Inductance calculations

Once all winding calculations n for a specific machine are available, the various inductances can be computed according to the following formula:

where k₀ and k₂ are geometrical coefficients obtained from electrical parameters and intermediary inductance calculations; x in brackets is the expected value of X, p the number of pole pairs, and theta the rotor electrical angle.

The inductances can be expressed in a more convenient form:

L_yx0, Ly_x1, and L_yx2 are computed before the simulation. This expression could be further reduced to a single trigonometric function with a phase term but its computational  cost in quite high for faulty machines with numerous parallel windings.
