A number of choices are available when connecting pumps, fans and other rotating equipment to an electric motor. There are numerous mechanical and fluid coupling designs and, in some cases, a belt drive option is available.
Last month, we ended with a discussion of the relationship between peak and RMS (or effective) voltage.
Following the development of variable frequency converter drives during the 1990s, totally enclosed fan-cooled (TEFC) AC induction motors became viable options for replacing DC motors in pumping applications.
With highly reliable electrical systems, protective relays may be called upon to operate very infrequently.
The industrial motor world has a new specification available for defining the requirements of general purpose, severe duty motors in the 250- to 3,000-hp range.
Advanced motor protective relays provide superior protection for motors and pumps. pump system optimization
A flexible coupling's primary functions are connecting two shafts, transmitting power from a driver shaft to a driven shaft and accommodating the misalignment between them.
Couplings are often forgotten until a project is nearing its end.
It has been said that Washington, D.C., is the home of the largest invertebrate population in the U.S.
Because operational costs ride on efficiency determinations, accurate measurements of losses occurring within the motor are paramount. The reliability of efficiency data is key to any energy-savings plan, and knowing the meaning behind the rating can make or break a smart purchasing decision.
Proper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability.
