In this paper, a nonlinear magnetic equivalent circuit is presented as an
analytical solution method for modeling of a permanent magnet linear
synchronous motor (PMLSM). The accuracy of the proposed model is verified via
comparing its simulation results with those obtained by two other methods.
These two are the Maxwell?s Equations based analytical method and the
wellknown finite elements method (FEM). Saturation and any saliency e.g.
slotting effects can be considered properly by both nonlinear magnetic
equivalent circuit and FEM, where it cannot be taken into account easily by
the Maxwell?s Equations based analytical approach. Accordingly, as the
simulation results presented in this paper confirm, the proposed nonlinear
magnetic equivalent circuit is compatible with FEM regarding the accuracy
while it requires very shorter execution time. Therefore, the magnetic
equivalent circuit model of the present paper can be considered as a
preferable substitute for the time consuming FEM and approximated analytical
method built on Maxwell?s Equations in particular when required to be applied
for a design optimization problem.
