More and more often, variable frequency drives (VFDs) are used for control of fans and compressors in HVACR systems. The benefits are well documented and industry acceptance is such that most electric ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

Watch a major upgrade: a motor swap on a big belt grinder to install a powerful 4.4kW (5.9hp) three-phase motor with VFD ...

It shows the vector motor control and one the of best sensorless vector control frequency inverters. Vector control is one of the most popular electrical motor control modes in electric industry that ...

Motor swap on my big belt grinder to install a 4.4Kw (5.9hp) three-phase motor controlled via VFD for speed controls. The dial indicates "surface feet per minutes" (SFPM), calculated from wheel ...

What does a simple cascaded conveyor system look like? How to integrate a conveyor system using only the digital capabilities of modern variable frequency drives (VFDs). Simplifying the automation ...

Learn what smart hydraulic power pack design looks like. Most hydraulic circuits are not a continuously operating system—the energy consumption during idle periods is substantial. The use of the VFDs ...
