Electric motors are used pervasively in industry for industrial pumps, electric fans, compressed air systems, conveyors, material handling and more. Most of these motors run at full speed or they’re off. There is no middle-ground, because their speed can’t be altered on their own. As a result, they consume more electricity than required to do the job. Variable frequency drives (VFDs) can mitigate unnecessary power consumption in many industrial and commercial
applications by varying the speed (or frequency) of motors.
