Variable Frequency Drive Information
If you have found Precision Electric on the web chances are you need a variable frequency drive replaced, serviced, or maybe you don’t even know what a variable frequency drive is.
Variable Frequency Drives are electronic devices used to control the speed of an Alternating Current Motor; typically these AC electric motors are used for industrial manufacturing. Variable Frequency Drives can also be known as inverters, electronic soft start devices, VFDs, adjustable speed drives and/or AC drives.
Variable Frequency Drives have a wide range of application use in several different industries. Here are a few of the more common applications and industries drives are used in:
- Food Processing/Packaging
- Wastewater Treatment
- Automotive Manufacturing
- Pharmaceutical Manufacturing
- Water Works Municipalities
- Steel Mill Industries
- Conveyors
- Chillers
- Cooling Towers
- Pumps for Hot Water Heating Systems
- Water Circulating Pumps
- Geothermal Heat Pump Systems
- Variable Air Volume Systems
- Injection-molding Equipment
- Air Compressors
Variable Frequency Drives operate as load controls within these applications that may accomplish up to 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 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 to become a cost efficient way to reduce energy costs and increase system efficiencies. Today manufacturing around the globe within a wide range of industries are finding more ways to apply Variable Frequency Drives to their manufacturing equipment.
