FAQ :: VFDs | What Is A Variable Frequency Drive (VFD)?

/in /by
Variable Frequency Drives (VFDs) are electronic devices used to control the speed of an Alternating Current Motor (AC Motor). Variable Frequency Drives (VFDs) are also commonly known as adjustable frequency drives, adjustable speed drives, AC drives and inverters.
Variable Frequency Drives (VFDs) have a wide range of application use that include, but are not limited too:
Variable Air Volume Systems
Circulating Pumps for Hot Water Heating Systems
Chilled Water Circulating Pumps
Geothermal Heat Pump Systems
Injection-molding Equipment
Air Compressors
Conveyors
Chillers
Cooling Towers
Variable Frequency Drives (VFDs) operate as load controls within these applications that may accomplish up to a 50% reduction in energy costs. In general, an electric motor will turn at a rate proportional to the frequency of the alternating current (AC) applied to it. The majority of Variable Frequency Drives (VFDs) in the market today contain electronic circuitry that converts a 60Hz Line power into direct current. The VFD converts this line power into a pulsed output voltage that duplicates varying alternating current to a desired frequency.
Advances in technology over the past decade have allowed for Variable Frequency Drives (VFDs) to become a very cost efficient way to reduce energy costs and increase system efficiencies. More and more companies within a wide range of industries are finding more ways to apply Variable Frequency Drives (VFDs) to their applications.
