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.
