Flux Linkage (Magnetostatic)
To compute the magnetic flux linkage, the magnetostatic field solver uses the following relationship:
where
defines the flux linkage due to self-inductance in a coil,
is the flux linkage due to mutual inductance between coils (i ≠ j), and
is the permanent magnetic flux linkage.
The energy method is used to calculate the inductance of a winding, which is then multiplied by the current flowing in the winding to get the flux linkage.
To obtain a correct flux vector, all current-carrying coils must be made part of the L-matrix computation. If you leave out L-entries that belong to current-carrying coils, the fluxes will be incorrect. (Refer to Inductance in Terms of Flux Linkage and Currents for additional information.)
