Characteristics of EMC and VFD

EMC (Electromagnetic Compatibility) aims to ensure that electronic systems operate smoothly in electromagnetic environments and the cables, which has EMC protection, has special designs and test methods.

Due to electromagnetic interference can cause electronic systems to malfunction or fail, EMC protections increase the reliability and availability of system.

Cables can cause the transmission and propagation of electromagnetic interference while used for transmission of data and power in electronic systems. However, if cable’s design has well shielding, will provide resistance and durability against electromagnetic interference.

Many countries have established EMC requirements by laws and regulations. Therefore, compliance of products with EMC standards has become a necessity for sales and distribution in these countries.

In special applications and devices that require EMC compatibility, cables with EMC protection should be chosen.

VFD (Variable Frequency Drive) is an electronic device used to change the motor speed.

Especially used to control the speed of motors that used in industrial applications, by changing the supply frequency. Equipment can be controlled more precisely by using VFD, while energy efficiency is achieved.  VFDs also prevent the system from drawing high current, preventing excessive current overload on motor and electronic installations. When working with VFD system, it is necessary to use VFD cable that can withstand high voltage fluctuations. Using non-VFD cables may cause insulation deterioration and cable failure.

To summarize, EMC is about controlling electromagnetic radiation and ensuring electromagnetic compatibility, while VFD is a device used to control the speed of electric motors. They are frequently use together in industrial and electronic systems although they have different purposes.

Compliance with EMC requirements is important to ensure the electromagnetic compatibility of VFD and other electrical devices. Although the cabling of devices with these features is similar, operating voltages, number of cores and twisting patterns vary depending on their usage areas.

When choosing cables for your applications, you can prefer cables according to EMC needs or using for VFD motors.
