Abstract
This paper presents research results regarding the realization as unit block of the system made from a single-phase permanent magnet synchronous generator and a single-phase transformer. The proposed synchronous generator has double-gap, with high moment of inertia and axial magnetic field distribution. Built-in electrical transformer has toroidal core (effectively, the empty cylinder is made of electrical steel sheets) where are placed concentrated windings. The structure chosen for low power synchronous generator - with multiple air-gaps, axial magnetic field distribution and high moment of inertia - is particularly useful in conversion systems of wind energy in electricity because it allows the removal of mechanical gearbox for adjustment of aerogenerator output parameters at the input parameters of the electric generator (mechanical gateway). To envision some of the functional particularities, generated by constructive features of such an integrated system, in this paper was accomplished with PDE-ase software, an analysis of magnetic field distribution within the structure. In order to allow an overview regarding forces distribution in this integrated system, the maximum specific energies, existing in the structure were also determined, which along with Lagrangian formalism, were measured developed specific forces. In conclusion, the realization of such an integrated system is possible and recommended for remote sites where electricity is to be maintained parameters - obtained from wind energy - a certain level, without the intervention of power electronics.
