Asynchronous generator

Generator is a device for backup or main electrical generation. It will help out during emergencies and rolling blackouts, in the absence of access to a centralized power supply line, in field conditions (fishing, hunting, picnic). When choosing an autonomous station, you should pay attention to its characteristics. Including the type of alternator. It can be synchronous or asynchronous. An asynchronous generator is a budget option when current fluctuations do not matter.

How do asynchronous generators work and in what areas are they most effective?

Compared to a synchronous generator, an asynchronous generator has a simpler design due to the absence of carbon brushes and rotor windings. This device is also called brushless.

The magnetic field is transmitted without tight contact. The rotor rotates in the same magnetic field as the stator. In this case, the rotor rotates slightly faster.

The output produces current with fluctuations that reach up to 10%. Sudden fluctuations have a negative impact on equipment. Therefore, the brushless station is not suitable for sensitive equipment. However, not all devices are sensitive to current changes. An asynchronous power plant can be used in the following areas:

• construction;

• repair;

• road transport works.

The brushless device is immune to short circuits, therefore it is used to power high-power equipment. For example, for welding equipment.

An asynchronous generator cannot operate without an engine. You can start the engine manually without effort.

When choosing an autonomous power plant, power is taken into account. It should be enough to supply all consumers. In order not to make a mistake with your purchase, you need to know in advance the total power of all devices. The recommended surcharge is 25-30% in case of connecting new equipment.

What features and advantages of asynchronous generators should be taken into account when choosing?

Although an asynchronous generator cannot boast of the same performance as a brushed model, it has 6 undeniable advantages.

1. There is no need to change brushes. Synchronous devices require regular brush replacement. Brushless models do not have such a requirement, and accordingly, the cost of maintenance is reduced.

2. Protection from dust and moisture. The design of the brushless power plant provides increased protection from dirt and moisture. Models with a protective casing are impervious to precipitation and dust.

3. Less engine overheating. Due to the absence of direct contact between the rotor and stator, intensive cooling is not required, because the mechanism does not overheat, which has a positive effect on the service life of the unit. Air cooling is often used.

4. Lightweight and small in size. Thanks to its simplified design, the asynchronous generator weighs less. For example, a device with a fuel tank capacity of 15 liters weighs 43 kg. The model with wheels and handle is convenient for transportation.

5. Low noise level. The device makes a little noise when the motor is running. For example, a gasoline station with an open casing and a rated power of 3 kW has a noise level of 65 dB.

6. Price. Brushless units are more affordable than synchronous ones. The cost is determined by the simplicity of the design and the absence of expensive elements.

In the online store you can buy an asynchronous generator at a competitive price and with a quality guarantee from world-famous manufacturers. A wide range of single- and three-phase models are suitable for 220 or 380 V equipment. Price, small size and ease of maintenance make the brushless station an ideal choice for equipment that is not sensitive to voltage surges.

Asynchronous generators: technology and application in modern energy

For consumers who are undemanding to current drops, an asynchronous generator is suitable. It is also called brushless. In its design, unlike a synchronous (brush) power plant, there are no carbon brushes and windings. Due to this, the mechanism has a simplified design, overheats less and, accordingly, weighs less.

The asynchronous generator is used in modern energy. It is used to power heavy equipment with high energy consumption. At the same time, voltage drops are not important for consumers.

Most often, a brushless station is purchased to power welding equipment. Welding is not afraid of current surges and short circuits, so this electrical installation is the optimal solution. It ensures stable operation of the welding machine without interruptions due to short circuits.

Also, the asynchronous generator is suitable for servicing:

• a small hydroelectric power station and a wind power station;

• heating devices;

• large construction equipment.

The advantage of a brushless electric generator is the ability to work in rooms with heavily polluted air. This installation is protected from the penetration of small fractions into the mechanism, which allows it to be used on construction sites without fear.

Using Asynchronous Generators Efficiently: Tips for Maximizing Energy Efficiency

An asynchronous generator without a motor weighs little, and the total weight and dimensions of the unit together with the brushless motor are acceptable for frequent transportation. For example, the Mustang Star MSG 9800 model, with a fuel tank volume of 15 liters and a rated power of 2.8 kW, weighs 40 kg and has dimensions of 400x600x600 mm.

As for fuel, gasoline models are more common. This is due to the fact that the brushless motor itself weighs little due to the absence of windings and brushes. To further facilitate the mechanism, gasoline fuel is used for its operation. Gasoline units, compared to diesel ones, weigh less and are easier to transport. This is important in construction conditions, when the electrical installation needs to be moved from floor to floor.

To maximize energy efficiency, use an asynchronous generator within its capacity limits. Avoid working to the point of wear and tear. For example, if the maximum power of the installation is 4 kW, there is no need to connect devices that consume more energy to it. Do not bring the device to peak load. To prevent the system from overheating, try not to constantly consume maximum power. This way you will extend the life of the electrical unit.

Another tip for optimizing energy efficiency is to use high-quality gasoline. The surrogate negatively affects the operation of the mechanism. In addition, to generate 1 kW of energy, more surrogate will be required than high-quality fuel. The fuel consumption of a brushless installation (compared to a brushed one) is small. For example, the Kraft&Dele KD-146 model with a rated power of 1.3 kW and a fuel tank volume of 5 liters consumes 0.4 liters of gasoline per hour.

To buy an asynchronous generator and not be disappointed with the purchase, give preference to trusted manufacturers. These products are distinguished by high build quality.
