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.
