Abstract

 The paper presents the assessment of the mechanical torque of a two-dimensional magnetic gearbox used in energy harvesting applications by increasing the low mechanical power speed of wind turbines. The simplified device doesn’t consider the rotational speed transmission from the inner magnetic rotor to the outer magnetic rotor; in this case, the outer magnetic rotor behaves as a stator, alongside the ferromagnetic pole pieces. The numerical simulation analysis considers a parametric study to address the influence of the dimensions of the outer magnets on mechanical torque. The results are obtained using the finite element method (FEM).
