[bldg-sim] motor efficiency vs. VFD speed

Does anyone know of published research that relates motor efficiency to percent load as well as drive frequency?
We have motor curves for efficiency vs. percent load, but these curves all assume a nominal speed that is being maintained as load decreases. What happens to your motor efficiency when you are also changing the drive frequency?
Thanks for any leads.
