Variable Frequency Drive (VFD) This device uses power electronics to vary the frequency of input power the motor, thereby controlling motor speed. User Manual Variable Frequency Drive 0. The Variable Frequency Drive Evaluation Protocol presented here addresses evaluation issues for variable-frequency drives (VFDs) installed on commercial and industrial motor-driven centrifugal fans and pumps for which torque varies with speed.
