AC Motor efficiencies

Dear List

I am working on some software that estimates the energy requirement of a particular process (large scale reverse osmosis sea water desalination)
incorporating a state of the art energy recovery device called a work exchanger. When the user does not have information regarding the
efficiencies of the motors being used, I want to be able to estimate these efficiencies. I would like to base these estimates on real numbers. I have looked at a number of Ac Induction motor manufacturer's sites but have not found any efficiency numbers. I am interested in Ac induction motor efficiencies across a very broad spectrum of powers starting at 100KW right
up to 2MW. The larger motor would have to operate at 6.6KV.

Can anyone point me to a site that contains efficiency numbers for premium efficiency motors?


Thanks & Best Regards
