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. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.Frequency (or hertz) is directly related to the motorâs speed (RPMs). In other words, the faster the frequency, the faster the RPMs go.ll AC Variable Frequency Drives are designed to control 3-phase motors, but not all of them will accept single phase power input. The output of the drive is not exactly a true 3-phase AC power, it is a DC generated square-wave, simulated 3-phase power.
