A basic electrical safety rule is that water and electricity do not mix.
In 2011, I wrote a five-part series on alternating current (AC) motors and motor efficiency. This column will go into more detail about the impact of efficiency.
Today’s industrial marketplace uses many different machines—such as pumps, fans, compressors and conveyors. One machine that is often overlooked is the centrifuge.
More than ever, commercial building owners and industrial process users need to reduce their maintenance costs and achieve energy savings.
You have probably noticed that three-phase motors can have a varying number of leads exiting the junction box. The most common numbers are three, six, nine or twelve.
According to the Department of Energy, motor-driven equipment—such as pumps, fans and compressors—consume about 16 percent of the energy used in U.S.
