Excerpt from article:

"Those who are trying to more accurately size motors to the specific needs of an application say they’ve changed their practices because of better understanding of motor/system requirements (19.6 percent) or improved system designs that are more flexible (13.8 percent). Others point to stricter design requirements (2.9 percent) or tighter cost controls (9.4 percent)."
