Generators Are A Very Important Function

The role of generators is to convert other forms of energy into electricity. The most common is the conversion of mechanical energy into electricity, as far as the mechanical energy, can be the combustion of coal released from the boiling water generated steam to promote the rotation of the turbine produced. It can also be caused by wind blowing of wind turbines; common photovoltaic power generation is the conversion of light energy into electricity.

The generator is a very important role in automobile parts, Generators once the generator has no electricity output, the car will not start, this is the owner worried about the situation. But the principle of the generator presumably everyone is unfamiliar, the following to learn about it.

Generators are usually composed of stator, rotor, end cover, Generators base and bearing and other components.

The stator is composed of a stator core, a coil winding, and other structural parts fixing these parts.

The rotor is made of a rotor iron core (magnetic choke.) Slip ring, (also known as copper ring).

The stator and the rotor connection of the generator are assembled by the bearing and the end cover, Generators so that the rotor can rotate in the stator, do the movement of the cutting magnetic field, thus generate the inductive potential, lead through the terminal terminals, and then generate the current in the loop.


The generator, which is equipped with a turbine, is called a generator. In order to achieve high efficiency, the steam turbine is generally made at a high speed, usually 3000 rpm (frequency 50 khz) or 3600 RPM (frequency 60 khz). In the nuclear power plant, the turbine speed is lower, but also at 1500 rpm/min. Generators In order to reduce the mechanical stress caused by centrifugal force and reduce the wind and friction, the rotor diameter is generally smaller and the length is larger, which is the use of slender rotors. Especially in 3000 rpm/min High speed units, Generators due to the relationship between the strength of the material, the rotor diameter is strictly limited, generally not more than 1.2 meters. The length of the rotor body is limited by the critical speed. When the length of the body reaches 6 times times the diameter, the second critical speed of the rotor will be close to the speed of the motor, and there may be a larger vibration in the driving, so the contour of the generator is limited. About 100,000-kilowatt of the air-cooled motor rotor size has reached the above limit size, to increase the capacity of the motor, Generators only by increasing the electromagnetic load to achieve. The cooling of the motor must be strengthened. Therefore, more than $number million kilowatts of generators with a good cooling effect of hydrogen cooling or water-cooled technology. Since the 70, the maximum capacity of generators has reached $number million kilowatts.

The components in the generator are also quite large, and each component is connected to each other in order to output power through the generator and the vehicle will be activated.
