Variable Frequency Drive (VFD)
What is Variable Frequency Drive (VFD)?
A Variable Frequency Drive (VFD) (also known as AC Drive, Inverter, Adjustable Frequency Drive, Adjustable Speed Drive, Variable Speed Drive Or Variable Frequency Variable Voltage Drive) is a type of equipment used in electro-mechanical drive systems to control & manage motor speed and torque by altering motor input voltage and frequency.

Frequently Asked Questions
A Variable Frequency Drive (VFD) is an electronic device used to control the speed and torque of an electric motor by adjusting the frequency and voltage supplied to the motor. It works by converting AC (alternating current) to DC (direct current) using a rectifier, then inverting it back to AC with a variable frequency, allowing precise motor control.
The choice between VFDs and VSDs depends on the specific requirements of your application. VFDs stand out in scenarios demanding high precision and energy efficiency, while VSDs are more suited for applications where simplicity and robustness are key. As an industrial engineer, weighing these advantages and limitations against the needs of your project will guide you to the most appropriate and efficient solution.
A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFDs vary the speed of an AC motor by varying the frequency to the motor. VSDs referring to DC motors vary the speed by varying the voltage to the motor, widely used in modern industries.
