Description

The eddy current loss model with respect to fundamental wave effects is designed in accordance to FluxTubes.Basic.EddyCurrent.

Fig. 1: equivalent models of eddy current losses

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 G_c , 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 v_k and i_k 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.
