Variable Frequency Drives (VFD)

What is a variable frequency drive?

A common component of motor control, a variable frequency drive is used to control the speed, torque, horsepower and direction of an AC motor. Known as VFD’s for short, variable frequency drives are used in fans, pumps, conveyors, processing machinery and more. VFD’s are solid state devices with no moving parts, making maintenance and installation a breeze. However, VFD’s are known to generate heavy harmonics and quite a bit of heat, but their benefits far outweigh these, as long as they are dealt with properly. The energy-saving, speed controlling characteristics are not only desirable but essential in AC motor applications.

The various types of variable frequency drives.

VFD’s are used anywhere motor control is required and have advantageous qualities that soft starters do not. They have a high power factor and by controlling the speed and torque of a motor, they save on energy while extending the lifespan of your motor. By managing the magnetic field of the motor and the speed and current during start up, they ultimately reduce the stress and wear placed on it. VFD’s are popular devices and are used throughout low and medium voltage applications. So whether you need a pump VFD, an AC drive, an HVAC VFD or a general purpose VFD, there’s a variable frequency drive perfect for your specific job.
