  • VFD - Variable Frequency Drives

    Variable Frequency Drives A Variable Frequency Drive is a motor control device that protects and controls the speed of AC induction motors. From the VFD basics theory, we know a VFD can control the speed of the motor during the start and stop cycle, as well as throughout the running cycle by outputting adjustable frequency.It also refers to as Variable Speed Drives (VSD), …

    1:40. If we multiply this ratio by maximum frequency we can determine the minimum speed which the VFD can run and still maintain control of the motor. For example, with a 60 Hz maximum frequency and 1:40 control range, a drive using the V/f control method can control a motor all the way down to 1.5 Hz.
