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 ...

In this episode, we connect with Steve Wetzel, a member of IEEE and principal applications engineer with Southwire Company, one of North America's largest wire and cable manufacturers and the sponsor ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

Targeting ac-motor-drive applications, the symmetrical VFD (varying-frequency-drive) cables carry power from industrial ac-drive systems to ac motors. A dual-copper-tape shielding provides a ...

Designed for use on larger, more-powerful ac motor drives, five VFD cables extend the product range from Size 1 to 4/0 awg. The cables feature three stranded XLPE TC circuit conductors and two ...

Experts examine the procedure of commissioning, running it up and checking it out, medium-voltage VFDs rated 250 hp (186.4 kW) and larger at a minimum 2.3 kV voltage level. Equipment commissioning is ...
