Summary
The primary research objective of this study was to determine motor efficiencies under varying speeds (induced by a VFD controller) and loads. A broader objective was to provide sufficient information to designers and economists so that they could estimate total pumping plant power usage with a VFD-controlled installation. Motors were tested with VFDs as well as across-the-line.
