Additional equipment and built-in technology move these drives into new applications.
Baldor Electric Company hosted its Fundamentals of Motors class, Dec. 1-3, to educate industry veterans and novices alike on everything motor-related, from basic parts and components to calculating...
Reduced downtime is an added benefit of sustainable procedures.
Enhanced diagnostics provide critical data for reliable, efficient operations.
I hope that my last column (Pumps & Systems, September 2014) provided a clearer definition of power factor and how it can be calculated. Power factor can also be explained using a vector triangle, but...
Discharges flowing through the bearings put motors at risk.
Q. Are the pump motors special for VFD operation or can any motor be used with a VFD? A. Yes. Today there are special motors that are rated to be used with a VFD. They are commonly called...
The Benton/Washington Regional Public Water Authority saved on energy costs and gave dependable service to its customers after replacement.
Revisiting the fundamentals of data examination, time and resolution can solve equipment issues before they happen.
Power factor (PF) is an important component of an alternating current (AC) circuit, but understanding its actual effect can be difficult. Why is PF mysterious to many of us? It has to do with the way...
In my July 2014 column, I demonstrated that three-phase voltage variation can significantly affect several alternating current (AC) motor characteristics. If that variation is large, it can also...
How do end users choose, and what are each type’s ideal applications?
Trusted gateway connections allow for system growth, efficiency and consistent maintenance at Swedish paper mill.
In my June column on pump and motor testing, I said that three-phase voltage variation and unbalance can have a significant effect on motor insulation life. Voltage variation is defined as the...
Manufacturers and operators produce, purchase and use better motors with regulated testing.
Price, operating costs and reliability are key factors in any TCO calculation.
The best option for preventing bearing currents depends on the source of the problem.
The updated regulations may require machine redesign and premium efficiency motors and components.
These are the details of the snowmaking machines used during the Winter Olympics in Sochi, Russia.
Price, operating costs and reliability are key factors in any TCO calculation.
Previous articles in this series explained how oversized piping systems can have higher operating and maintenance costs. Higher maintenance costs can adversely affect the reliability and uptime of...
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.
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. Efficiency defines how well a motor...
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.
