In the modern market there are several typeselectric generators: synchronous, asynchronous, inverter. Despite one purpose, they have significant differences, which directly affects the production of energy. Let's get to the specifics of each type of generator.
The synchronous type generatora unit operating in the power generation mode. Its feature is the equal frequency of rotation of the magnetic field of the starter in relation to the rotor speed. Magnetic poles together with the rotor generate a rotating magnetic field, which after the transition through the winding of the starter forms an electromotive force in it. In a generator of this type, the rotor is an electromagnet or a permanent magnet.
Such a constructive feature gives the synchronous generator such advantages as:
The main disadvantage of synchronous generators is their susceptibility to moisture and dust.
Synchronous type generators are recommendeduse if it is necessary to supply devices having a high starting current, for example, pumps, circular saws. Power plants of this class are also desirable to use for connecting household appliances.
Mobile power plant of asynchronous typeis the engine that uses the braking mode for operation. This means that the rotor and the magnetic field of the starter rotate in one direction, but with a certain amount of advance. The rotating magnetic field can not be reconfigured, so that the output frequency and voltage always depend on the rotor speed.
The advantages of generators of an asynchronous class are:
The main negative nuance of asynchronous power plants is that they do not tolerate starting currents.
asynchronous type is recommended for connectionelectric welding, as this ensures a more even seam. They are resistant to moisture and dust and therefore can work smoothly at various enterprises, construction sites, streets. Asynchronous power plants should be connected devices for which the voltage and frequency of the current does not play an important role.
An inverter-type generator is a mechanism in whichwhich is generated by the internal combustion engine, and then it is sent to the power electronics, where it is transformed into a permanent one and charges the built-in battery. After this, the DC current must be transformed again into an alternating current. To do this, in the chain after the battery there is an inverter, which generates at the output 220 V at a frequency of 50 Hz.
The advantages of this design aremore economical fuel consumption, because the generator may not support the same speed of rotation of the shaft. In addition, the speed of rotation may be low, but this will be enough to fully charge the battery. And the lower the speed of rotation, the less the generator consumes fuel. The inverter system allows you to get a stable level of electricity, and therefore additional measures to protect the equipment will not be needed.
Inverter generators are considered to be the most economical, since they are able to adapt to the actual load. If it is small, then the generator automatically switches to the economical operation of the engine.
Among the disadvantages of an inverter generator isnote battery. If it breaks, the generator will not be repaired, and you will have to replace it with a new one. Also worth noting is the high cost of an inverter-type generator. For it you will have to pay twice as much as for a synchronous or asynchronous type.
It is necessary to connect highly sensitive equipment: computers, microwave ovens, boiler equipment, modern audio and video equipment.
As a result, it turns out that to connect morepart of household appliances it is worthwhile to use synchronous generators, it is recommended to buy asynchronous models to connect equipment, and for inductive devices it is necessary to buy inverter power plant.
