Variable Frequency Drives, or VFDs, are electronic devices used to control the speed and torque of electric motors by varying the motor input frequency and voltage. Commonly used in industrial and commercial applications, VFDs enhance energy efficiency, reduce mechanical stress, and allow precise control over motor-driven systems like conveyors, pumps, and fans. By adjusting motor speed to match operational needs, VFDs help reduce energy consumption, optimize performance, and extend equipment life.
