What is a variable frequency drive?

A Variable Frequency Drive (VFD) is an electronic device used to control the speed and torque of electric motors by varying the frequency and voltage supplied to the motor. VFDs are commonly used in industrial and commercial applications to improve energy efficiency, process control, and reduce mechanical stress on equipment. By adjusting motor speed to match the application's needs, VFDs help save energy and prolong the lifespan of machinery. They are especially beneficial in systems like HVAC, pumps, and conveyors where variable speed is required.
