With the advancement of technology and the growth of electronic industries, companies have been forced to use various electronic equipment that use industrial inverters or electric motor speed control drives for better exploitation of industrial automation lines. One of the most important parts in any industry that is related to electrical equipment are electric motors, which due to their high importance in monitoring and controlling equipment, in recent years, various types of them are available under the name of industrial inverters. Companies were placed.

inverter

VFD variable frequency drive or inverter literally means converter, in fact inverters can convert the frequency and voltage produced by existing amplifiers to the voltage required by the user, that is, for example, the existing AC power with the help of inverters to the level They deliver the customer’s wishes and control and start the three-phase AC motors. The presence of inverters in production and automation lines controls the speed of electric motors, and sometimes inverters are called speed control inverters.

Advantages of using an industrial inverter

This device is of interest to many industrial manufacturers due to its high and useful applications, but among its most important advantages, the following can be mentioned:

• Increase system efficiency and reduce energy consumption
• Ability to control the speed and speed of the electric motor
• Reduce device noise
• Torque control in the system
• Reduce the initial motor current
• Reducing producer costs and affordability
• Reduction of mechanical shocks
• The possibility of turning off the electric motor with a gentle slope

In addition to all the mentioned cases, in industrial inverters there is the possibility of networking and when working in the production line, they have the ability to detect ERRORs, which increases the efficiency of the system and better monitoring of the production line. In addition to all the mentioned points, energy saving, low initial current draw at the time of starting, as well as intelligent control facilities of electric motors can be considered as three important reasons for using industrial inverters.

Application of industrial inverters

Among the most important applications available for inverters, we can mention the control of the speed of fans and pumps, as well as the control of the torque of cranes and lifts, which are the most common uses of this part. But the main issue is the use of this tool in different industries according to the needs of that industry. Single-phase to three-phase or three-phase to three-phase inverters are among these that are used in industries such as industrial fans, pumps, booster pumps, elevators and compressors, printing and weaving machines, cranes. , lifts and plastic injection devices are used.

Difference between VFD, AC drive with inverter and drive

If you want to tell you the difference between these items in one sentence, we must say that they have no difference and the function of all of them is the same. In electronics, an inverter is a device that converts DC current into AC current. But due to the use of electronic modules for variable frequency control, these remote controller drivers are called inverters.

Industrial inverter structure

In general, two types of industrial and solar inverters are used by companies. The performance of industrial inverters is such that by converting the input current to DC and regenerating it, the input current is converted to AC power. To control the motor, this frequency can be easily controlled due to having a step waveform for the output current of the motor, which makes the inverter easy to control the device.

Types of industrial inverters

According to the needs of the collection, inverters with different control applications are available, the most famous of which are Siemens, Is, Schneider, Delta, Jafran, ABB, etc. brands. Various Asian and European brands are always interested in producing quality inverters in different models with various kilowatts based on the needs of their users.

The price of industrial inverters

The price of inverters is different based on the model, type and kilowatt of the device. Also, factors such as single-phase or three-phase and light or heavy use of the device determine their price. For example, the price of an inverter suitable for pumps or fans is much lower than an inverter used for lifts and cranes.

Important points when buying industrial inverters

At first, it is better to consider the type of use of the device and your needs, the power consumption of the device as well as the time it is used by you can be among the determining factors when you buy. It is better to avoid buying devices that are much more powerful than your consumption capacity, because not only will you not use all its control modes, but you will have to pay a lot of money. When buying industrial inverters, be sure to keep the following things in mind:

• Electric motor power
• Type of use of electric motor
• The length of time the device can be active
• Paying attention to the type of electricity input to the inverter (whether it is single phase or three phase)
• Considering the environment in which the device is placed
• Paying attention to the type of control mode of the device to control the engine speed

Considering the existence of different brands in the market and also the difference between models, it is better to get help from an expert in this field when buying inverters to buy the best option according to the type of need and use.
