Development of a Program that Visualizes the Magnetic Field in a Leneary Motor

Abstract

The Linear Single Induction Motor (LSIM) is obtained by cutting a rotary asynchronous motor along its longitudinal axis and developing it on a plane. The LSIM is one of the different conceivable structures that seems to be the most used. Its specific nature requires more powerful analysis methods to determine the distribution of the electromagnetic fields involved. The finite element method allows modeling in a very detailed way all the phenomena that occur within the linear induction motor. The finite element method, especially in two dimensions applied to the longitudinal section of a linear single induction motor, consists of describing the geometry of the section to be meshed in a plane, and then solving the general equations of electromagnetism. The purpose of our study is to implement the equation governing the operation of the LSIM and solve this equation using a numerical method that is of a nonlinear and non-stationary parabolic type due to the saturation of the medium.
