variable frequency drive

A Variable Frequency Drive (VFD) controls the speed of an AC electric motor by varying the frequency and voltage supplied to it. This allows for precise speed control to match the demands of the application, improving efficiency and reducing energy consumption. VFDs often include features for motor protection, such as overload and overcurrent protection. They are widely used in industrial applications for controlling pumps, fans, conveyors, and other motor-driven equipment. By optimizing motor speed, VFDs contribute to significant energy savings and process control.
