A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by turbines such as water turbines, steam turbines, diesel engines, or other power machinery. These turbines convert the energy from flowing water, air currents, fuel combustion, or nuclear fission into mechanical energy, which is then transmitted to the generator. The generator then converts this mechanical energy into electrical energy.

Generators have a wide range of applications in industrial and agricultural production, technology, and daily life. There are many types of generators, but their working principle is based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of their construction is to use appropriate magnetic and conductive materials to form magnetic and electrical circuits that induce each other, in order to generate electromagnetic power and achieve the purpose of energy conversion.
