Comparison of equivalent circuits of eddy current loss models

Information

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.

Parameters

Modelica.Magnetic.FundamentalWave.Examples.Components.SinglePhaseInductance

Single-phase inductance

Information

This example compares an electric single-phase inductor with an equivalent fundamental wave reluctance circuit. The phase inductance L and the magnetic fundamental wave reluctance R_m are related by:

R_m = effectiveTurns^2 / L

The two currents

• resistor_e.i
• resistor_m.i

show the same waveforms and thus prove the equivalence of the two different modelling approaches.

Parameters

Modelica.Magnetic.FundamentalWave.Examples.Components.PolyphaseInductance

Polyphase inductance

Information

This example compares an electric polyphase inductor with equivalent fundamental wave reluctance circuits, one with reluctances individual for each phase (s) and the other with a common reluctance for all phases (m). The phase inductance L and the magnetic fundamental wave reluctance R_m for reluctances individual to the phases (s) and for a reluctance common to all phases (m) are related by:

R_ms = effectiveTurns^2 / L
R_mm = effectiveTurns^2 / L * m / 2

The currents

• resistor_e.i[1]
• resistor_s.i[1]
• resistor_m.i[1]

show the same waveforms and thus prove the equivalence of the different modelling approaches. Note that the number of initial equations (which depends on the number of phases m, too) depends on either individual or common implementation of the reluctance.
