The working principle of the power generator is based on the law of electromagnetic induction, which is the process of converting mechanical energy into electrical energy. The following is a detailed explanation of the working principle of the generator:
1、 The basic structure of the power generator
The power generator is mainly composed of two parts: stator and rotor
Stator: The stator is a fixed part of the power generator, usually composed of an iron core and coils (windings) wound around the iron core. These coils are used to generate induced electromotive force.
Rotor: The rotor is the rotating part of a generator, usually composed of an iron core and coils (windings) or permanent magnets wound around the iron core. The rotor rotates in a magnetic field, cutting magnetic field lines.
2、 The working principle of the power generator
Establish magnetic field:
In an AC generator, the rotor winding (excitation winding) is supplied with direct current to generate a rotating magnetic field.
In a DC generator, the magnetic field is generated by the excitation winding on the permanent magnet or stator, and the direction of the magnetic field is fixed.
Mechanical energy drives rotor rotation:
The prime mover (such as steam turbine, water turbine, wind turbine, diesel engine, etc.) provides mechanical energy to drive the rotor of the generator to rotate.
Cutting magnetic lines generates electromotive force:
When the rotor rotates in a magnetic field, the conductor (or magnetic field) on the rotor cuts the magnetic field lines in the stator winding.
According to the law of electromagnetic induction, an induced electromotive force is generated in the stator winding.
Output electrical energy:
The induced electromotive force drives the current to flow in the stator winding and outputs electrical energy through the terminal block.
In an AC generator, due to the constantly changing relative position between the rotor magnetic field and the stator winding, the output current is AC current.
In a DC generator, AC power is converted into DC power output through the action of a commutator (rectifier) and a brush.
The working principle of the power generator is based on the law of electromagnetic induction, which drives the rotor to rotate in a magnetic field through mechanical energy, cuts magnetic field lines to generate induced electromotive force, and converts mechanical energy into electrical energy. Different types of generators (such as AC generators, DC generators, synchronous generators, asynchronous generators, etc.) have different working principles, but the basic principles are the same.
