linearTemperatureDependencyConverts a value (e.g. resistance) from reference temperature to an actual temperature |
SystemModel["Modelica.Electrical.Machines.Thermal.linearTemperatureDependency"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This is the same function as Modelica.Electrical.Machines.Thermal.convertResistance but without physical units for input RRef and result R. This avoids problems if the function is used to calculate linear temperature dependency for other values than resistances.
From the temperature coefficient alpha20
at 20 degC (equals to 293.15 K) the parameter alphaRef
at TRef
alpha20 alphaRef = ------------------------------- 1 + alpha20 * (TRef - 293.15)
is determined; using this value, actual value (e.g. resistance R
) with respect to the actual temperature T
is calculated by
R ------ = 1 + alphaRef * (T - TRef) RRef
where RRef
is the value (e.g. resistance) at the reference temperature TRef
.
