Polyphase inductance

Information

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.
