A variable frequency drive is used for adjusting a flow or pressure to the actual demand. It controls the frequency of the electrical power supplied to a pump or a fan. Significant power savings can be achieved when using a VFD.
A variable-frequency drive is a system for controlling the rotational speed of an alternating current electric motor. It controls the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, or inverter drives.
Automatic frequency control consist of an primary electrical circuit converting the alternating current into a direct current, then converting it back into an alternating current with the required frequency. Internal energy loss in the automatic frequency control is rated ~3.5%
Variable-frequency drives are widely used on pumps and machine tool drives, compressors and in ventilations systems for large buildings.
