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.
