Abstract


The Linear Induction Motors (LIM) belong to the Group of electric machines that convert electrical energy directly into mechanical energy in the form of translational motion. Thus, unlike the rotary machines, linear motors are capable of producing linear motion, without the need for mechanical couplings as belts or gear sets, resulting in greater precision and acceleration in the positioning of the moving piece. This work presents a study of the behavior of the magnetic field and their amplitude along the stator and the rotor of a LIM. Computational analysis of magnetic flux is made using a free computer program (FEMM-Finite Elements Methods on Magnetics), based on theory of "finite elements". Through this analysis it is possible to develop prototypes of LIMs with maximum efficiency, relating to mechanical power delivered to the load.
