AC Variable Frequency Drives (VFD)

AC drives, also known as an AC variable frequency drive (VFD), adjustable frequency drive (AFD), variable voltage/ variable frequency (VVVF) drive, variable speed drive (VSD), AC drive, micro drive or inverter drive, provide adjustable motor speed and torque control through varying motor input frequency and voltage. Continual advancements in semiconductor switching devices and power electronics technology has reduced overall cost and size of the current VFD. Add improvements in drive topologies, simulation and control techniques, and overall software enhancements, these devices are key in any electro-mechanical control system providing cost savings in energy and improved machine efficiencies. There are several of these that you may come across, however the most common types are induction, synchronous, sensorless vector, and servo motors. From Simple pump and fan applications to general conveyor systems to high performance machine control, we have the right drive for your application.
