How generators work, how generators work

Generators usually consist of stator, rotor, and end caps. Brushes. It is composed of components such as machine base and bearing.

The stator consists of a frame. The stator core, the wire-wrapped winding, and other structural parts that hold these parts in place.

The rotor consists of a rotor core, a rotor pole (with a magnetic choke. magnetic pole winding), slip rings, (also known as copper rings. collector ring), fan and shaft and other components.

The stator and rotor of the generator are connected and assembled through the bearing, the base and the end cover, so that the rotor can rotate in the stator, and a certain excitation current is introduced through the slip ring, so that the rotor becomes a rotating magnetic field, and the stator coil does the movement of cutting magnetic field lines, so as to generate an induced electric potential, which is drawn out through the terminal and connected to the circuit, and the current is generated.

From the perspective of physical structure, the stator and rotor of the generator are two parts that are completely independent and do not interfere with each other, in addition to the drag of a prime mover.

The stator of the generator is the active source, which generates induced electromotive force and current, and under the drag of the prime mover, the active power of the alternating current is output outward, and the amount of active power is determined by the motive force (oil volume, gas volume, air volume, water volume, etc.).

The rotor of the generator is a reactive power source, and the winding introduces direct current from the outside to establish a magnetic field, and under the drag of the prime mover, the reactive power of the alternating current is transmitted to the outside, and the reactive power is determined by the direct current of the external input (most of which are obtained by the spontaneous alternating current rectification of the generator).

From the electromagnetic principle, the rotor and the stator are precisely linked, the active and reactive power of the generator are output by the stator, the torque of the rotor determines the size of the active power, and the DC current of the rotor coil determines the size of the reactive power.

Electromagnetic Induction Phenomena Oersted experiments show that magnetic fields exist around energized wires as well as around permanent magnets. The Oersted experiment revealed a very important essence - there is a magnetic field around the current, and the current is generated by the directional motion of the charge, so the magnetic field around the energized wire is essentially generated by the moving charge.

Please refer to the principle of the generator.

Generators use the principle of electromagnetic induction, and the generation of electricity is the manifestation of electromagnetic induction.

The principle of operation of generators is the law of electromagnetic induction.

A generator is a mechanical device used to convert the mechanical energy of an object into electrical energy, and when a part of the conductor of a closed circuit is cut in the magnetic field, the inductance line is transported and defeated, and the conductor will induce a current. The generator uses electromagnetic induction to transform the work. It works by converting other forms of energy into mechanical energy through a power mechanical drive, which is then converted into electrical energy by a generator.

However, the working principle of different types of generators will be slightly different, for example, diesel generators are driven by diesel fuel, and then the energy of diesel is converted into electricity; The gasoline generator is driven by gasoline to drive the motor, and then converts the energy of gasoline into electrical energy; Finally, the alternator produces electrical energy by generating alternating current through electromagnetic induction.

Classification of generators:

1. DC generator.

The DC generator is a generator that converts mechanical energy into DC electrical energy. Generally, there are four types: permanent magnet, separate excitation, parallel excitation and compound excitation. It is mainly used as a DC motor for DC motors, electrolysis, electroplating, electrometallurgy, charging and excitation of alternators.

2. Alternator.

The alternator alternates the direction of the current emitted, and the speed of the change, that is, the frequency changes, with the change of the speed of the generator. Usually 50Hz is used with 60Hz in foreign countries. Compared with the DC generator, the direction of the current is constant, so there are positive and negative poles.

3. Solar generator.

Solar generators are a kind of power generation imitation method that uses sunlight shining on semiconductors such as silicon and photons to directly convert light energy into electrical energy to generate the photoelectric effect generated when photons hit atoms.

Generator refers to the mechanical equipment that converts other forms of energy into electrical energy, which is driven by water turbines, steam turbines, diesel engines or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it 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 all based on the laws of electromagnetic induction and electromagnetic forces. Therefore, the general principles of its construction are:

Magnetic circuits and circuits that use appropriate magnetic and conductive materials to generate electromagnetic power and achieve the purpose of energy conversion.

Generators work by converting the energy of diesel into electricity.

In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector, and under the extrusion of the piston upward, the volume is reduced, and the temperature rises rapidly to reach the ignition point of the diesel. The diesel fuel is ignited, the gas mixture burns violently, and the volume expands rapidly, pushing the piston downward, which is called work.

Key features:

1. Working characteristics: The main characteristics that characterize the performance of synchronous generators are no-load characteristics and load operation characteristics. These characteristics are an important basis for users to choose generators.

2. No-load characteristics: when the generator is not loaded, the armature current is zero, which is called no-load operation. At this time, the three-phase winding of the motor stator only has the no-load electromotive force E0 (three symmetrical) generated by the excitation current if induced, and its magnitude increases with the increase of if.

However, due to the saturation of the core of the motor magnetic circuit, the two are not proportional. The curve that reflects the relationship between the no-load electromotive force e0 and the excitation current if is called the no-load characteristic of the synchronous generator.

Pro, the generator is a device that converts mechanical energy into electrical energy, and its working principle can be briefly described as follows: the generator is mainly composed of two parts: a stator and a rotor. Among them, the stator is a stationary electromagnet that encloses a number of coils; The rotor is a rotating electromagnet driven by mechanical energy, and several coils are also enclosed.

When the mechanical energy drives the rotor to rotate, the coil in the rotor will move next to the coil of the stator, at this time, due to the principle of electromagnetic induction, an electromagnetic induction electric potential will be generated in the coil of the stator, so as to generate voltage at both ends of the stator, that is, electric energy. The magnitude of this voltage is related to the rotation speed of the rotor, the number of turns of the coil row, the magnetic flux, and other factors. The generator converts from mechanical energy to electrical energy by rotating the coils of the rotor and stator, and when the input of mechanical energy increases, the output of the power produced by the generator will also increase.

As a result, generators have important applications in the production, transmission, and storage of electrical energy.

Hello dear, the working principle of generators is to convert mechanical energy into electrical energy. When the rotor of the generator rotates, the magnetic field lines pass through the coils in the generator, inducing an electromotive force. The magnitude of the electromotive force depends on the strength of the magnetic field, the number of turns of the coil, and the speed at which the coil rotates in the magnetic field.

In this case, due to the voltage difference between the two ends of the coil, electrons flow through the circuit, forming an electric current. In this way, the conversion process of mechanical energy to electrical energy is completed. The core parts of the generator are the stator and rotor.

The stator is immobile and is generally fixed to the core by several coils. The rotor, on the other hand, rotates and consists of several permanent magnets or electromagnets. When the generator is working, the motor drives the rotor to rotate, so that a rotating magnetic hall field is formed around the coil in the stator, which induces an electromotive force.

The working principle of the generator is described by mathematical formulas, and its principle is very complex and requires the help of knowledge in the field of electromagnetism. In simple terms, generators require energy input, which is converted into electricity through the interaction of the rotor and stator.

Hello dear<> the working principle of the generator is based on the principle of electromagnetic induction. The generator converts mechanical energy into electrical energy, and it is composed of two main parts: the rotor and the stator. The rotor is a magnetic pole that rotates in a magnetic field, and it is driven by many strong currents, which generate magnetic flux when it rotates.

The stator is placed around the rotor and wound into a number of coils, in which the current is usually supplied by an external power source or other electric motor. When the rotor rotates, the magnetic field of the rotor passes through the coils of the stator and changes, which will result in the generation of an electromotive force on the stator. The electromotive force causes some electric currents in the stator circuit, and these nonsense currents can be alternating current or direct current, depending on the type of generator.

The periodic change of current creates an electromotive force between the stator's coil and the internal load, and an electric current in the external load, which is converted into electrical energy. The output power of a motor is usually expressed in watts or kilowatts and depends on the mechanical power of the driving rotor, i.e. the speed and torque values. In short, the working principle of the generator is to convert mechanical energy into electrical energy output by using the electromagnetic sensing principle between the rotor and stator, and can generate alternating current or direct current as needed.

It is one of the important energy conversion equipment for modern industrial and domestic life.

Hello, a generator is a device that converts mechanical energy into electrical energy. Its basic principle is to use the principle of action of the magnetic field to output electrical energy through the wire by the electromotive force generated by rotation. Specifically, the working principle of a generator can be broken down into three steps:

1.The rotor creates an electromotive force: inside the generator there is a rotating rotor in which brushes and electric coils are housed.

When the rotor rotates, the brushes come into contact with the electrical coil, forming a loop. According to Faraday's law of electromagnetic induction, an electromotive force is generated in this loop and an electric current is generated within the electrical coil. 2.

Electrical energy output: The current generated by the rotor is output to the outside through the wire and becomes the form of electrical energy. In this process, the voltage and current will also vary depending on the circuit load.

3.Magnetic field action: There is also a stationary stator inside the generator, in which there are also electric coils.

When the rotor rotates, an electromotive force is generated by the electric coil in the stator through a magnetic field. In this way, the entire generator forms a closed circuit, and through the interaction between the rotating rotor and the fixed stator, the mechanical energy of the machine is converted into electrical energy. Through these three steps, the generator is able to convert the mechanical energy generated by the rotation into electrical energy output.

This is also how most of the electrical equipment we use in our daily lives works. Hopefully mine will give you a better understanding of how generators work! (＾u＾)ノ
