How Much Do You Know about Frequency Converter?

Difference between frequency converters and variable frequency drives

Frequency converter: it comes to mean the existence of a frequency conversion equipment whose purpose is to adapt a power source.
Variable frequency drive: Refers to devices used as variable frequency generators.

Whether we use one term or use the other, they are both correct concepts to refer to the same function . The most widespread and used, however, is the frequency variator.

Uses of the frequency converters in the Industry

The uses of frequency converters are quite wide within the industrial sector. They cover not only different types of uses within the company, but also various industrial sectors .

Frequency converters used for various machinery:

  •  Compressors
  •  Cranes
  •  Lifts and hoists
  • Winches
  •  Pumping water
  • Solar pumps
  •  Cooling tower

The use of frequency converters in any of these machines always has the same function: to control their rotational speed, specifically that of the motors. This function can be performed by a single device, or a group of devices, be they mechanical, hydraulic, electrical or also electronic.

Frequency converters for different industrial sectors:

Within the different sectors of the industry, frequency converters are essential. In order to make companies profitable, it is necessary to use motors at variable speeds, without affecting their efficiency . As a result, the motors connected to these devices can be used in all kinds of applications.

  •  Cement Industry
  •  The Chemical industry
  •  Navy sector
  •  Metallurgy
  • Mining sector
  • Oil and Gas Industries
  • Plastics and Rubber
  • Power generation sector
  •  Water treatment
  • Pulp and paper processing

 

In summary, all the frequency converters, what they do is: they supply variable voltage and frequency according to the needs of the motor . To do this, they connect to the electrical network, which has a fixed voltage and frequency, and transform electricity to a continuous voltage. Once this is done, they create a three-phase alternating voltage with variable magnitude and frequency.
