DOE rules since 1992 have impacted the U.S. motor market.
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.
End users must consider many variables to choose the better solution.
This method of achieving variable speed pumping promotes energy efficiency and can pay for itself over a long period of service.
When following the new DOE guidelines, don’t forget these considerations.
Evaluating system requirements and all available options can improve reliability, efficiency and cost.
Achieving unity power factor through the use of synchronous condensers can be a win-win situation for power utilities and consumers.
The study will give industry stakeholders a better understanding of the marketplace and help them become more globally competitive.
This alternative technology is ideal for petrochemical applications.
Drives with active energy control can save energy and extend motor life for pumping and HVAC loads.
Today’s innovations in drive technology and design offer powerful benefits even beyond energy savings.
Corrections can be a sustainable, cost-saving measure and should be considered by companies with a large installation of these types of motors.
A Mississippi River levee, an Indiana water plant and an Ohio municipality take advantage of ease of installation and significant energy savings—as much as $2 million up front.
Achieve pump and motor longevity by providing proper storage, avoiding pre-service damage, and conducting sound handling and maintenance procedures.
Users should consider system changes to comply with the new EISA standard.
To ensure the best system setup, end users must first consider operating conditions, then conduct thorough cost-benefit calculations.
In plants that process combustible materials, these motors avoid electrical damage often caused by energy-saving inverters.
Process control software reduces costs while increasing process accuracy and protection.
The Chinese government is promoting greater automation and optimization of processes to improve the energy utilization rate.
