Performances of buried permanent magnet synchronous generator with flux concentration for the wind system

Abstract

This article proposes a different way of studying the performances of the structure of permanent magnet synchronous generator for small wind turbine. Thus, we make the two-dimensional study of the synchronous buried permanent magnet generator with flux concentration. It will be a question of studying the influence of the geometrical parameters of this generator on its performances: Effective no load flux, the phase resistance and cyclic inductance. We are interested in the parameters which appeared to us most relevant: dimensions of the permanent magnets, geometrical parameters principal expressing the obstruction of the machine and dimensions of the stator's teeth. Results of simulations obtained in the Matlab environment starting from the analytical model, we could identify the parameters which influence the performance of the generator positively and which could be used as variables of optimization.
