What is VFDs?

A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. VFDs are commonly used to control the speed of AC motors, offering energy savings and improved process control in applications like pumps, fans, and compressors. They can also soft start motors to reduce mechanical stress.
