Polyphase inductance
This example compares a quasi static electric polyphase inductor with an equivalent quasi static fundamental wave reluctance circuit.
The phase inductance L
and the magnetic fundamental wave reluctance R_m
are related by:
R_m = m * effectiveTurns^2 / 2 / L
The real parts
resistor_e.i[1].re
resistor_m.i[1].re
and the imaginary parts
resistor_e.i[1].im
resistor_m.i[1].im
of the two currents show the same result and thus prove the equivalence of the two different modelling approaches.

Comparison of equivalent circuits of eddy current loss models
In this example the eddy current losses are implemented in two different ways. Compare the loss dissipation powerb_e.power
and powerb_m.power
of the two models indicated by power meters.
