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 ...

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 ...

MEAN WELL's compact, fanless variable frequency drives (VFDs) are engineered for use with energy-efficient three-phase motors and designed to help industrial customers improve energy efficiency, ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

Deciding where to put your drives requires more than just casual consideration. If your VFDs are failing prematurely, it may be because they're located in your motor control centers (MCCs). MCCs ...

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 ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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 ...

Five Large AWG Symmetrical Variable Frequency Drive (VFD) cables and five Signal Brake Pair VFD cables have been added to the vendor’s line of flexible VFD cables for industrial AC motor drive ...
