This paper presents the modelling, simulation and comparative study between switched reluctance generator 8x6 and switched reluctance generator 12x8. During work, the structural properties of the rotor and stator laminates of these machines are exposed. This information was used to perform mathematical modelling for both topologies. Based on this modelling, a computer simulation model was developed in the Simulink/Matlab® environment where several tests were carried out. To ensure comparability between machines, the output power in both topologies was set to 735,5 VA. After analyzing the results obtained during the simulations, it was found that the topology of the switched reluctance generator 8x6 is more efficient than 12x8
