Model Modelica.Magnetic.FundamentalWave.Components.EddyCurrent
The eddy current loss model with respect to fundamental wave effects is designed in accordance to FluxTubes.Basic.EddyCurrent.
|
Due to the nature of eddy current losses, which can be represented by symmetric
conductors in an equivalent electric circuit (Fig. 1), the respective
number of phases 
has to be taken into account.
Assume that the conductances
of the equivalent circuit are 
,
the conductance for the eddy current loss model is determined by
where 
is the number of turns of the symmetric electro magnetic coupling.
For such an phase system
the relationship between the voltage and current space phasors
and the magnetic flux and magnetic potential difference phasor is
,
,
where 
and 
are the phase voltages and currents, respectively.
The dissipated loss power
can be determined for the space phasor relationship of the voltage and current space phasor.
