modelMotorEfficiencyMethods
Validation model for different motor efficiency options
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This is a simple validation model for
BuildingSystems.Fluid.Movers.BaseClasses.FlowMachineInterface
where its motor efficiency ηmot is specified with
different methods defined in
BuildingSystems.Fluid.Movers.BaseClasses.Types.MotorEfficiencyMethod.
The instance eff4 specifies ηmot as
a function of motor PLR by finding a generic curve with the maximum motor
efficiency and rated motor input power. The generic curve is generated by
BuildingSystems.Fluid.Movers.BaseClasses.Characteristics.motorEfficiencyCurve.
