The magnetizing field of a linear generator used to obtain electrical energy from waves energy

Abstract

The paper studies the magnetizing magnetic field, the radial and axial forces of a linear electric generator used to convert the marine wave’s energy. The study takes into account different sizes for the permanent magnets and the relative position of the moving armature over the stator and shows when the magnetizing flux is maxim. For different positions of the moving armature the radial and axial forces are computed. The magnetic field and the forces are computed on finite element method basis using FEMM
