What are frequency inverters and how do they work?

Frequency inverters, also known as inverters, are electronic devices used to control the speed of electric motors by adjusting the supply frequency and voltage. Their basic function is to adapt the motor speed to the actual requirements of the system.
Conventional electric motors without regulation operate at a constant speed, which often leads to unnecessary energy consumption and higher mechanical loads. With frequency inverters, the motor operating speed can be adjusted in real time, providing much more efficient control of the entire drive system.
This type of regulation provides:

• reduced electrical energy consumption,
• softer electric motor starts,
• lower mechanical loads,
• reduced component wear,
• more stable system operation,
• more precise production process control,
• longer service life of motors and drive elements.

A correctly selected frequency inverter can significantly improve the efficiency and reliability of an industrial process.

Benefits of using frequency inverters in industry

The use of frequency inverters in industrial systems brings numerous benefits that have a major impact on operating costs and production stability.
One of the main benefits is certainly energy efficiency. In applications such as fans, pumps or conveyor systems, motors often do not need to run at maximum speed. By regulating speed, the system can operate according to the current demand, which noticeably reduces electrical energy consumption.
In addition to lower energy consumption, frequency inverters also provide:

• reduced starting currents,
• less vibration,
• less wear on bearings and mechanical components,
• better motor protection,
• fewer production stoppages,
• quieter system operation,
• better process automation.

In many industrial sectors, they are now an important element in optimizing production and reducing maintenance costs.

Single-phase frequency inverters for smaller systems

Single-phase frequency inverters are primarily used in lower-power applications and with smaller electric motors. They are often used in:

• smaller conveyor systems,
• ventilation systems,
• smaller machines,
• workshop equipment,
• simple automation systems.

Their main advantages are simple integration, compact design and efficient speed control at lower loads.
Our range includes different models of single-phase frequency inverters from 0.18 kW upward, providing stable operation and reliable electric motor control.

Three-phase frequency inverters for demanding industrial applications

Three-phase frequency inverters are used for higher loads and more demanding industrial systems, where higher power ratings and more advanced functions are required.
Such inverters are used for:

• production lines,
• CNC machines,
• industrial pumps,
• large fans,
• mixers,
• lifts,
• automated conveyor systems.

Three-phase frequency inverters provide stable speed control even at higher loads and give better control over system operation. Thanks to advanced functions, they can also be integrated into modern automated processes and industrial control systems.

The importance of choosing the right frequency inverter

Choosing the right frequency inverter is crucial for reliable system operation. When selecting one, the following must be considered:

• electric motor power,
• type of application,

Ten frequently asked questions:

1. What are frequency inverters and how do they work?
Frequency inverters, also known as inverters, are electronic devices that control the speed of electric motors by changing the supply frequency and voltage. Their basic function is to adapt the motor speed to the actual requirements of the system.
Conventional electric motors without regulation operate at a constant speed, which often results in higher energy consumption and additional mechanical loads. With frequency inverters, the rotational speed can be adjusted in real time, resulting in more efficient and stable system operation.
This type of solution provides:

• lower electrical energy consumption,
• softer motor starts,
• reduced component wear,
• better process control,
• longer service life of electric motors.

2. Why use frequency inverters in industry?
The use of frequency inverters brings many benefits for industrial systems and production processes. One of the main benefits is optimization of energy consumption, as motors operate only with the power and speed required.
In addition to energy efficiency, they also provide:

• reduced starting currents,
• lower mechanical loads,
• less vibration,
• more stable system operation,
• more precise process control,
• lower maintenance costs.

In modern industry, frequency inverters are an important part of automation and production optimization.

3. What is the difference between a single-phase and a three-phase frequency inverter?
Single-phase frequency inverters are primarily intended for smaller electric motors and less demanding applications. They are often used with smaller fans, pumps, workshop machines and basic automation.
Three-phase frequency inverters are intended for larger industrial systems and more powerful electric motors. They are used in production lines, CNC machines, larger conveyor systems and more demanding drives.
The choice mainly depends on:

• electric motor power,
• supply voltage,
• type of application,
• speed control requirements.

4. How do frequency inverters reduce energy consumption?
In many industrial applications, electric motors do not need to operate continuously at maximum speed. Without regulation, the motor operates with the same power all the time, causing unnecessary electrical energy consumption.
Frequency inverters adjust the operating speed to the actual requirements of the system. In fans, pumps and conveyor systems, even a small speed reduction can noticeably reduce energy consumption.
This type of optimization often brings:

• lower operating costs,
• less system heating,
• more efficient operation,
• faster return on investment.

5. Where are frequency inverters most commonly used?
Frequency inverters are used in many industrial sectors and applications:

• conveyor systems,

• lifts,
• ventilation systems,
• compressors.

Their main role is to provide optimized electric motor speed control and stable system operation.

6. How to choose the right frequency inverter?
The selection of the right frequency inverter depends on several factors:

• electric motor power,
• load type,
• input voltage,
• working environment,
• control requirements,
• mounting method,
• communication with automation systems.

Correct sizing of the inverter according to starting loads and operating conditions is also important. An incorrect selection can cause overheating, unstable operation or a shorter system service life.

7. Do frequency inverters extend the service life of electric motors?
Yes, correctly used frequency inverters significantly reduce mechanical and electrical loads on electric motors.
Soft starts and gradual stopping reduce:

• impact loads,

This means fewer faults, less maintenance and a longer service life for motors and other drive components.

8. What do the designations IP20, EMC filter and PNP mean for frequency inverters?
When choosing frequency inverters, various technical designations are often encountered.
IP20 indicates the degree of enclosure protection against touch and ingress of foreign objects.
An EMC filter reduces electromagnetic interference and improves the stability of the electrical system.
PNP and NPN designations refer to the type of input/output signals used for connection to automation and control systems.
Understanding these designations is important for correct integration of the inverter into an industrial system.

9. Can frequency inverters be connected to automation systems?
Modern frequency inverters can be connected to various automation and industrial control systems.
