A VFD (Variable Frequency Drive) is a device that can control the speed of an AC motor by varying the frequency and voltage of the power supply. VFDs have many industrial applications, such as in air handlers, pumps, chillers, tower fans, conveyors, tool changers, transfer lines, etc.123
Some benefits of using VFDs are:
They can save energy and reduce operating costs by adjusting the motor speed to match the load requirements.
They can improve the performance and efficiency of the motor and extend its lifespan by reducing mechanical stress and wear.
