Nonlinear model based on inductance for switched reluctance linear motor

In this paper we present the nonlinear modeling of a linear switched reluctance motor. This modeling is based on the Fourier series decomposition of expression of the inductance, this model deals an overview of modeling to characterize the nonlinear behavior of the studied motor during its operation in saturation mode. The static characteristics of inductance obtained by a magneto-static finite elements model built for the studied is used to determine the coefficient of the Fourier series of the model. Then the obtained results by analytical model are compared with finite elements method obtained ones.
