.Buildings.Fluid.Movers.BaseClasses.Characteristics.motorEfficiencyCurve

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.
