Abstract: This paper describes a new method to identify the equivalent circuit parameters from finite element modelling and optimisation tool. The optimisation strategy is interesting one, because it allows to find a set of equivalent circuit parameters with only 4 known results instead of solving a polynomial of degree six (or more) and then looking for more known variable and results. The proposed method has three highlight points. The first point is that this new method will make it possible to split stator and rotor leakage inductances. The second one is that the equivalent circuit parameters are depending on working point saturation state. The last one is that the used quantities can be extracted either from modelling or from measurements.
