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.
