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
About 25% of the world''s electrical energy is consumed by electric motors in industrial applications, which can be more efficient when using VFDs in centrifugal load [clarification needed] service; however, the global market penetration for all applications of VFDs is relatively small.
application and use In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil. Because VFDs improved process performance and reduced maintenance costs, they replaced motor generator sets and DC drives.
Is your mining application earth leakage relay VFD suitable? May 18th, 2016 Filed under Safety and Protection Relays. The mining industry is experiencing a growing number of applications of Variable Frequency Drives (VFD) to soft start and control motors driving shovels, draglines, hoists, conveyors, longwalls, mills, fans and pumps.
This webinar reveals how variable frequency drives (VFDs) can improve efficiency and process control in underground mining applications. It reviews motor and variable speed drive technology, and explores optimizing electrical system efficiency of mining applications, including fans, mobile mining equipment, and 1000 Volt Power Systems.
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 .
