This paper details a study performed by the Irrigation Training and Research Center to determine motor performances under varying speeds [induced by a variable frequency drives (VFD) controller] and loads. A further goal of the study was to provide sufficient information to designers so that they could estimate total pumping plant power usage with a VFD-controlled installation. Motors were tested with a VFD as well as across-the-line. On average, the relative efficiency of the electrical system… Expand

A novel method to determine the motor efficiency under variable speed operations and partial load conditions
TLDR
A new and original concept of “load ratio” is brought forward to describe the motor performances and a simple method is proposed to estimate the motor efficiency under variable speeds operations and partial load conditions using load ratio, speed ratio, rated motor power and rated motor efficiency.

TLDR
It was determined that the present IEC standard is not reliable, and does not offer the possibility to the consumers to make an instructed choice, because the additional load losses are not properly taken into account. Expand
