engine with, can be made of turbo-generator, this generator is mostly high-speed motor (3000rpm). In addition there are the use of wind energy, atomic energy, geothermal, tidal energy and other types of generators. The use of diesel, gasoline and other resources as energy diesel, gasoline generators used more widely. In addition, due to the different working principle of the generator is divided into DC generators, asynchronous generators and synchronous generators. Currently widely used generators are synchronous generators.
