Theoretical analysis of the reversed claw poles alternator performances

The goal of this article is to present the reversed claw poles generator (RCPG)´s performances (magnetic flux, flux density and stator induced electromotive force) achieved by modifying the machine´s geometric topology. The magnetic flux density distribution is computed via two methods: magnetic equivalent circuit and finite element analysis. From the finite element analysis, the shapes of the induced electromotive force are also fetched. In order to perform the Fourier analysis of these wave forms, the FFT technique from Matlab SIMULINK is employed. The paper presents in detail the machine´s operational and external characteristics.
