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.
