An interview with Southwire Company’s Steve Wetzel highlights how proper variable frequency drive (VFD) cable termination ...

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 ...

Many of us will have experimented with brushless motors, and some of us will have built our own controllers rather than using an off-the-shelf part. Doing so is a good way to understand their ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

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 speed control. Learn about SFPM calculations and how belt grit choices affect ...

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 ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

Motor control centers (MCCs) were first introduced in 1937 as a way to conserve wall and/or floor space in industrial facilities. Before 1960, wall-mounted motor starters were used even if only a few ...

ECM’s 5kW Unum Potentia controller powers ultra-efficient motor systems and greater optimization in a smaller package at a fraction of the cost. NEEDHAM, Mass.--(BUSINESS WIRE)--US Electric motor ...
