WHAT IS A VFD?
Variable frequency drives (VFDs); also known as variablespeed drive, AC drives, inverter drives, adjustable-frequency drives or microdrives control motor speed/torque by varying input frequency & voltage. Found in systems from small appliances such as ceiling fans to large industrial centrifugal systems VFD’s offer an energy efficient alternative to mechanical drives. Especially in industrial, agricultural & municipal applications.
VFD’s are not only long term solutions to system torque/speed control since the required maintenance of the drive is decreased (no belts to replace, lubricants to ads, gears to replace etc) they are often easy to
install to existing motor starters. An early issue surrounding the installation of VFDs was panel space, though as the technology has improved inverters are now able to be mounted separately on some models.
WHY SWITCH TO A VFD?
WHAT MAKES IT DIFFERENT
THINGS TO CONSIDER
While VFD’s are recommended in applicable systems that does not means issues are impossible. Possible issues include debris building up in heatsinks. As a result, the system can become overheated and damage components.
Extreme and/or drastic environmental temperature changes can also result in connections with in VFD to loosen. As well excessive vibration of a VFD can result in components being loosened or damaged. As mentioned earlier, these
common issues are linked to the environment the VFD is installed compared to wear and tear issues of the systems working as intended.
