<DIV><FONT face=Arial size=2>Hello again</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I found the article that Fred Porter recommended at
ASHRAE's bookstore, in the Transactions section.</FONT></DIV>
<DIV><FONT face=Arial size=2>The article is titled <FONT face=Arial size=6><FONT
size=2><STRONG>Efficiencies of an 11.2 kW </STRONG></FONT><FONT
size=2><STRONG>Variable Speed Motor and Drive </STRONG>and has metered data of
both motor and drive efficiency at different loads and speeds. Not sure
how well this applies to larger motors, but it so happens that the motors I am
looking at right now are in this size range, so this does the
trick.</FONT></FONT></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks to others who pointed out the timely article
in this month's Engineered Systems, as well as a previous article in ASHRAE
Journal from 1999. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks again to all.</FONT></DIV>
