functionmotorEfficiencyCurve
This function generates the generic curve for motor efficiency based on rated motor power
Extends from Modelica.Icons.Function (Icon for functions).
Information
This function generates a generic motor efficiency curve based on the rated motor power input and maximum motor efficiency according to U.S. DOE (2014) (shown below). It returns a constant array if the rated power is unavailable.
