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 ...

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 ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed elevating the frequency of power pulses/sec fed to motors for faster Increasingly common, variable frequency ...

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 ...

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 ...

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 ...

Jim Alt explains Nord Gear's new IE5 motor and variable frequency drive. These IE5 motors operate at high efficiency even at reduced speeds and with reduced loads. In this video, Alt explains the ...

Discover why impulse voltage insulation class (IVIC) is critical when selecting IEC motors for converter duty.

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 ...
