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 ...

Variable-frequency drives (vfd’s) go by a number of different names, such as variable-speed drives, adjustable-speed drives, and adjustable-frequency controllers. It doesn’t really matter what you ...

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 ...

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 ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

For retrofits Electro Static Technology’s AEGIS® Shaft Voltage Test Kit makes it easier than ever to measure and document damaging VFD-induced voltages while there is still time to head off bearing ...
