How does the frequency inverter have a positive effect on the field of modern industrial automation

HOW DOES THE FREQUENCY INVERTER HAVE A POSITIVE EFFECT ON THE FIELD OF MODERN INDUSTRIAL AUTOMATION

Ιt is a fact that in modern times, in which technology dominates, it is always necessary to control every machine and equipment. From small-scale functions that we encounter in our daily lives, such as electronic devices and in every production process, to processes that extend to long lengths and widths, eg in maritime applications, airports, even in heavy industry and cargo lifting. Especially for the industrial automated processes related to the production part that it is necessary for a smooth and trouble-free operation, there should be a monitoring system, which will control the output. This is achieved with the frequency inverter.

WHAT IS THE FREQUENCY INVERTER?

The frequency inverter is a device widely used in industrial automation to convert the AC frequency of the electricity that supplies the equipment. Based on a conversion circuit from external sensors and detectors, it can detect and determine the voltage it receives. It then automatically generates an output signal, which is proportional to the frequency, thus maintaining stability in the operation of each device applied.

It is estimated that in industrial applications electric motors and transmission systems consume too much electricity. However, when frequency inverters are integrated in these motors, their efficiency increases, their operation is normalized and their consumption is stabilized.

Especially in recent years, when the use of high-efficiency and low-consumption electric motors is now mandatory in most developed countries, several industries have been led to adopt and implement frequency inverters.

Therefore, several processes can reap many benefits, such as high accuracy in handling dynamic applications and optimized use of time, cost and resources in automation.

WHAT ARE THE ADVANTAGES OF USING A FREQUENCY INVERTER?

The use of special frequency inverters in applications that need industrial automation is accompanied by several advantages for their operation and performance. Specifically:

  1. They keep the starting current under control and help manage the operating speed

When an AC motor is started, it needs to consume up to twice the rated current and torque up to 200% of their rated power for a few seconds to achieve the rated speed from the standstill. Since it can exceed the required limit, the electric charge produces heat, which, over time, bends the windings of the electric motor, significantly affecting its service life.

On the contrary, with the use of a frequency inverter, the motor of each machine starts smoothly keeping the V/f ratio constant, while at the same time the condition of the motor is checked. As a result, its lifespan is extended. In addition, the application of a frequency inverter offers the possibility of increasing the speed range of each machine, as well as flexibility of use by its operator.

  1. Reduce power line problems and disruptions

Any possible voltage drop that may occur in the power cord may adversely affect equipment connected to the same distribution system. It usually includes components and devices such as sensors, switches and computers. The application of a SEW - EURODRIVE frequency inverter protects the electric motor to some extent from voltage fluctuations, even in case of overload.

For example, in the automotive manufacturing industry, the smooth running of construction processes is essential. Every minute of downtime can cost manufacturers who want efficient and flexible driving solutions and smart automation plans. Frequency inverters can be customized to meet the needs of any automated production activity and reduce the occurrence of problems with the uninterruptible power supply (UPS) dual conversion system.

The same applies in the food and beverage industry, where supply systems have to move large quantities of goods every day in order to be available and sufficient. Automatic control and fine torques ensure accurate placement and smooth handling of transported materials and this is achieved with frequency inverters.

  1. Save energy and costs

A frequency inverter enables us to fluctuate our output or line speed so that we can achieve higher efficiencies and automated processes without wasting energy. In addition, it eliminates the need for mechanical motion support components, making a significant contribution to reducing overall operating costs.
