Frequency Converters in Modern Process Automation
Frequency converters are important elements of advanced automation systems, thanks to their numerous advantages in improving the efficiency of electric motors.
Advantages of Frequency Converters
These devices provide a significant increase in the longevity of asynchronous motors, as they ensure a smooth start when used. Among the main advantages:
- Reduced power consumption by the electric motor;
- Decreased energy losses during startup;
- Energy savings of up to 75%.
The main areas of application for frequency converters include water supply, heating, ventilation, and air conditioning. The use of these devices helps to reduce the risk of accidents in pipelines and heating networks while simultaneously lowering electricity costs.
Thyristor Frequency Converters for DC Motors
Today, thyristor frequency converters are used for the stable operation of DC motors. They provide control over the rotational speed of the motor shaft, adapting it to changes in load. This reduces maintenance costs and increases the reliability of the system by optimizing the operation of elements such as bearings and fasteners.
Main Areas of Use for Frequency Converters
Frequency converters are applied in three main directions:
- Water Supply and Heating: Ensure the required pressure level in pipes, reduce carrier consumption, and minimize the risks of hydraulic shocks.
- Industry: Used for smooth starting of electric motors and speed regulation, which affects the quality of the produced products, particularly in the production of polymers, fiberglass, and paper products.
- Precise Positioning: Frequency converters with feedback can operate at zero speed with a high torque, which is especially important for precision mechanisms.
Thus, frequency converters contribute to increased energy efficiency and reliability of automation systems in various industries and infrastructure.
