    OverviewSystem description and operationProgramming a VFDStarting and Software BehaviorBenefitsVFD types and ratingsApplication considerationsHistorical systems

    A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface. The AC electric motor used in a VFD system is usually a three-phase induction motor. Some types of single-phase motors or synchronous motorscan be advantageous in some situations, but generally three-phase induction motors are preferred as the most economical. Motors that are designed for fixed-spee
