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 topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
As the march continues to make motor efficiency nearly 99%, the way motors are used and applied can make a big difference in the overall sustainability picture of any plant.
In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
