Explanation: A VFD (Variable Frequency Drive) is used to control the speed, torque, and power consumption of AC motors. VFDs can be used to control the speed of pumps, fans, and conveyors, as well as to control the power consumption of motors. This allows for more efficient and precise control of industrial processes.
