Abstract

The paper presents the use of the finite element (FE) method for determining the parameters of a two-axis model of a three-phase linear induction motor. The model parameters are obtained from the FE field solutions. The saturation of the motor is taken into account in calculation of the flux distribution by using a static nonlinear vector potential solution. The linear time harmonic vector potential field solution is used for the determination of inductances. All inductances are determined at the nominal value of the magnetizing current. The parameters of the model obtained by the described identification procedure are compared with the parameters calculated in the conventional way and the agreement of results is quite good.
