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

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.
