VFD Cables

filter_list

VFD cables are a type of specialized electrical cable designed for use with Variable Frequency Drives (VFDs) or Adjustable Speed Drives. These drives are used to control the speed and torque of AC motors in a variety of industrial motion control applications.

VFD cables are designed to handle the harsh electrical environment that can be associated with these drives, which can produce high voltage spikes and generate a significant amount of electrical noise. This environment can cause cable failure and even equipment failure if not properly managed.

The key component of VFD cables that helps them manage this environment is their construction. They often feature a tinned copper conductor, which provides excellent electrical conductivity, and a ground conductor that provides a ground path to help manage electrical noise. Some cables may also feature a copper tape shield to further reduce noise.

More Information about VFD Cables

One important concern with VFDs and their cables is the issue of high voltage spikes. These can be caused by the rapid switching frequencies of the VFD and can result in the phenomenon known as corona discharge, which can damage the cable and other equipment. A high-quality VFD cable is designed to withstand these spikes, making it a proven solution for protecting your equipment.

Another key feature of VFD cables is their ability to handle the common mode noise generated by VFDs. This noise can cause problems with other equipment in the vicinity of the VFD, so the right VFD cable can play a vital role in preventing this issue.

In addition, VFD cables are designed to handle higher voltages that are often associated with VFD applications. This makes them suitable for use in a broad range of industrial settings.

FAQs

Is a variable speed drive the same as an adjustable speed drive?

Yes, the terms "variable speed drive" (VSD) and "adjustable speed drive" (ASD) are often used interchangeably in the context of motor control. Both refer to a type of drive that can vary or adjust the speed of an electric motor.

 

Motor Starters, Soft Starters and VFDs

Motor Starters

Motor starters safely start and stop a motor in industrial applications. They are designed with a contactor, overload and circuit protection. They are used when basic motor control is required, where torque on the motor is not a concern and speed control is not needed. The advantages of motor starters include: lower cost, allows for remote operation, allows for monitoring of motor state (with the use of auxiliary contacts) and they are safe and efficient. The disadvantages include: high inrush current that can cause fuses to blow and breakers to trip if the inrush is too high, and the starter will allow a full torque to start the motor which can cause the motor to ramp up to full speed very quickly potentially causing the motor to wear and degrade prematurely.

Soft Starters

Soft starters protect motors from inrush current by gently ramping up the motor to full speed. They provide all of the same functions as a traditional motor starter. The advantages of soft starters include: they are less expensive than a VFD when only startup control is needed, they are a smaller system than a VFD where space is a concern and they prevent unwanted torque upon startup, prolonging the life of the motor. The disadvantages include: they are more expensive than a traditional motor starter and they do not allow for full speed control. 

VFDs

A Variable Frequency Drive (VFD) allows for the slow ramp up of a motor during startup and the slowing down of the motor during shutdown. It also allows for full speed control during the entire run cycle of the motor. VFDs provide the same functions as both the traditional motor starters and soft starters. The advantages of VFDs include: full speed control (start, stop and in-between), more custom control and monitoring, energy savings due to efficient motor usage and less wear and tear on the motors. The disadvantages include: they are more expensive and larger than other motor control options and they generate heat that may require fans or AC units.
