applications such as pumping and building ventilation. New technology now enables efficient VFD operation in medium voltage (2,300 – 6,900 V) fan applications. The primary benefit of a variable frequency drive is that it allows motors to operate at reduced speeds, and thus at a lower power, without a loss of torque. VFDs also allow for efficient
The obvious workaround is to place the VFD in a nonhazardous control room and run conduit and motor cable to the process in the hazardous area. But finding space to house VFDs, as well as the difficult and complicated installation involved, often proved too expensive and timeconsuming to .
Advancements made in the development of drive technologies means users have a myriad of options when selecting a drive system. Low voltage (LV) variable frequency drives (VFDs) have been applied to applications up to 2500 horsepower (HP). Medium voltage (MV) VFDs have been applied to applications as low as 150 HP.
Variable Frequency Drive (VFD) can be used in lots of fields. Variable frequency drives are widely used to control the speed of AC motors, like conveyor systems, blower speeds, pump speeds, machine tool speeds, other applications that require variable speed with variable torque.
Mine VFDs are used for pumping, for ventilation, for the actual mine process, and for transport. Especially in pumping and air handling applications, VFDs can be significant energy saving devices, allowing a mine operator to keep more of his hard earned profits.
