The U.S. Department of Energy (DOE) is empowered by congress to review efficiency regulations for covered products every five years.

Electric motor systems with variable frequency drives (VFDs) are becoming more common in large industrial systems because VFDs provide higher system efficiency, greater operational flexibility, im

When thinking of a food manufacturing facility, many people may envision a lockdown area in which all personnel must wear full-body decontamination suits and where every internal surface of the fa

Because of advanced control capability and potential energy savings, the use of adjustable frequency drives (AFDs) for motor control is expanding rapidly throughout many industries and environment

In the industrial sector, cost is often the driving force when evaluating capital projects.

Intelligent motor control centers (MCCs) provide the data to support safe, reliable and more efficient operations, making information available for process monitoring, advanced diagnostics and pre

I hope that my last column (Pumps & Systems, September 2014) provided a clea

Many industries use variable frequency drives (VFDs) with induction motors. Introduced in the 1960s, VFD technology has advanced considerably during the past 50 years.

Q. Are the pump motors special for VFD operation or can any motor be used with a VFD?

Located in one of the fastest growing regions in the U.S., the Benton/Washington Regional Public Water Authority (BWRPWA) broke ground in 1996 for a water treatment facility serving northwest Arka

Inexperienced vibration analysts encounter a common problem: They are often expected to learn too much, too fast.

Power factor (PF) is an important component of an alternating current (AC) circuit, but understanding its actual effect can be difficult. Why is PF mysterious to many of us?

In my July 2014 column, I demonstrated that three-phase voltage variation can significantly affect several alternating curre

Motor manufacturers routinely answer questions about the differences between submersible and immersible motors and the applications best served by each design.

Paper production requires large amounts of power. The Smurfit Kappa plant in Piteå, Sweden, uses its own biomass boilers to meet part of its energy needs.

In my June column on pump and motor testing, I said that three-phase voltage variation and unbalance can have a significant effect on motor insulation life.

The term “testing” covers a range of processes. Parts supplied for motor manufacturing are tested as they are manufactured and when they arrive at the plant.

Bearing currents occur in specific motor and drive installations and can lead to motor fatigue and failure.
