Motors
Motors are the most common source of power used by pumping systems. This technology is heavily regulated. Pumps by themselves are not variable speed, an option that many systems need to operate with peaks and ebbs during the run cycle, such as power generation. The addition of a variable frequency drive (VFD) gives it that capability.
Guidelines for reduced vibration and information on how a pump’s foundation and operating speed affect the vibration response
Ease of installation, improved algorithms, enhanced displays, onboard communication and other technology make VFDs an ideal and cost-effective solution.
The construction, seals and protective monitoring contribute to the motor’s ability to operate in and under water.
Use a mathematical model that estimates vibration at the top bearing of a motor used on a vertical, wet-pit, column type pump.
Advanced VFD technology delivers cost and space savings by providing protective features and minimal programming.
A dewatering facility brings a centrifuge up to speed slowly, meeting the long acceleration time requirement.
A VFD and a permanent magnet, direct-drive motor replace a gearbox, reduce maintenance costs and provide energy savings.
