In most U.S. states, running a 100-horsepower pump motor continuously for a year can rack up more than $40,000 in energy expenses.
A new line of explosion-proof, inverter-duty motors provides a solution to the problem of electrical bearing damage caused by energy-saving inverters (also known as variable frequency drives) in p
Pumping systems account for a significant portion of a facility's energy use in many industries.
As the world's largest energy consumer, China is projected to consume two times more energy than the U.S. by 2040.
