Generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other power machinery, which converts the energy generated by water flow, airflow, fuel combustion or atomic fission into mechanical energy to the generator, which is then converted into electrical energy.
Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their working principles are based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: the use of appropriate magnetic and conductive materials to form a magnetic circuit and circuit for mutual electromagnetic induction, in order to generate electromagnetic power to achieve the purpose of energy conversion.
Generators are usually composed of stator, rotor, end caps and bearings.
The stator consists of the stator core, wire windings, seat and other structural parts that hold these parts in place.
The rotor consists of the rotor core (or pole and choke) winding, guard ring, center ring, slip ring, fan and shaft.
The stator and rotor of the generator are connected and assembled by bearings and end caps, so that the rotor can rotate in the stator and do the movement of cutting magnetic lines of force, thus generating the induced potential, which is led through the terminals and connected in the circuit, then the current is generated.
